Details of a new commitment between the United States and the European Union to reduce emissions of methane - a potent greenhouse gas - will be announced on Friday, a source told CNN close to deal. US and EU should commit to reducing methane emissions from almost a third by 2030, based on 2020 levels, according to a Washington Post report which cited an EU official. The announcement would come the same day that President Joe Biden and other world leaders hold a virtual closed-door climate meeting, ahead of a United Nations Climate Conference in Glasgow in November. Reuters initially reported that the US and EU were pursuing a methane reduction deal. A spokesperson for the US State Department and a White House spokesperson declined to comment. The EU official quoted in the post said the US and EU governments are trying to get other countries to sign the engagement before Glasgow. Scientists say this gas invisible could seal our fate on climate change Read moreWith the the Earth is warming rapidly , scientists talk about methane emissions must be reduced quickly. Charles Koven, one of the main authors of the 's report UN on climate change released in August, told CNN it was due to the incredible warming powermethane. Even though carbon dioxide stays in the atmosphere longer, methane is a much more potent greenhouse gas, trapping 25 times more heat. The short lifespan of methane is why countries are targeting it to rapidly reduce greenhouse gas emissions and their impact. The fastest way to mitigate some of the climate change we are already seeing in the short term is to reduce methane, Koven told CNN. If we were to reduce methane emissions, it would act to offset one of those sources of warming. If the world stopped emitting carbon dioxide tomorrow, Koven said, global temperatures would not start. not to cool for many years due to the length of time the gas remains in the atmosphere. Methane reduction is the easiest knob to turn to change the global temperature trajectory at the cofor the next 10 years, he said.
