![]() “The good news is that most of the required actions bring not only climate benefits but also health and financial benefits, and all the technology needed is already available. “To achieve global climate goals, we must reduce methane emissions while also urgently reducing carbon dioxide emissions,” Dr Shindell said. “Additional measures that do not specifically target methane, like a shift to renewable energy, residential and commercial energy efficiency, and a reduction in food loss and waste, can reduce methane emissions by a further 15 per cent by 2030.”ĭrew Shindell, a Professor of Climate Science at Duke University in the USA, who chaired the assessment for the CCAC, said urgent steps must be taken to reduce methane emissions this decade. “But targeted measures alone are not enough”, the partners warned. For example, whereas the largest potential in Europe and India is in the waste sector, in China it is from coal production and livestock, while in Africa it is from livestock followed by oil and gas. So-called “mitigation potential” varies between countries and regions, according to the report. Most, or around 60 per cent, are low cost and half have “negative costs”, meaning companies will make money from taking action. ![]() The Assessment identifies readily available solutions that would reduce methane emissions by 30 per cent by 2030, mainly in the fossil fuel sector. “The United States is committed to driving down methane emissions both at home and globally-through measures like research and development, standards to control fossil and landfill methane, and incentives to address agricultural methane”, he said. Methane accounts for nearly one-fifth of global greenhouse gas emissions, according to Rick Duke, Senior Advisor to John Kerry, the US Special Presidential Envoy on Climate Change. However, unlike CO2, which stays in the atmosphere for centuries, methane breaks down quickly and most is gone after a decade, meaning action can rapidly reduce the rate of global warming in the near-term. The report underscores why international action is urgently needed as human-caused methane emissions are increasing faster than at any time since record keeping began in the 1980s.Įven with the COVID-19 pandemic causing an economic slowdown in 2020, which prevented another record year for carbon dioxide (CO2) emissions, data from the United States National Oceanic and Atmospheric Administration (NOAA) shows the amount of methane in the atmosphere reached record levels last year. Most human-caused methane emissions come from three sectors: fossil fuels, such as oil and gas processing landfills and waste and agriculture, chiefly related to livestock. Methane is an extremely powerful greenhouse gas, responsible for around 30 per cent of warming since the pre-industrial era. A row is raging over Africa’s largest dam science has a solution. The benefits to society, economies, and the environmental are numerous and far outweigh the cost”, said Inger Andersen, the UNEP Executive Director. The extent and drivers of global wetland loss. ![]() “Cutting methane is the strongest lever we have to slow climate change over the next 25 years and complements necessary efforts to reduce carbon dioxide. The triggering of methane release induced by anthropogenic transfer of carbon to the atmosphere is leading to a major shift in state of the terrestrial atmosphere and habitats.The study is the work of the Climate and Clean Air Coalition (CCAC), a global partnership of governments and non-State partners, and the UN Environment Programme (UNEP). Compounding this effect is extensive drilling for coal seam gas, perforating the crust in several parts of the world and releasing commercial and fugitive emissions of methane into the atmosphere. Global warming is a major factor leading to the disappearance of species throughout the planet at a rate two orders of magnitude faster than they would have without human interference. This release threatens to melt large parts of the polar ice caps, leading to meters to tens of meters of sea level rise. Global warming, driving a mean rise of 3 to 8 ☌ in the Arctic early during 2015- 2018, is leading toward the release of billions of tons of methane into the atmosphere, from permafrost, lakes, shallow seas and sediments. During much of the upper Cenozoic, the accumulation of organic matter in Polar Regions, as well as in bogs in tropical and subtropical zones, has created large reservoirs of methane, the most potent common greenhouse gas, vulnerable to release upon a rise in temperature.
