This half-day strategic workshop, organized by Chatham House and E3G, brought together key climate experts, policymakers and influential actors, especially in Europe, for a focused and facilitated discussion on the roles, risks and potentials of negative emissions technologies (NETs). 

An interactive scenario exercise will be conducted, drawing on a climate simulation tool developed by Climate Interactive, to consider the potential roles and risks of different NETs deployments to meet the Paris Agreement targets and to consider the international co-operation required to manage the pathway to net-zero emissions. Participants will explore the political opportunities, discuss different scenarios and risks and identify areas of interventions and collective action.

The meeting is part of a series of events being held at Chatham House as part of London Climate Action Week (LCAW).

In recent years, clean energy access for refugees and internally displaced people has emerged as a potential method of improving humanitarian outcomes and enabling self-reliance. While recent research emphasizes the need for more quantitative data to inform energy access interventions, better qualitative understanding would also improve innovation in this area.

This ethnographic study is the first of its kind to analyse energy access and resilience strategies deployed in two refugee camps, Kakuma in Kenya and Goudoubo in Burkina Faso. The stories of residents in these camps demonstrate the importance of considering everyday experiences of displaced people in developing sustainable humanitarian energy interventions.

This paper highlights the need for new methodological approaches to expand the evidence base for humanitarian energy interventions and policies. Future research could usefully inform humanitarian energy projects by examining the technical knowledge and existing practices of refugees in the design of energy technologies, systems and business models. Uptake and sustained use of new systems may be more likely where interventions build on or work in harmony with these factors.

Mass human displacement crises like those in Syria, Democratic Republic of Congo and Myanmar do not dissipate within a year or two. The average age of a refugee camp globally is 18 and counting.

Meanwhile, the pressures on resources and services in neighbouring countries absorbing an influx of vulnerable people can be harsh. Imagine the overstressed schools and hospitals where intake has doubled in areas of Jordan and Lebanon, and the damage to ecosystems and elephant habitats where camps have sprung up in Bangladesh. 

The fallout from such crises is prompting new ways of working in the international humanitarian system. These recognize that short-term, emergency responses can jeopardize national development goals if maintained indefinitely. In most refugee camps for instance, each family cooks with wood in regions already suffering from deforestation.

Reliance on polluting trucks to bring in fuel and water is high. At the same time, developing countries – which host 80 per cent of the record 70.8 million people currently displaced by conflict – desperately need to address health, water, energy and housing needs for their own populations. Aid and welfare interventions directed only at refugees can provoke frustrations amongst the local community, damaging social cohesion and fostering political instability. 

The Global Compact on Refugees, affirmed by the United Nations General Assembly one year ago, aims at fairer responsibility-sharing amongst countries and equitable resourcing to host communities and refugees. The Global Refugee Forum (GRF) taking place 17–18 December in Geneva is the starting point for donor pledges and commitments. 

An opportunity for refugee-hosting countries

Among the GRF’s 6 focus themes is ‘Energy and Infrastructure’ – a new priority for humanitarian aid and finance. This covers energy, environment, water and sanitation, health, shelter and connectivity – services that are tightly interconnected. In October, the UN Refugee Agency (UNHCR) also launched its first energy strategy, which ‘promotes the transition to clean, renewable energy at refugee camps and hosting sites’.

Given this impetus, alongside a growing international focus on speeding up Sustainable Development Goal (SDG) delivery, stabilizing migration and supporting climate resilience, more aid and soft credit for interlinked objectives will become available. Countries hosting refugees have an opportunity; how they approach it will determine the level of support they attract and how effectively it is deployed. 

Policy conditions are key to success

In a refugee situation, energy access is about much more than keeping warm or cooking food. It is also about connecting with loved ones across borders, safety at night, healthy births and making a living. Due to the lack of long-term funding, maintenance systems or government approvals, failed pilots to introduce for example, solar streetlighting or clean cookstoves, are the norm. 

To increase their durability and reach, projects need to harness local markets and support national development goals, especially those on access to modern energy for all (SDG 7), protecting ecosystems (SDG 15) and resilient human settlements (SDG 11). Several examples of these are emerging, each with valuable lessons to share. 

The policy environment, in particular, coordination between authorities, humanitarian agencies and private sector actors, can make or break a project. Beyond the basic conditions of adequate security and refugee acceptance, our research highlights three enabling factors:

First: government willingness to engage in long-term response and resilience coordination. Jordan is the most advanced in this with its three-year rolling Response Plan for the Syria Crisis whereby the government works with humanitarian agencies to integrate refugee welfare with national development needs.

Here, energy, water and housing needs are specified and have attracted funding. For example, in Irbid, Jordan where over 137,600 Syrian refugees live, the Norwegian Refugee Council, is expanding a programme under the Renewable Energy for Refugees (RE4R) initiative that applies energy efficiency and solar water heating to reduce bills and rents for refugee tenants while adding value for Jordanian homeowners.   

Second: strong, clear, energy and environment plans and legislation. Signals can be mixed. Jordan’s ‘wheeling’ regulation, allowed UNHCR to reduce its electricity bills through specially built solar plants at Azraq and Zaatari, yet the current freeze on renewable connections has stifled further projects.

In Rwanda,  the government banned the supply of woodfuel to refugee camps on the basis of concerns about deforestation. The announcement sharpens focus on cleaner cooking.

Yet with little guidance on enforcement and the timeframe for change, it is difficult for UNHCR and its partners to plan viable schemes. A reversion to stove and fuel handouts is likely, damaging the potential to create markets for alternative cooking practices in the camps. 

Third: local fuel prices. Where polluting fuels are subsidized or untaxed, additional subsidy is needed to make cleaner alternatives competitive. The higher prices of diesel in Uganda for example are an incentive for solar projects at Bidi Bidi, the world’s largest refugee settlement.

The Gaia Association-UNHCR clean energy programme in Ethiopia’s Western refugee camps has avoided burning some 10,000 tonnes of wood since 2006 through ethanol, but if  VAT (which is applied to neither charcoal nor kerosene) were waived, it could scale up commercially. 

Joining up the dots

Many humanitarian and government dots could be joined up in support of the SDGs. In Rwanda for example, clarity on electrification plans – which appear to cover refugee areas – could allow camp mini-grids to be designed for eventual grid integration. In Jordan, lessons learned from the home upgrading programme could be applied to meet city climate resilience ambitions. 

Donors at the GRF should support humanitarian operations that leave a positive legacy, increasing the robustness of country infrastructure and systems. Host-country governments should help define and encourage projects that benefit national and refugee populations. This will be critical to both development outcomes and limiting future human suffering. 

The seventh annual meeting of the New Petroleum Producers Discussion Group brings together people from the group's member countries. The meeting includes an international discussion, a national seminar and a range of policy-relevant courses which have been specially tailored to the priorities of the group. This year’s international discussion focused on ‘Building Capacity and Institutions’.

The New Petroleum Producers Discussion Group was first established in 2012 and provides a unique forum which brings together governments from over 30 new and prospective oil and gas producers to share their ideas and experiences. The group is jointly coordinated by Chatham House, the Commonwealth Secretariat, and the Natural Resource Governance Institute (NRGI).

This event was hosted by the Ministry of Energy of Uganda.

The assassination of General Qassem Soleimani has created much speculation about the possible impact on oil markets and – although any impact will very much depend upon what happens next in terms of political and military responses – theoretically the potential exists for Iran to seriously destabilize oil markets, raising oil prices.

Arguably, it would be in Iran’s interest to do so. It would certainly hurt Trump’s possibility of a second term if higher prices were to last for some time as the 2020 presidential election gets underway. And it would also help shore up Iran’s failing economy. 

The assassination did initially cause oil prices to rise by a few dollars before quickly falling back, and the missile attacks by Iran produced a similar response. However, direct action by Iran to raise prices – for example by trying to close the Strait of Hormuz – is unlikely.

Around one-fifth of the world's oil supplies passes through the Strait of Hormuz, a narrow choke point between Iran and the Arabian Peninsula. Closing it would invite serious military action by the Americans and many of its allies who, so far, have been rather lukewarm over Trump’s actions. It would also possibly limit Iran’s own oil exports.

Similarly, overt attacks on American allies in the region such as Saudi Arabia and the UAE would probably invite too heavy a reaction, although this is uncertain given the lack of response after the alleged Iranian attacks on Abqaiq and Khurais in mid-September.

Indirect action by Iran to affect oil supplies is much more likely as they have many options by using their proxies to affect others’ oil production. This is especially true for Iraq, which is now an important source of global oil supply as Iraqi exports in 2019 averaged 3.53 million barrels per day (Mb/d), a significant amount.

Iraq’s future production has already been damaged as international oil companies are withdrawing staff for safety reasons, anticipating potential attacks by both Iraqi and Iranian sources. It is now very unlikely that the crucial ‘common seawater supply project’ being run by Exxon – essential for expanding production capacity – will go ahead in the near future.

However, one important consequence of the assassination that has attracted little attention is that it has almost fully restored the role of geopolitics into the determination of oil prices. Up to 2014, geopolitics played a key role in determining oil prices in the paper markets where perceptions and expectations ruled.

Prices determined in these markets – NYMEX in New York, ICE in London and other lesser futures markets throughout the world – then influence wet barrel markets where real barrels of oil are traded. 

In 2014, the world was so oversupplied with real oil barrels that the oil price collapsed – the price of Brent crude fell from $110.72 on 23 May to $46.44 eight months later. Thereafter, little if any attention was given to geopolitical events, and geopolitics became marginalized in the determination of crude oil prices.

This began to change in 2019. The market remained physically over-supplied but events in the Gulf began to attract attention. In June, there were a series of attacks on oil tankers close to the Gulf, followed by attacks on Saudi Arabia’s Abqaiq processing facility and the Khurais oil field in September.

The Americans claimed these attacks were launched by Iran, but no convincing evidence for the claim was provided. Both attacks produced an initial price response but it was surprisingly limited and short-lived. However, it did suggest that geopolitics might be creeping back into influencing oil prices.

This became ever more noticeable in the third and fourth quarters as rumours regarding the trade talks between China and US clearly began to affect price – talks going well meant higher oil demand, and prices rose; talks going badly meant lower oil demand, and prices fell.

Meanwhile, the oil market showed signs of tightening towards the end of 2019. Although there was much cheating on the OPEC+ agreement that was trying to restrain production and protect prices, the OPEC meeting last December saw both Iraq and Nigeria agreeing to restrain production. 

US stock levels also began to fall in December and the futures markets began to price in a tightening market towards the end of 2020. Significantly, the tighter the market appears, the greater attention is paid to the level of spare producing capacity.

Just before the attack on Abqaiq, the International Energy Agency (IEA) estimated there was 3.5 Mb/d spare capacity in OPEC which, historically, is quite comfortable. However, 2.5 of this was estimated to be in Saudi Arabia, so how much of this spare capacity still existed after the Abqaiq attack?

The Saudis claimed the Abqaiq capacity was quickly restored but technical experts greeted this with considerable skepticism, not least because the Abqaiq equipment was highly specialized. If spare capacity is tight, this makes the oil price vulnerable to geopolitical scares and rumours, real or imagined. 

Although the assassination of General Soleimani has exacerbated the sensitivity of oil markets to geopolitical events, this becomes irrelevant if a serious shooting war starts in the region. Saudi Arabia, the UAE and Iraq’s oil infrastructure remains highly vulnerable to attack either directly by Iran or one of its many proxies, suggesting oil prices will become increasingly volatile but, at the same time, benefit from a rising geopolitical premium.

The world is currently witnessing how vulnerable existing production and consumption systems are, with the current global health crisis harshly exposing the magnitude of the risks associated with the global economy in its current form, grounded, as it is, in a linear system that uses a ‘take–make–throw away’ approach.

These ‘linear risks’ associated with the existing global supply chain system are extremely high for national economies overly dependent on natural resource extraction and exports of commodities like minerals and metals. Equally vulnerable are countries with large manufacturing sectors of ready-made garments and non-repairable consumer goods for western markets. Furthermore, workers and communities working in these sectors are vulnerable to these changes as a result of disruptive technologies and reduced demand.

In a recently published Chatham House research paper, ‘Promoting a Just Transition to an Inclusive Circular Economy’, we highlight why a circular economy approach presents the world with a solution to old and new global risks – from marine plastic pollution to climate change and resource scarcity.

Taking the long view

So far, action to transition to a circular economy has been slow compared to the current crisis which has mobilized rapid global action. For proponents of transitioning to a circular economy, this requires taking the long view. The pandemic has shown us that global emergencies can fast-forward processes that otherwise might take years, even decades, to play out or reverse achievements which have taken years to accomplish.

In this vein, there are three striking points of convergence between the COVID-19 pandemic and the need to transition to an inclusive circular economy.

Firstly, the current crisis is a stark reminder that the circular economy is not only necessary to ensure long-term resource security but also short-term supplies of important materials. In many cities across the US, the UK and Europe, councils have suspended recycling to focus on essential waste collection services. The UK Recycling Association, for example, has warned about carboard shortages due to disrupted recycling operations with possible shortages for food and medicine packaging on the horizon.

Similarly, in China, most recycling sites were shut during the country’s lockdown presenting implications for global recycling markets with additional concerns that there will be a fibre shortage across Europe and possibly around the world.

Furthermore, worldwide COVID-19 lockdowns are resulting in a resurgence in the use of single-use packaging creating a new wave of plastic waste especially from food deliveries – already seen in China – with illegal waste fly-tipping dramatically increasing in the UK since the lockdown.

In this vein, concerns over the current global health crisis is reversing previous positive trends where many cities had established recycling schemes and companies and consumers had switched to reusable alternatives.

Secondly, the need to improve the working conditions of the people working in the informal circular economy, such as waste pickers and recyclers, is imperative. Many waste materials and recyclables that are being handled and collected may be contaminated as a result of being mixed with medical waste.

Now, more than ever, key workers in waste management, collection and recycling require personal protective equipment and social protection to ensure their safety as well as the continuation of essential waste collection so as not to increase the potential for new risks associated with additional infectious diseases.

In India, almost 450 million workers including construction workers, street vendors and landless agricultural labourers, work in the informal sector. In the current climate, the poorest who are unable to work pose a great risk to the Indian economy which could find itself having to shut down.

Moreover, many informal workers live in make-shift settlements areas such as Asia’s largest slum, Dharavi in Mumbai, where health authorities are now facing serious challenges to contain the spread of the disease. Lack of access to handwashing and sanitation facilities, however, further increase these risks but circular, decentralized solutions could make important contributions to sustainable sanitation, health and improved community resilience.

Thirdly, it is anticipated that in the long term several global supply chains will be radically changed as a result of transformed demand patterns and the increase in circular practices such as urban mining for the recovery and recycling of metals or the reuse and recycling of textile fibres and localized additive manufacturing (e.g. 3D printing).

Many of these supply chains and trade flows have now been already severely disrupted due to the COVID-19 pandemic. For example, the global garment industry has been particularly hard-hit due to the closure of outlets amid falling demand for apparel.

It is important to note, workers at the bottom of these garment supply chains are among the most vulnerable and most affected by the crisis as global fashion brands, for example, have been cancelling orders – in the order of $6 billion in the case of Bangladesh alone. Only after intense negotiations are some brands assuming financial responsibility in the form of compensation wage funds to help suppliers in Myanmar, Cambodia and Bangladesh to pay workers during the ongoing crisis.

In addition, the current pandemic is damaging demand for raw materials thereby affecting mining countries. Demand for Africa’s commodities in China, for example, has declined significantly, with the impact on African economies expected to be serious, with 15 per cent of the world’s copper and 20 per cent of the world’s zinc mines currently going offline. 

A further threat is expected to come from falling commodity prices as a result of the curtailment of manufacturing activity in China particularly for crude oil, copper, iron ore and other industrial commodities which, in these cases, will have direct impacts on the Australian and Canadian mining sectors.

This is all being compounded by an associated decline in consumer demand worldwide. For example, many South African mining companies – leading producers of metals and minerals – have started closing their mining operations following the government’s announcement of a lockdown in order to prevent the transmission of the virus among miners who often work in confined spaces and in close proximity with one another. As workers are laid off due to COVID-19, there are indications that the mining industry will see fast-tracking towards automated mining operations. 

All of these linear risks that have been exposed through the COVID-19 pandemic reinforce the need for a just transition to a circular economy. But while the reduction in the consumption of resources is necessary to achieve sustainability, the social impacts on low- and middle- income countries and their workers requires international support mechanisms.

In addition, the current situation also highlights the need to find a new approach to globalized retail chains and a balance between local and global trade based on international cooperation across global value chains rather than implementation of trade protectionist measures.

In this vein, all of the recovery plans from the global COVID-19 pandemic need to be aligned with the principles of an inclusive circular economy in order to ensure both short-term and long-term resilience and preparedness for future challenges and disruptions.  

Historically, Iraq lay claim to one of the most abundant water supplies in the Middle East. But the flow of the Tigris and Euphrates rivers has reduced by up to 40% since the 1970s, due in part to the actions of neighbouring countries, in particular Turkey, upstream.

Rising temperatures and reduced rainfall due to climate change are also negatively impacting Iraq’s water reserves. Evaporation from dams and reservoirs is estimated to lose the country up to 8 billion cubic metres of water every year.

A threat to peace and stability

Shortages have dried up previously fertile land, increasing poverty in agricultural areas. Shortages have also served to fuel conflict: communities faced with successive droughts and government inertia proved to be easy targets for ISIS recruiters, who lured farmers into joining them by offering money and food to feed their families. Economic hardship for those whose livelihoods relied upon river water has also driven rural to urban migration, putting significant strain on already over-populated towns and cities, exacerbating housing, job and electricity shortages, and widening the gap between haves and have-nots.

But scarcity isn’t the most crucial element of Iraq’s water crisis – contamination is. Decades of local government mismanagement, corrupt practices and a lack of regulation of dumping (it is estimated up to 70% of Iraq’s industrial waste is dumped directly into water) has left approximately three in every five citizens without a reliable source of potable water.

In 2018, 118,000 residents of Basra province were hospitalised with symptoms brought on by drinking contaminated water, which not only put a spotlight on the inadequacies of a crumbling healthcare system but sparked mass protests and a subsequent violent crackdown.

The water crisis is also undermining the stability of the country’s federal governance model, by occasionally sparking disputes between Baghdad and the Kurdistan Regional Government, as well as between governorates in the south.

The crisis is both a symptom and a cause of poor governance. Iraq is stuck in a cycle whereby government inaction causes shortages and contamination, which result in economic losses, reduced food supply, increased prices and widespread poor health. This in turn leads to increasing levels of poverty, higher demand on services and civil unrest, increasing the pressure on a weak, dysfunctional system of government.

What can be done?

The first priority should be modernising existing water-management infrastructure - a relic of a time when the problem was an excess rather than a shortage of water (the last time Iraq’s flood defences were required was 1968). Bureaucratic hurdles, widespread corruption and an endless cycle of other crises taking precedent prevent good initiatives from being implemented or scaled up.

Diversifying energy sources to improve provision is crucial. Baghdad has a sewage treatment plant that originally ran on its own electricity source, but this capacity was destroyed in 1991 and was never replaced. The city continues to suffer from dangerous levels of water pollution because the electricity supply from the grid is insufficient to power the plant. Solar energy has great potential in sun-drenched Iraq to bridge the gaping hole in energy provision, but successive governments have chosen to focus on fossil fuels rather than promoting investment to grow the renewables sector.

Heightened tension with upstream Turkey could turn water into another cause of regional conflict. But, if approached differently, collaboration between Iraq and its neighbour could foster regional harmony.

Turkey’s elevated geography and cooler climate mean its water reserves suffer 75% less evaporation than Iraq’s. Given that Turkey’s top energy priority is the diversification of its supply of imported hydrocarbons, a win-win deal could see Turkey exchange access to its water-management infrastructure for delivery of reduced cost energy supplies from Iraq.

German-French cooperation on coal and steel in the 1950s and the evolution of economic integration that followed might provide a model for how bilateral cooperation over one issue could result in cooperation with other regional players (in this case Iran and Syria) on a range of other issues. This kind of model would need to consider the future of energy, whereby oil and gas would be replaced by solar-power exports.

These solutions have been open to policymakers for years and yet they have taken little tangible action. While there are leaders and bureaucrats with the will to act, effective action is invariably blocked by a complex and opaque political system replete with vested interests in maintaining power and wealth via a weak state and limited services from central government.

Breaking the cycle

To break this cycle, Iraq needs a group of professional and able actors outside of government to work with willing elements of the state bureaucracy as a taskforce to pressure for action and accountability. Publishing the recommendations from a hitherto withheld report produced in the aftermath of Basra’s 2018 heath crisis would be a great start.

In time, this taskforce could champion the prioritisation of water on the national agenda, the implementation of infrastructure upgrades, and hold more productive conversations with neighbour states.

With such a high degree of state fragmentation and dysfunction in Iraq, looking to the central government to provide leadership will not yield results. Engagement with a coalition of non-state actors can begin to address the water crisis and also open a dialogue around new models of governance for other critical issues. This might even be a starting point for rewriting the tattered social contract in Iraq.

This piece is based on insights and discussion at a roundtable event, Conflict and the Water Crisis in Iraq, held at Chatham House on March 9 as part of the Iraq Initiative.

Avoiding the worst economic, social and environmental risks of climate change requires a better understanding of what those risks may be. Decision-makers need information on the full range of risks that climate change poses, across the full spectrum of probabilities. Monitoring the nature and severity of these risks is essential if decision-makers are to make the right choices about effective mitigation and adaptation responses.

To meet this need, international scientists and policy analysts in the UK (including at Chatham House) and China have been engaged in a multi-year, multi-disciplinary, and collaborative research process. This has deepened understandings of how these complex, interconnected first, second and third-order risks can be better assessed and tracked.

Phase one, culminating in 2015 and involving experts, demonstrated how general principles of risk assessment could be applied in relation to climate change.

Phase two (culminating in 2019) was a bilateral cooperation between the UK and China that was agreed during President Xi Jinping’s state visit to the UK in 2015. It addressed a specific recommendation from phase one - that risk assessments need to be made on a regular and consistent basis - by providing a proof of concept indicator framework.

Substantive project funding for phases 1 and 2 was provided by the UK Foreign and Commonwealth Office, with additional contributions and in-kind support from the China Expert Panel on Climate Change, the UK Government Office for Science, the Skoll Global Threats Fund, the Global Challenges Foundation, the UK Institute and Faculty of Actuaries, and Willis Research Network (phase 1); and Chatham House, China Expert Panel on Climate Change, UK Committee on Climate Change, International Energy Agency, Willis Towers Watson (phase 2).

Many institutions contributed to the project under phases 1 and 2 (see reports for full list of contributors).

• Phase 1 report, 2015: Climate Change: A Risk Assessment
• Phase 2 report, 2018: Developing Indicators of Climate Risk

Chatham House now leads a third phase of this project (2020 to 2022), funded by the Prosperity Fund of the UK Foreign and Commonwealth Office. The purpose is to help ensure emissions reduction and resilience strategies, policies and decision-making - both in China and globally - are better informed by an evidence-based perspective on climate-change risks.

Under the guidance of the China Expert Committee on Climate Change and the UK Committee on Climate Change, the programme is building on the risk indicator and risk assessment work developed in Phase 1 and 2.

This phase of work has four complementary workstreams looking at emissions risks, direct climate risks, systemic climate risks and the integration of climate risks into Chinese and international governance frameworks. Embedded throughout the project is considerations of gender and inclusion（G&I) which are fundamental to achieve climate-compatible development.

The programme is delivered through a cohort of partner organisations based in both China and the UK, including Chatham House, E3G (Third Generation Environmentalism), Hubei University of Economics, National Climate Centre of China, Tsinghua University and the University of Reading.

The pressure of the coronavirus pandemic is adding to a widely held misconception that trade in food products is bad for the environment due to the associated ‘food miles’ – the carbon footprint of agricultural products transported over long distances.

This concept, developed by large retailers a decade ago, is often invoked as a rationale for restricting trade and choosing locally-produced food over imports. Consuming local food may seem sensible at first glance as it reduces the carbon footprint of goods and generates local employment. 

However, this assumption ignores the emissions produced during the production, processing or storage stages which often dwarf transport emissions. Other avenues to address the climate change impact of trade are more promising.

Demystifying food emissions

In the US, for example, food items travel more than 8,000 km on average before reaching the consumer. Yet transport only accounts for 11 per cent of total emissions with 83 per cent – mostly nitrous oxide (N2O) and methane (CH4) emissions – occurring at the production stage.

US Department of Agriculture data on energy use in the American food system echoes this finding, showing that processing, packaging, and selling of food represent ten times the energy used to transport food.

In practice, it may be preferable from an environmental perspective to consume lamb, onion or dairy products transported by sea because the lower emissions generated at the production stage offset those resulting from transport. Similarly, growing tomatoes under heated greenhouses in Sweden is often more emissions-intensive than importing open-grown ones from Southern Europe.

Seasonality also matters. British apples placed in storage for ten months leads to twice the level of emissions as that of South American apples sea-freighted to the UK. And the type of transport is also important as, overall, maritime transport generates 25 to 250 times less emissions than trucks, and air freight generates on average five times more emissions than road transport.

Therefore, air-freighted Kenyan beans have a much larger carbon footprint than those produced in the UK, but crossing Europe by truck to import Italian wine might generate more emissions than transatlantic shipments.

Finally, one should take into account the last leg of transport. A consumer driving more than 10 km to purchase 1 kg of fresh produce will generate proportionately more greenhouse gas (GHG) emissions than air-freighting 1 kg of produce from Kenya.

Shifting consumption towards local foods may reduce GHG emissions in sectors with relatively low emissions intensities but, when non-carbon dioxide emissions are taken into account, this is more often the exception than the rule.

Under these circumstances, preventing trade is an inefficient and expensive way of reducing GHG emissions. Bureau et al. for example, calculate that a global tariff maintaining the volume of trade at current levels until 2030 may reduce global carbon dioxide emissions by 3.5 per cent. However, this would be roughly seven times less than the full implementation of the Paris Agreement and cost equivalent to the current GDP of Brazil or 1.8 per cent of world GDP.

By preventing an efficient use of resources, such restrictions would also undermine the role of trade in offsetting possible climate-induced production shortfalls in some parts of the world and allowing people to access food when they can’t produce it themselves.

Reducing the climate footprint of trade

This is not to say that nothing should be done to tackle transport emissions. The OECD estimates that international trade-related freight accounted for over 5 per cent of total global fuel emissions with shipping representing roughly half of it, trucks 40 per cent, air 6 per cent and rail 2 per cent. With the projected tripling of freight transport by 2050, emissions from shipping are expected to rise between 50 and 250 per cent.

Furthermore, because of their international nature, these emissions are not covered by the Paris Agreement. Instead the two UN agencies regulating these sectors – the International Civil Aviation Organization and the International Maritime Organization – are responsible for reducing these emissions and, so far, significant progress has proven elusive.

Regional or bilateral free trade agreements to further stimulate trade could address this problem by exploiting comparative advantages. Impact assessments of those agreements often point towards increases in GHG emissions due to a boost in trade flows. In the future, such agreements could incorporate – or develop in parallel – initiatives to ensure carbon neutrality by connecting carbon markets among contracting parties or by taxing international maritime and air transport emissions.

Such initiatives could be combined with providing additional preferences in the form of enhanced market access to low-carbon food and healthier food. The EU, as one of the chief proponents of bilateral and regional trade agreements and a leader in promoting a transition to a low-carbon economy could champion such an approach.
