How we can recycle more buildings

How we can recycle more buildings


The insatiable demand of the global building boom has unleashed an illegal market in sand. Gangs are now stealing pristine beaches to order and paradise islands are being dredged and sold to the construction industry was the introduction to an article of The Guardian. A less partial response to that would definitely that of Seyed Ghaffar, Brunel University London proposes here below to how we can recycle more buildings.


More than 35 billion tonnes of non-metallic minerals are extracted from the Earth every year. These materials mainly end up being used to build homes, schools, offices and hospitals. It’s a staggering amount of resources, and it’s only too likely to increase in the coming years as the global population continues to grow.

Thankfully, the challenges of sustainable construction, industrial growth and the importance of resource efficiency are now clearly recognised by governments around the world and are now at the forefront of strategy and policy.

A critical component of the UK government’s sustainability strategy concerns the way in which construction and demolition waste – CDW, as we call it in the trade – is managed. CDW comes from the construction of buildings, civil infrastructure and their demolition and is one of the heaviest waste streams generated in the world – 35% of the world’s landfill is made up of CDW.

The EU’s Waste Framework Directive, which aims to recycle 70% of non-hazardous CDW by 2020, has encouraged the construction industry to process and reuse materials more sustainably. This directive, which favours preventive measures – for example, reducing their use in the first place – as the best approach to tackling waste, has been implemented in the UK since 2011. More specific to the construction industry, the Sustainable Construction Strategy also sets overall targets for diverting CDW from landfill.

Policies worldwide recognise that the construction sector needs to take immediate action to reduce greenhouse gas (GHG) emissions, tackle the climate crisis and limit resource depletion, with a focus on adopting a circular economy approach in construction to ensure the sustainable use of construction materials.

Instead of simply knocking buildings down and sending the CDW to landfill, circular construction would turn building components that are at the end of their service life into resources for others, minimising waste.

It would change economic logic because it replaces production with sufficiency: reuse what you can, recycle what cannot be reused, repair what is broken, and re-manufacture what cannot be repaired. It will also help protect businesses against a shortage of resources and unstable prices, creating innovative business opportunities and efficient methods of producing and consuming.

Changing the mind-set

The mind-set of the industry needs to change towards the cleaner production of raw materials and better circular construction models. Technical issues – such as price, legal barriers and regulations – that stand in the way of the solutions being rolled out more widely must also be overcome through innovation.

Materials scientists, for example, are currently investigating and developing products that use processed CDW for manufacturing building components – for example, by crushing up CDW and using it to make new building materials.

Technical problems around the reuse of recycled materials should be solved through clever material formulations and detailed property investigations. For instance, the high water absorption rate in recycled aggregates causes durability problems in wall components. This is something that research must address.

Robots and AI should play a key role in future circular construction. Shutterstock

Moreover, it is illegal in the EU to use products that haven’t been certified for construction. This is one of the main obstacles standing in the way of the more widespread reuse of materials, particularly in a structural capacity. Testing the performance of materials for certification can be expensive, which adds to the cost of the material and may cancel out any savings made from reusing them.

For the construction, demolition and waste management industries to remain competitive in a global marketplace, they must continue to develop and implement supply chain innovations that improve efficiency and reduce energy, waste and resource use. To achieve this, substantial research into smart, mobile and integrated systems is necessary.

Radically advanced robotic artificial intelligence (AI) systems for sorting and processing CDW must also be developed. Many industries are facing an uncertain future and today’s technological limitations cannot be assumed to apply. The construction industry is likely to be significantly affected by the potential of transformative technologies such as AI, 3D printing, virtual/augmented reality and robotics. The application of such technologies presents both significant opportunities and challenges.

A model for the future

As the image below shows, we have developed a concept for an integrated, eco-friendly circular construction solution.

Advanced sensors and AI that can detect quickly and determine accurately what can be used among CDW and efficient robotic sorting could aid circular construction by vastly improving the recycling of a wide range of materials. The focus should be on the smart dismantling of buildings and ways of optimising cost-effective processes.

The industry must also be inspired to highlight and prove the extraordinary potential of this new construction economy. We can drive this through a combination of creative design, focused academic research and applied technology, external industry engagement and flexible, responsive regulation.

Only through a combination of efforts can we start to recycle more buildings, but I’m confident that with the right will – and the right investment – we can start to massively reduce the amount of materials we pull from the ground each year and move towards a truly sustainable future.

Adaptation to Climate Change in the MENA Region

Adaptation to Climate Change in the MENA Region


The World Bank in its “Adaptation to Climate Change in the MENA Region” predicted that this region being particularly vulnerable to climate change, it should do more to adapt to water scarcity and heat and adjust all institutional mechanisms to deal with these environmental constraints. Environmental awareness in the Arab world posted on The Arab Weekly of 17 Novembre 2019 is a good illustration of this latest trend.


Lebanon was the country with the strongest concerns about climate change in general, followed by Tunisia and Egypt.

Climate change is a global emergency that respects no borders but results from a recent survey revealed that, when it comes to convincing MENA populations to come to grips with the crisis, substantial barriers remain.

Recent data gathered by Arab Barometer, a nonpartisan research network that has conducted opinion surveys across the region since 2006, indicated that a strong majority of respondents said they were “very concerned” about water and trash pollution (70% and 66%, respectively). Both issues are immediate problems that MENA residents must often deal with directly and can see with their own eyes daily.

However, when it came to more abstract or long-term environmental issues, such as climate change and air quality, fewer survey respondents said they were very worried (35% and 44%, respectively).

Opinions showed no significant variations across age and gender groups. However, more educated and affluent respondents expressed slightly stronger concerns about climate change in general.

The survey uncovered dividing lines geographically: Residents in rural areas were more likely to view climate change as a “very serious” problem than those living in urban environments.

Lebanon was the country with the strongest concerns about climate change in general, followed by Tunisia and Egypt, but national differences on specific issues were the starkest. Air quality was considered a “very serious” problem for 57% of respondents in Libya but only for 25% of those surveyed in Kuwait.

The survey adds credence to the argument that a region-wide effort must be made to build awareness about climate change.

Algeria: distinguishing economic time from political time

Algeria: distinguishing economic time from political time

The new Law of Hydrocarbons in Algeria: distinguishing economic time from political time was enacted despite concurrent street demonstrations against it. It was debated at length by Professor Abderrahmane MEBTOUL, International Expert, in interviews to Radio Algeria International – Paris France on 04/11/2019, to Algerian Radio Channel-3 and to Radio France International on 05/11/2019. Here are some excerpts of each.

Algeria: distinguishing economic time from political time

Question – 1. Will Algeria with high domestic consumption be able to meet its international commitments?

Indeed, if we take natural gas, domestic consumption is likely to exceed 60 billion cubic meters of gas by 2030 and 100 billion cubic meters of gas between 2035/2040, the Ministry of Energy has announced the depletion of reserves would be at about 60%. An urgent need to review the current energy policy and move towards a clean energy transition policy that revolves around four axes, to meet its international commitments.

-First: an energy efficiency policy (energy sobriety) that affects all sectors and households by reviewing construction methods, cars/trucks fleet consumption, energy-intensive industrial units; the simple referring to a policy of targeted subsidies, but which do not penalize the disadvantaged, existing new technologies that save about 30% of energy consumption.

-Secondly: the development of renewable energies whose cost has fallen by more than 50% for both thermal and photovoltaics, where Algeria has significant potential.

-Thirdly: to continue to invest in upstream, which can make discoveries as part of a win-win partnership, SONATRACH with lower prices and physical production, which has dropped significantly since 2008, technological or financial capabilities, but no longer have to be deluded by large deposits like Hassi-Messaoud or Hassi-Ramel.

-Fourthly: avoid precipitation whilst developing SHALE oil and gas, Algeria having the third world reservoir, only by 2025, as I recommended to the authorities of the country, through this study with experts pending new technologies that replace hydraulic fracturing, saving freshwater and injecting more than 90% of the chemicals into wells, thus protecting the environment, but requiring in-depth social dialogue.

To answer your question directly, I highlighted the points at the 5 + 5 Meeting of Algeria, Morocco, Tunisia, Mauritania, Libya with France, Italy, Spain, Portugal, Malta in Marseille in June 2019. I had the honour of chairing the Energy Transition’s workshop in which the subject of a clean energy transition policy, and the modification by Algeria, a major energy player in the Mediterranean basin, as it has always done, to meet its international commitments by 2030.

Question – 2. Will the amendment of this law attract foreign investors?

Depending on several factors, such as:

-First: the revision of this law as I have pointed out since its enactment at the beginning of 2013 is unsuited to the current situation, in particular the tax component and the nature of the contracts in which Sonatrach supports the majority of the financing, the world having evolved from where the importance of its revision to take account of new global energy changes.

-Secondly: however, a law is only a legal instrument, being a necessary but sufficient condition of the attractiveness of foreign investment, where any company attracted by direct profit rate, and also as long as the level of foreign exchange reserves is high. Depending on the business environment where Algeria was in the latest report of the World Bank of 2019 was very poorly classified because of its paralyzing bureaucracy, corruption, financial and unsuitable socio-educational systems.

-Thirdly: the political climate is decisive, and according to international observers no serious investor would engage in Algeria without the resolution of the political crisis, political stability especially in a country like Algeria, where politics and economics are intertwined, being a determining factor in the attractiveness of a foreign investment.

-Fourthly: as I have just pointed out recently, to your colleagues on France 24 television, and several Algerian websites and daily newspapers, it would be desirable to postpone the adoption of this law after the presidential election. Only a president and a legitimate government can secure the future of the country where this resource, directly and indirectly, provides about 98% of the country’s foreign exchange resources. Some company executives fear that a new president would challenge this law, which would be passed by a transitional government, responsible for current affairs, while legal stability is a golden rule for all investor.

-Fifth: to answer this second question directly, the positive impact of this law would depend on the future global energy map, the entry of new producers and the sale price on the world market both of oil and gas returning at the cost of production in Algeria therefore to a new strategic management of SONATRACH and the impacts would not be felt only in three to four years, subject to the lifting of environmental constraints. Why this haste, which risks further sharpening social tensions in the run-up to the presidential election, thus possibly harming the voting turnout?

Saudi Aramco aims to announce the start of its initial public offering

Saudi Aramco aims to announce the start of its initial public offering

Hadeel Al SayeghDavide BarbusciaSaeed Azhar elaborate on how Saudi Aramco aims to begin planned IPO on Nov. 3: sources at a time where disinvestment in fossil fuels is taking off worldwide.

DUBAI/RIYADH (Reuters) – Saudi Aramco aims to announce the start of its initial public offering (IPO) on Nov. 3, three people with direct knowledge of the matter told Reuters, after delaying the deal earlier this month to give advisers time to secure cornerstone investors.

The people also said Aramco’s chief executive officer, Amin Nasser, was not present at the conference on Tuesday as he was meeting investors abroad ahead of the offering.

Aramco is looking to float a 1% to 2% stake on the kingdom’s Tadawul market, in what would be one of the largest ever public offerings, worth upwards of $20 billion.

Aramco, in response to queries by Reuters, said on Tuesday the oil company “does not comment on rumour or speculation. The company continues to engage with the shareholders on IPO readiness activities. The company is ready and timing will depend on market conditions and be at a time of the shareholders’ choosing.”

The people declined to be identified due to commercial sensitivities.

The company will soon have more shareholders from institutions, the head of the kingdom’s sovereign wealth fund, Yassir al-Rumayyan, said.

Al-Rumayyan, governor of the Public Investment Fund (PIF) and chairman of Aramco’s board of directors, was speaking at a panel at the conference in Riyadh.

Aramco will start subscription for investors in its initial public offering on Dec. 4, Saudi-owned news channel Al-Arabiya said in a news flash on Tuesday citing sources.

The oil giant plans to announce the transaction’s price on Nov. 17, it added. The company will begin trading on the local stock market, the Tadawul, on Dec. 11, the broadcaster reported.

The prospect of Aramco selling a piece of itself has had Wall Street on tenterhooks since Crown Prince Mohammed bin Salman first flagged it three years ago.

However, his desired $2 trillion valuation has always been questioned by some financiers and industry experts, who note that countries have been accelerating efforts to shift away from fossil fuels to curb global warming, putting oil prices under pressure and undermining producers’ equity value.

Russia’s sovereign wealth fund, the Russian Direct Investment Fund (RDIF), is working on a consortium of investors for Aramco’s IPO, its chief executive said.

“There are several Russian pensions funds who are interested to invest in the Aramco IPO and we have also received indications from our Russia-China fund of some Chinese major institutions also interested in Aramco IPO,” Russian Direct Investment Fund (RDIF) head Kirill Dmitriev told reporters on Tuesday.

Separately, Aramco has not approached the Kuwait Investment Authority (KIA) to invest in the IPO, the sovereign wealth fund’s managing director Farouk Bastaki said on Tuesday.

“KIA has not been approached by Aramco or its advisers for the IPO, and KIA will look at the IPO like any other investment,” Bastaki told reporters on the sidelines of an investment conference in Riyadh.

Electric cars are here – but we’ll still need fuel for a long time

Electric cars are here – but we’ll still need fuel for a long time

David Reiner, Cambridge Judge Business School and Ilkka Hannula, University of Cambridge, say that Electric cars are here – but we’ll still need fuel for a long time.

An interesting interval notably for all those industries already devoting billions of Dollars to building these E-cars, thus affecting not only the whole world’s manufacturing and energy generation industries alike but also the planet’s climate. But this obviously not happening overnight, is somehow phased as described in this article.

Many vehicles can’t just be powered by battery. MuchMania/Shutterstock

Electric cars are often seen as one of the great hopes for tackling climate change. With new models arriving in showrooms, major carmakers retooling for an electric future, and a small but growing number of consumers eager to convert from gas guzzlers, EVs appear to offer a way for us to decarbonise with little change to our way of life.

Yet there is a danger that fixating on electric cars leaves a large blind spot. Electrification would be very expensive for the lumbering lorries that haul goods across continents or is currently technically prohibitive for long-distance air travel.

Beyond all the enthusiasm surrounding electrification, currently light-duty passenger vehicles only comprise 50% of total global demand for energy in the transportation sector compared to 28% for heavy road vehicles, 10% for air, 9% for sea and 2% for rail.

Put simply, the current focus on electrifying passenger vehicles – though welcome – represents only part of the answer. For most other segments, fuels will be needed for the foreseeable future. And even for cars, electric vehicles are not a cure-all.

The unfortunate truth is that, on their own, battery electric vehicles (BEVs) cannot solve what we call the “100 EJ problem”. Demand for transport services are expected to rise dramatically in the coming decades. So the International Energy Agency (IEA) projects that we need to significantly reduce the amount of energy each vehicle uses just to keep total global energy demand in the transport sector roughly flat at current levels of 100 exajoules (EJ) by 2050. More than half of that 100 EJ is still expected to come from petroleum products and, by then, the share of light-duty vehicles in transport sector energy demand is expected to decline from 50% to 34%.

The vast majority of existing passenger trips can be accommodated by existing battery electric vehicles so, for many consumers, buying one will be an easy decision (as costs come down). But for those who frequently take very long journeys, the focus also needs to be on lower-carbon fuels.

Petroleum substitutes could extend sustainable transport to heavier vehicles and those seeking longer range, while using the existing refuelling infrastructure and vehicle fleet. Whereas battery electric vehicles will impose wider system costs (for example, the charging infrastructure needed to connect millions of new electric vehicles to the grid), all the transition costs of sustainable fuel substitutes are in the fuels themselves.

Our recent study is part of a renewed focus on synthetic fuels or synfuels (fuels converted from feedstocks other than petroleum). Synfuels were first made on an industrial scale in the 1920s by turning coal into liquid hydrocarbons using the so-called Fischer-Tropsch synthesis, named after its original German inventors. But using coal as a feedstock produces far dirtier fuel than even conventional petroleum-based fuels.

One possible route to carbon-neutral synthetic fuels would be to use woody residues and wastes as feedstock to create synthetic biofuels with less impact on the environment and food production than crop-based biofuels. Another option would be to produce synfuels from CO₂ and water using low-carbon electricity. But producing such “electrofuels” would need either a power system that is very low cost and ultra-low-carbon (such as those of Iceland or Quebec) or require dedicated sources of zero-carbon electricity that have high availability throughout the year.

Pilot plants

Synthetic biofuels and electrofuels both have the potential to deliver sustainable fuels at scale, but these efforts are still at the demonstration stage. Audi opened a €20M e-gas (electro fuel) plant in 2013 that produces 3.2 MW of synthetic methane from 6 MW of electricity. The €150M Swedish GoBiGas plant was commissioned in 2014 and produced synthetic biomethane at a scale of 20 MW using 30 MW of biomass.

Despite the many virtues of carbon-neutral synthetic fuels though, most commercial-scale projects are currently on hold. This is due to the high investment cost of pioneer process plants combined with a lack of sufficiently strong government policies to make them economically viable and share the risk of scale-up.

Government and industry attempts to encourage people to buy electric vehicles aren’t a problem in themselves. Our concern is that an exclusive focus on electrification may make solving the 100 EJ problem impossible. It is too early to tell which, if any, sustainable fuels will emerge successful and so the most pressing need is to scale up production from the current demonstration stage. If not, when our attention finally turns away from glossy electric car advertisements in a few years, we will find ourselves at a standing start in addressing the rest of the problem.

Reducing Carbon emissions and conserving Hydrocarbons

Reducing Carbon emissions and conserving Hydrocarbons

The key factors of all energy policies across the MENA are about reducing carbon emissions and conserving hydrocarbons reserves per this article, dated September 30, 2019, of Power Technology reporting (see below) on the latest World Energy Council’s congress of Abu Dhabi, early this month.

Clean energy steals the limelight at World Energy Congress

With an estimated $100bn-worth of renewables projects under study, design and in execution across the region, the policy momentum behind energy transformation is now being converted into new, potentially lucrative business opportunities across the Middle East and Africa.

Reducing carbon dioxide emissions and conserving hydrocarbons reserves are key factors shaping energy policy in the Middle East and North Africa (MENA).

But it is the more immediate combination of lower oil prices and the fall in the cost of renewable energy technologies that have seen every country in the region announce ambitious clean energy targets.

Clean energy, which includes renewables such as solar and wind power, as well as alternative fuels including waste-to-energy and nuclear, accounts for only a small proportion of electricity generation in the MENA region today.

Change is coming

According to the International Renewable Energy Agency (Irena), installed solar and wind capacity across the MENA region reached respectively 2,350MW and 434MW in 2017, up from just 91MW and 104MW in 2010.

And with an estimated $100bn-worth of renewables projects under study, design and in-execution across the region, the policy momentum behind energy transformation is now being converted into new, potentially lucrative business opportunities in the region.

Saudi shake-up

The significance of the region’s energy transition was clear to see at the latest edition of the World Energy Congress, which was hosted in Abu Dhabi in September.

Unsurprisingly, Saudi Arabia’s pavilion was the most-buzzing hive at the congress.

In addition to its broad programme of structural economic reforms and the recent appointment of a new energy minister, the region’s biggest economy has by far the most ambitious clean energy programme planned in the Middle East.

As Riyadh’s Renewable Energy Project Development Office (Repdo) outlined plans to launch tenders for its third round of its ambitious National Renewable Energy Programme (NREP) before the end of 2019, representatives from Saudi Arabia’s sovereign investment wealth fund, the Public Investment Fund (PIF), were meeting technology providers on the sidelines of the event to discuss the opportunities for building large-scale solar manufacturing facilities in the kingdom.

Emerging technologies

While solar and wind power are the main focus of the region’s energy diversification plans, some of the world’s largest energy companies were keen to showcase the potential for emerging technologies including waste-to-energy.

Another glimpse into the future was provided by discussions about the potential to store energy from peak-power sources such as solar and wind.

With the race to achieve cost-effective battery-storage solutions already underway, other technologies using hydrogen are being piloted in the region to offer another method to mitigate the intermittency issues of solar and wind power.

The challenge facing the region’s utilities is to convert their ambitious clean energy ambitions into actual investment projects.

Good economy helps with climate change

Good economy helps with climate change

BREAKINGVIEWS of September 25, 2019, post by Edward Hadas holds that Good economy helps with climate change, adding that “In many dimensions, the overall global economic situation is better than it has ever been.”

16-year-old Swedish Climate activist Greta Thunberg departs after speaking at the 2019 United Nations Climate Action Summit at U.N. headquarters in New York City, New York, U.S., September 23, 2019.

LONDON (Reuters Breakingviews) – Climate change is an urgent concern for heads of state gathering at the General Assembly of the United Nations this week. As young climate activists such as Greta Thunberg have made clear, this challenge will outlast the political lives of everyone gathered in New York. It is easy to become gloomy, but economists can bring some comfort. Three positive trends can help the world tackle man-made warming.16-year-old Swedish Climate activist Greta Thunberg departs after speaking at the 2019 United Nations Climate Action Summit at U.N. headquarters in New York City, New York, U.S., September 23, 2019.

The first is rising prosperity. In many dimensions, the overall global economic situation is better than it has ever been. Take life expectancy. This is a basic index of prosperity because longer lives are a sign of the availability of many of modern life’s essential goods and services.

The news is good. Globally, infants born in 2015 can on average expect to live for 71.7 years. That’s 6.6 years longer than those born two decades earlier, according to Our World in Data, which aggregates the latest available numbers. The gains have been largest in poorer countries. Life expectancy has risen by 8.3 years in India and 15.7 years in Ethiopia, compared with four years in Japan and a 2.8-year gain in the United States.

The spread of more comfortable lifestyles in the poorer parts of the world not only leads to longer lives. It also typically adds to the climate challenge, since increased prosperity tends to require the emission of more climate-warming greenhouse gases.

However, more educated, healthier and richer people living in societies with more economic resources are also much better equipped to cope with the difficulties caused by warming. The average number of annual deaths worldwide caused by natural disasters has been lower this decade than in the 1970s, according to Our World in Data, even though the global population is almost twice the size.

The resilience matters, because the world has not yet found any technically and politically plausible way to do much more than gradually slow the rate of warming. The wait for breakthroughs will be a lot less painful if people have the resources needed to change agricultural practices or move to more suitable places.

The second comforting economic trend is technological. The world has not lost its inventive momentum, despite dire predictions from economists such as Robert Gordon of Northwestern University. The most recent successes involve telecommunications. Our World in Data reports that since 2000, the number of internet users in the world has risen from 413 million to 3.4 billion. Penetration of mobile phones has increased from 12% of the world’s population to 104% over those years.

These revolutions required developments in the relatively new field of electronic engineering. The challenges of climate change require a revision of older technologies, particularly energy production and storage. The scientists, industrialists and planners seem to be coming up with the goods. Solar and wind power are becoming viable economic alternatives for coal-fired and gas-fired plants, while batteries are becoming efficient enough for electric-powered cars to become a big business.

Even with these breakthroughs, the global use of greenhouse-gas emitting hydrocarbons is very unlikely to decline quickly, because the world still relies so much on these energy sources. They accounted for 93% of energy production in 2016, and their use had increased a 1.4% annual rate in the preceding decade, according to Our World in Data.

Engineers, industrialists and governments can work together to reverse this trend. They can also explore carbon capture and other more exotic ways to manipulate the atmosphere. Despite the pervasive pessimism, the historical record suggests that the chances of success are high.

The third economic support is that the population boom is coming to an end. The number of people in the world is 4.7 times higher than in 1900, but women now have an average of 2.5 children. That is not far above the 2.1 at which the population would eventually stabilise.

Actual stability requires the high birth rates which are still prevalent in sub-Saharan Africa to follow the global pattern of falling as prosperity rises. Ethiopia is a good example of how fast things can change. The average woman there had seven children 20 years ago. Now she can expect 4.3.

The downward demographic shift raises various problems, such as funding retirements. For climate change, however, it is an unmitigated positive. Slower population growth leads to fewer energy users and less energy-intensive expenditure on new housing and its related infrastructure.

These economic trends will help the fight against climate change. Unfortunately, there is one necessary and powerful economic force which is not pointing clearly in the right direction.

Governments have to play the central role in organising the response to climate change. Only the political authorities have the scale and clout needed to mobilise existing economic resources and create new ones around the world.

The clout is there, but the will often seems to be weak. The contrast between the earnest and ambitious enthusiasm of the young climate action protesters and the cynical platitudes of many of the political leaders gathered in New York is striking. Economists can line up with the new generation.

Ethiopia again rejects Egypt’s vision for Renaissance Dam

Ethiopia again rejects Egypt’s vision for Renaissance Dam

EGYPT PULSE of Al-Monitor of September 24, 2019, reports that Ethiopia again rejects Egypt’s vision for Renaissance Dam. It is written by Ayah Aman. In the article summary, the author explains how “After more than a year of stalled negotiations between Egypt and Ethiopia on the Grand Ethiopian Renaissance Dam, Egypt’s diplomatic moves at the regional and international levels seem to have led nowhere.”

REUTERS/Tiksa Negeri/FilesEthiopia’s Grand Renaissance Dam seen under construction during a media tour, Guba Woreda, Ethiopia, March 31, 2015.

CAIRO — Egypt has initiated several international diplomatic moves expressing its deep concern about what it says is Ethiopia’s stalling and failure to reach a comprehensive agreement on filling and operating the Grand Ethiopian Renaissance Dam (GERD), which it sees as a threat to its water supply.

This comes after a year and four months’ lull in negotiations, since Ethiopian Prime Minister Abiy Ahmed visited Cairo in June 2018 and repeated after President Abdel Fattah al-Sisi the famous oath, “I swear to God, we will not cause any harm to Egypt’s Nile water.”

Technical, political and security negotiation rounds have been taking place for more than four years now, since the presidents of Egypt, Sudan and Ethiopia signed the Declaration of Principles in March 2015. At the time, the declaration was seen as a breakthrough in the crisis, which continues to go unresolved. Since then, Sisi has made many statements seeking to allay the Egyptian public’s fears about the dam. In January 2018, he announced the crisis with Ethiopia was over and said there were several paths to a solution.

Yet just this month, on Sept. 14, his statements at the annual National Youth Conference were alarming. Speaking of the dam construction that started in 2011, Sisi said Egypt has been “paying since 2011 for one mistake … a price we’ve paid and will continue to pay.” He asserted, “Dams would not have been built on the River Nile … was it not for 2011,” in reference to the January 2011 Revolution.

ALSO READ: OIL AND GASDoes Russia benefit from the Abqaiq attack?

Responding to a question concerning the dam at the “Ask the President” session held on the sidelines of the Youth Conference, Sisi recalled the Iraqi water shortage after the fall of the Iraqi state. He said, “Iraq in 1990 received 100 billion cubic meters (bcm) of water, but now it only receives 30 bcm.”

In early September, Egypt had launched official diplomatic efforts with other countries.

Foreign Minister Sameh Shoukry briefed foreign ministers attending a Sept. 10 Arab League meeting in Cairo on the difficulties marring the dam negotiations. He said Ethiopia has been inflexible recently and has even attempted to manipulate the situation. Arab League Secretary-General Ahmed Aboul Gheit said at a press conference that day that the Arab ministers had expressed solidarity in protecting Egypt’s water supply, which they agree is an integral part of overall Arab security.

As well, during a Sept. 12 meeting with ambassadors of European countries to Cairo, Egyptian Deputy Foreign Minister for African Affairs Ambassador Hamdi Loza briefed them on the latest developments regarding the dam and stressed Egypt’s uneasiness over the extended length of negotiations. A statement by the ministry after the meeting said Ethiopia has demonstrated “an insistence to impose a unilateral vision while disregarding the interests of others’ interests and without giving due diligence to avoiding damages to two estuary countries, especially Egypt, which depends on the Nile as the lifeblood of the Egyptian people.”

After a round of technical negotiations, Sept. 15-16 with Sudan in Cairo, Ethiopia and Egypt remain at odds.

Despite Egypt’s diplomatic mobilization ahead of the meeting, Ethiopia did not respond to any diplomatic pressure to approve or even discuss the Egyptian vision. Egypt had proposed filling the dam’s reservoir within seven years and releasing 40 bcm of Nile water annually to downstream countries.

Ethiopian Minister of Water and Energy Seleshi Bekele voiced his country’s rejection of Egypt’s requests. Ethiopian news website Addis Standard cited a classified document outlining Ethiopia’s rebuke of Egypt’s proposals. The Egyptian vision would “prolong the filling of GERD indefinitely” and “compensate for the Egyptian water deficit by serving as a second backup reservoir to High Aswan Dam,” according to the document. Egypt’s plan would mean the dam wouldn’t “deliver its economic return to Ethiopia … [and would] infringe on Ethiopia’s sovereignty.”

The document added, “Ethiopia [would] forfeit its rights to equitable and reasonable utilization of the Blue Nile water resources.”

Shoukry summarized Egypt’s position in dealing with the dam crisis by not yielding to the de facto policy that Ethiopia has been imposing since 2011. In remarks at a press conference Sept. 15, he said, “The will of one party will not be imposed by creating a concrete situation that is not being dealt with within the framework of consultation and understanding.”

Days later, Shoukry spoke about the dam in an exclusive, wide-ranging interview Sept. 21 with Al-Monitor at the United Nations in New York, where he emphasized the “life and death” nature of the negotiations. “I don’t think anybody would agree that the Ethiopian development should come at the expense of the lives of Egyptians,” he said.

A diplomatic official familiar with the Renaissance Dam negotiations told Al-Monitor in a telephone interview, “The continued stumbling of the negotiations and the failure of commitment or implementation of any of the items of the agreements reached in the previous meetings at the political, technical and security levels have become a source of grave concern. It’s not easy, but the Egyptian negotiators have offered many solutions and middle ground visions to achieve the best interest of all parties by filling the dam reservoir in a way that doesn’t harm Egypt and benefits Ethiopia.”

The official, who spoke on condition of anonymity given the sensitivity of this topic, added, “Egypt [gave up] many of its demands so as not to disrupt the course of negotiations, such as the World Bank intervention, which Ethiopia had rejected. Cairo has been dealing in good faith with all proposed visions and solutions, but the continued Ethiopian refusal, without offering any realistic alternative that reduces the risk of damages caused by the dam filling and operation, makes it difficult for negotiators to work [and] is a mere waste of time.”

The source went on, “Egypt will knock on all doors and use all international and regional diplomatic methods to guide the Ethiopian side to find a serious and comprehensive agreement on the filling, operation and management of the dam to safeguard the interests of the three parties (Egypt, Sudan and Ethiopia) and make the dam damage tolerable.”

Regarding the preliminary results of Egypt’s international efforts, the source sees a strong understanding and support at the Arab and European levels for Egypt’s concerns. “Egypt will take other measures in other international forums, including the United Nations General Assembly meetings,” said the source.

The water ministers of the three countries will meet again Oct. 4-5 to again discuss terms of the agreement on filling and operating the dam.

Don’t bet on the UN to fix climate change

Don’t bet on the UN to fix climate change

Marc Hudson, of University of Manchester in this article, says “Don’t bet on the UN to fix climate change – it’s failed for 30 years.” We would like to think that this is some sort of a gentle form of a warning that things ought not to be left to the United Nations alone to sort out, but up to us all, each in its own specific situation to contribute.

For instance, the UN chief calls for ‘concrete plans’ as climate emergency summit convenes in New York today.

We’re constantly encouraged to think of the next big climate summit, conference or protest as the most important one, the one that is about to make the all-important breakthrough. The UN’s Climate Action Summit on September 23 in New York is no different. The UN’s Secretary General António Guterres is calling on world leaders to come with concrete and realistic plans to bring their national net carbon emissions down to zero by 2050.

But amid the hype, it’s worth putting this UN summit in context against the history of 30 years of such international meetings. Is it a vain hope for 197 countries to agree on any meaningful climate action at all, especially when it involves so much money and power?

Scientists knew from the late 1950s that carbon dioxide was building up and that this could be a problem. By the late 1970s, they knew it would be – it was just a question of when. By 1985, at a workshop of scientists in Villach, Austria, the answer became “sooner than we thought”.

Scientists and activists mobilised and in 1988 the stars aligned. An American drought, a NASA scientist called James Hansen willing to stick his neck out and an international conference in Toronto meant politicians had to respond.

On the 1988 American presidential campaign trail, George Bush Senior promised to convene a global conference on the environment at the White House to “talk about global warming”. But when it finally happened it wasn’t truly global.

The Intergovernmental Panel on Climate Change (IPCC) was born the same year, endorsed by the UN general assembly, and produced its first report in 1990. By then, there had been fine declarations of motherhood-and-apple-pie in various European cities, such as the Hague and Bergen. However, negotiations towards an international treaty to do something about climate change itself did not begin until February 1991. The world’s media largely ignored them, as the 1991 Gulf War was underway.

UNFCCC birth pangs

Very little progress was made – a sign of things to come – and with a hard deadline of May 1992 approaching, a month before the world’s nations were to gather in Rio de Janeiro for an “Earth Summit”, powerful countries were at loggerheads.

The birth pangs of this search for an international UN treaty on climate change still shape what is and isn’t possible today.

The sticking point was – and still is – what the US government, and the business lobbies behind it, would find acceptable. The French government was keen that any treaty include actual commitments to reduce CO2 emissions, with targets and timetables for the rich nations. The Bush government warned that if these were included in the text they would not attend the Rio summit, leaving any treaty languishing. The French blinked, the UK acted as a middleman, and a deal was done.

The UN Framework Convention on Climate Change (UNFCCC) became law in March 1994, two years after the Rio summit.

The French, and others, had hoped that once the UNFCCC was signed and ratified, they could quickly address the question of rich country commitments to reduce CO2 emissions. But this didn’t happen.

When the Kyoto Protocol, which extended the UNFCCC, was agreed in 1997, despite the fact that carbon trading and other economic instruments within it were designed to keep the Americans happy, no serious commitment to reductions was made. The Americans then pulled out of the implementation process of the Kyoto Protocol in 2001, when George W Bush became president.

The process staggered on and there was another helping of motherhood-and-apple-pie at Copenhagen in 2009. Finally, in 2015 a non-binding Paris Agreement was cobbled together, based on a previously discarded “pledge and review” mechanism, which has created an endless round of promises that haven’t been met.

The scientist who had warned that climate change was upon us in 1988 – James Hansen – called the Paris Agreement a fraud, and since 2015, many nations are failing to meet their Paris commitments. Even if they did, global average temperature rise this century would be far in excess of the two degrees above pre-industrial levels that the deal is supposed to ensure.

The US pulled out of the Paris agreement in June 2017. A clear pattern has emerged.

The role of the UN

Some would argue that trying to get 197 countries to agree on anything is a fool’s errand. For 20 years, critics such as the international relations expert David Victor have questioned whether the UN is the appropriate venue for climate negotiations. Victor argues that such a forum is inevitably going to lead to gridlock. He’s not alone in this – as early as 1983 some policy analysts in the US were saying that such a global problem could not be solved because of the complexity of its politics.

The counter argument is that if a deal is agreed outside of the UN process, between the world’s major emitters – the EU, US and China – then it will be perceived as illegitimate, and will likely involve an even greater reliance on speculative technologies than the current Paris Agreement.

Ultimately, it becomes a matter of trust: do those already suffering the impacts of climate change trust those who have caused it to sort it out.

In my experience of talking to people who work in and around the UNFCCC’s bodies, many speak knowledgeably without hesitation, deviation or repetition about the alphabet soup of climate change acronyms, but are completely oblivious of much of this awkward history. Yet what happened – straightforward veto power by the US of anything that would look like real action – remains with us today, and it doesn’t help to pretend otherwise.

Whether the world can a transition to sustainability – the stated aims of both the UNFCCC and the UN’s Sustainable Development Goals – remains to be seen. But the stakes could not be higher. If political, economic, technological and cultural solutions aren’t now found, the outlook for humanity – and the other species we share this planet with – is exceptionally bleak.

Energy transition the buzzword, but a fossil future from the Gulf by ET Energy World

Energy ‘transition’ the buzzword, but a fossil future for the Gulf.

ABU DHABI, September 15, 2019  — In the vast air-conditioned halls of an Abu Dhabi conference centre, the world’s much-vaunted transition to clean energy is the buzzword in sessions of a top industry gathering.

But many executives and officials from oil-dependent Gulf states insist that while the change to renewables is essential, fossil fuels remain the future at least for the next few decades, despite the urgent need to fight climate change.

The debate has taken centre stage at this week’s World Energy Congress, with many officials calling for accelerating the process of moving to clean power sources and minimising carbon emissions.

Speakers addressed issues like the role of nuclear, hydrogen gas and other non-conventional sources of energy as a replacement for fossil fuels which currently account for over three-quarters of the world’s energy consumption.

However, delegates from oil-producing countries and particularly those in the Gulf argued that although the transition to clean energy sources must be supported, they will not be able to meet rising demand any time soon.

“For decades to come the world will still rely on oil and gas as the majority source of energy,” said the head of Abu Dhabi Oil Co. Jaber Sultan.

“About $11 trillion of investment in oil and gas is needed to keep up with current projected demand,” over the next two decades, he told the congress which was attended by representatives of 150 nations and over 400 CEOs.

Energy from increasingly competitive renewable sources has quadrupled globally in just a decade, but insatiable demand for energy particularly from developing economies saw power sector emissions rise 10 per cent, a UN report said last week. 

“All energy transitions — including this one — take decades, with many challenges along the road,” the CEO of Saudi energy giant Aramco, Amin Nasser, said at the conference.

Nasser said his country supports the growing contribution of alternatives, but criticised policies adopted by many governments that do not consider “the long-term nature of our business and the need for orderly transition”.

Addicted to oil 

Oil is still the lifeline for the Gulf states, contributing at least 70 per cent of national revenues across the region which has been cushioned by decades of immense profits from the flow of “black gold”.

Gulf nations have invested tens of billions of dollars in clean energy projects, mainly in solar and nuclear.

Dubai has launched the world’s largest solar energy project, with a price tag of $13.6 billion and the capacity to satisfy a quarter of the energy-hungry emirate’s current needs when it comes online in 2030.

But critics say the addiction to oil is a tough one to kick, particularly when supplies remain abundant and the massive investment in infrastructure necessary to switch to renewables is daunting.

“A global shift from dirty fossil fuel to renewable energy is economically, technically and technologically feasible… All that is missing is political will!” said Julien Jreissati from Greenpeace in the Middle East.

He said while the United Arab Emirates has put plans into action, “Saudi Arabia which has always made big announcements regarding their renewable energy ambitions is lagging behind as their projects and targets remain ink on paper.’

“There is no doubt that the world will leave oil behind. The only question remaining is when will this happen?”

Despite important technological advances made in the past decade, renewable energy sources still make up just around 18 per cent and nuclear adds another 6 per cent of the world’s energy mix. 

In the past decade, the adoption of wind and solar energy picked up rapidly as the production cost plummeted to levels close to that of oil and gas.

But the Abu Dhabi conference saw calls for accelerated innovation and “disruptive” technology to speed the transition as the world prepares for global energy demand to peak between 2020 and 2025, according to the World Energy Council.

Estonian President Kersti Kaljulaid said that sustainable and environmentally friendly energy practices must be aligned with national and global economic policies in order to have the required impact.

“It makes more economic sense to apply all green technologies globally, and if this happens we might go to being CO2-free energy users 5 or 10 or 20 years quicker,” she told the conference.

“I prefer that market forces, pushed by smart policymaking and legal space-setting, act quickly and save us all from the alternative.”
