COP26: More than 80 countries commit to 30% methane emissions by 2030

More than 80 countries, including the European Union and the United States, pledged today, Tuesday, during the COP26, to reduce the methane emissions, from greenhouse gases, by 30% by 2030 – compared to 2020 -, announced the President of the European Commission.

“Methane is one of the gases we can reduce as quickly as possible,” and reducing it “could immediately slow down overheating.” Ursula von der Leyen, recalling that this gas is responsible for “almost 30%” of global warming since the time of the industrial revolution.

“Methane is one of the strongest greenhouse gases,” he added. Joe Biden ensuring that the signatories to these commitments represent 70% of world GDP.

The United States and the European Union announced in mid-September that they were working together on this draft agreement, which has since included dozens of other countries, including the Canada, the South Korea, the Vietnam, the Colombia and the Argentina, as broadcast by ΑΠΕ ΜΠΕ.

Methane (CH4) emitted from agriculture and livestock, fossil fuels and waste, is the second greenhouse gas associated with human activity post carbon dioxide (CO2). Although people talk less about it, its effect on overheating is almost 29 times per kilogram of CO2 over a 100-year horizon and almost 82 times over a 20-year period.

Reducing emissions is therefore an “important opportunity” to slow down overheating “in the short term” and “help bridge the gap between existing tracks and those that are compatible with +1.5 degrees Celsius or 2 degrees CelsiusThe United Nations Environment Program (PNUE) highlighted emissions last week.

With “targeted technical measures already available”, these emissions could be reduced by 30% by 2030, of which 20% at low cost, according to the same report. And an extra 15% could come from other measures such as the transition to renewable energy sources and dietary changes.

Overall, such a 45% reduction in methane from human activity during this decade will allow overheating to remain below +2 degrees Celsius, as reported in Paris Agreement, according to another report by the PNUE and the Coalition on Climate and Air Quality (CCAC).

By itself, this measure will allow global warming to be avoided by almost 0,3°C until the decade of 2040, in accordance again with this text.
