Methane (甲烷) is a greenhouse gas. Over 20 years it has over 80 times the planet-cooking power of carbon dioxide, and is 1 for nearly 45%of warming today. Because methane is the main 2 of natural gas, much of man-made emissions comes from the energy industry. Yet because it is short-lived, controlling methane offers the world its best possible chance for 3 progress against climate change.
As COP28, the UN's climate summit, gets 4 in Dubai, it is greatly encouraging, therefore, that the chances of such a deal on methane are good. Negotiators must 5 at a rare opportunity to strike one.
The reason a deal looks possible is that the politics are promising in all the biggest markets. China has recently announced that it will start including methane in its national climate plans. America will soon finalize regulations to 6 methane emissions from its huge oil and gas sector, including measures that cover leaky pipelines and storage. And the European Union has also agreed on tough methane standards, covering both domestic sources and 7 fossil fuels.
8 are helping, too. A range of new technologies for monitoring methane will help 9 large sources of emissions from the energy industry. Because oil and gas firms can often sell methane (rather than wastefully burning or releasing it), many investment s to avoid 10 will pay for themselves. Most firms do not invest because of the trouble, higher returns on other projects, or wells' distance from consumers. Whatever the reason, they suffer no 11 for adding needlessly to global warming.
Since green-washing, the process of conveying a false impression about how some products or measures are environmentally sound, is quite common, if a global methane deal is to be more than that, 12 , it will need rigour(缜密). Methane-control seemed to 13 at the UN climate summit in Glasgow two years ago, when negotiators 14 came up with a proposal to cut emissions by 30% by 2030.Yet the deal was voluntary, and had no enforcement mechanisms (机制); emissions have since 15 . An agreement this time round must link promises to national climate plans and, crucially, to domestic enforcement mechanisms.
