Published by Friends of the Earth Europe, November 2017 INTRODUCTION In December 2015, in Paris, world leaders agreed once again to put a halt to climate change, as they had in Cancun, Copenhagen, Kyoto and Rio before that. This time, signatories committed to “holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels’’. 1 But despite these promises of climate action, the world remains on track for catastrophic global warming, with the United Nations Environment Programme (UNEP) warning that even if all the Paris pledges are kept, the world will still warm by more than 3°C.2 Central to this continuing failure to meet the challenge of climate change is the world’s relentless addiction to fossil fuels: coal, oil, and gas. The fossil fuel industry continues extracting and burning these hydrocarbons at unsustainable rates, and even persists in exploring for more. Yet there has been a shift in global energy politics: although many investments in coal and oil continue, there has been a significant turn towards gas. It is partly in response to climate policies, and to the influence of the shale gas boom in the United States (U.S.), that the oil and gas industry is investing more heavily in gas. Gas is widely predicted not only to be a mainstay of the global energy system, but to play an even greater role. The International Energy Agency predicts a 50% increase in gas demand by 2040.3 In the European Union (EU), gas is central to the so-called ‘Energy Union’ – the EU’s vision for Europe’s energy future.4 But is this emphasis on gas compatible with the goals of the Paris Agreement that the EU has endorsed? Is there a sufficient carbon budget to replace one fossil fuel with another? Should the EU continue to support a gas-filled future? And what will the consequences be if it does?
RISING TEMPERATURES, DEVASTATING IMPACTS Scientists have shown beyond doubt that a 2°C temperature rise cannot be considered Destruction of Typhoon Haiyan in 2013 in the ‘safe’. Such a temperature increase will have devastating consequences that will hit the Philippines, causing widespread damage and loss of life most vulnerable hardest. Even a 1.5°C rise in average global temperatures carries major Credit: Eoghan Rice - Trócaire risks, threatening the very existence of some small island nations and low-lying coastal regions. As no temperature rise is truly safe or acceptable, illustrated plainly by today’s extreme climate-related weather events, countries should aim for the lowest temperature increase. Last year, 2016, was the hottest year on record, with an average temperature 1.1°C above the pre-industrial era, while 16 of the 17 warmest years on record have occurred since the beginning of the 21st century.5 And this year has brought numerous stark reminders that the world is facing a climate emergency: floods in South Asia and storms in the Atlantic have shown once again the devastating impact of climate change on human lives and livelihoods, particularly on the poorest and most vulnerable. Europe experienced the ‘Lucifer heatwave’, which affected millions and saw temperatures as high as 42°C in Split, Croatia.6 Hurricanes Harvey and Irma (one of the strongest Atlantic storms on record) devastated large parts of the Caribbean, as well as showing that even the most developed countries are vulnerable to climate disasters.7
1 EUROPE’S CLIMATE MODELS RELY ON NEGATIVE EMISSIONS, AND CARBON CAPTURE CARBON BUDGET: A significant dimension to the current debate on carbon budgets is the existence in a number of key energy and climate scenarios of negative emissions technologies (NETS) and/or Bio-Energy Carbon Capture and Storage (BECCS). The effect of the inclusion of these unproven NO ROOM FOR GAS technologies is to enlarge the foreseen carbon budget available for fossil fuel emissions. According to Anderson and Broderick, “virtually all of the 2°C scenarios within the IPCC’s database include negative emissions technologies removing several billion tonnes of carbon THE WORLD’S CARBON dioxide directly from the atmosphere. However there is wide recognition that the efficacy and global rollout of such technologies are highly speculative, with a non-trivial risk of failing to BUDGET IS RUNNING OUT deliver at, or even approaching the scales typically assumed in the models.” “...there is The world continues to burn fossil fuels and to put ever more greenhouse gases The International Energy Agencies Energy Technologies Perspective (based on their Reference into the atmosphere, bringing us closer to yet greater climate disaster.

Since then, one quarter of that budget has already been used up.8 At the current rate of emissions, the world’s carbon budget for even a 2°C temperature rise will have run out in Relying on future negative emissions is both dangerous for the climate and those likely additional fossil to be affected by the use of such technologies in the future. BECCS, for example, is likely only 20 years.9 Much more urgent and effective climate actions are therefore needed before to lead to large scale negative social and environmental effects such as landgrabbing and 2020, to have a chance of meeting the commitments made at the Paris climate talks. biodiversity loss due to the sheer scale demanded of any enterprise to balance fossil fuel fuel reserves, Those with the greatest historical responsibility for climate change – the EU, the U.S. and emissions with biological offsets.

With the gas supply chain (and not only at the final combustion stage) that this in mind, Anderson and Broderick’s calculation of how long the EU climate and environmental impact can truly be measured. When taken But this level of commitment is insufficient to adequately reflect Europe’s responsibility and has, at current levels of emissions, before it surpasses its carbon as a whole, the greenhouse gas emissions at every stage from gas capability to tackle climate change. budget can be considered an optimistic scenario. exploration to gas consumption, combined with the environmental, According to a review by global civil society organisations, including Friends of the social and health impacts associated with gas extraction, make gas a Earth International, which evaluates fair shares of global mitigation efforts, the EU has a source of energy that is anything but clean and safe. responsibility for a much greater level of mitigation than is currently contained in its NDC.

In other words, climate justice requires the non-OECD mitigation pathways, Anderson and Broderick show that, ignoring all other emissions, the budget would run out by the middle EU to be doing nearly five times more to mitigate climate change. In order to determine by 2035, the EU will have to reduce its energy emissions, including of the century.19 whether there is still room for gas in Europe’s carbon budget, Friends of the Earth Europe from power generation, by 95% to be within Europe’s carbon budget Given that the EU is already producing far more CO than that just commissioned the Tyndall Centre at the University of Manchester and Teeside University for achieving no more than 2°C warming.

For a serious probability Broderick state, “there is categorically no role for bringing additional of staying within 1.5°C warming, an even faster phase out of all fossil own emissions. It is clear that achieving a lower temperature target would be an even more fossil fuel reserves, including gas, into production”. onerous challenge, though one that justice requires we do our utmost to meet. fuels will be needed. The conclusion that gas has no role in the EU’s energy system In order to develop their estimates, Anderson and Broderick looked at the capacity for derives from the fact that gas is a fossil fuel that emits substantial climate change mitigation in the global South within the global carbon budget for 2°C, and amounts of greenhouse gases. As Climate Action Tracker, an created several “highly ambitious” mitigation pathways for non-OECD country emissions, independent scientific analysis produced by three research based on their energy-based carbon emissions peaking between 2020 and 2025. organisations, has recently noted “emissions for power from unabated natural gas are incompatible with power sector decarbonisation: life- cycle emissions, i.e. taking into account the emissions in the fuel chain and the manufacturing of the energy conversion technology, 2 3 THE METHANE METHANE’S CLIMATE IMPACT Methane is a potent greenhouse gas, with a global warming potential 34 times higher than CO2 on a 100-year time horizon, and 86 times higher on a 20 year timeframe (IPCC AR5).23 Though PROBLEM: LEAKING relatively short lived in the atmosphere, as it degrades, or is “lost”, over a period of approximately 12 years, “[p]ersistently high emissions of methane will replenish this loss and maintain this initial warming effect”, leading to a continuous wave of additional short term temperature increase,

HIGH METHANE LEVELS . Methane emissions are at dangerously high levels. According to Anderson and Broderick, “Increases in atmospheric methane concentrations have been observed since 2006 as well as regional increases in emissions”, and are at the “top end of IPCC scenarios”. In other words, the levels of methane in the atmosphere are in line with the most pessimistic of the IPCC’s . MET ANE emissions scenarios for future greenhouse gas emission levels (see figure 1).

by relati e to 8 – 9 Although in the long run CO2 emissions remain the main driver of global warming – due to CO2’s much longer lifespan once in the atmosphere – the reduction of methane emissions can have a significant short-term impact on climate change. As Stefan Schwietzke, lead author of a recent peer- 8 reviewed study on the matter published in Nature24 concludes, “reducing methane emissions now will bser ations reduce climate forcing in only a few years – it takes much longer for CO2. And since fossil fuel methane . –3. °C emissions are higher than previously thought, the potential to reduce climate forcing from this specific source is also greater”.25 Moreover, as shown by the Shindell et al peer-reviewed NASA study 26 published in Science, in 2012, a combined effort to reduce CO2 and methane emissions offers the 8 . –3. °C only pathway compatible with limiting warming to well below 2°C (see pink line in Figure 2).
