One of the top agenda items at the 27 th annual UN Conference of the Parties (COP27) climate meeting in Sharm El-Sheikh, Egypt—now in its second week—is how to implement the Global Methane Pledge launched at last year’s COP26 negotiations in Glasgow, Scotland. But its short lifetime in the atmosphere is also a reason for hope.
