earlier, i spoke with fred krupp, the president of the environmental defense fund, who is at cop28.ed him what makes this deal so important? >> i have been at this a long time. we have never had as good a day for the climate as we had today. first the methane rules. second we have 50 companies representing 40% of global oil production pledging to eliminate methane pollution and third, we saw an announcement from the u.s. and china, th have agreed to incorporate methane in the future into their pledges internationally. methane is 80 times more powerful than carbon dioxide as a greenhouse gas. reductions now that will happen as a result of the three actions mean storms will be less ferocious, temperatures will be lower, than they would otherwise be over the next 10 years thanks to the actions pledged today. john: is this a long-term solution? >> we have to both do methane to reduce temperatures short-term and we cannot stop working, in fact we have to accelerate work on eliminating carbon dioxide. the oil and gas industry took this one step. they have to do more than this. we have to

i want to bring in fred krupp. we're glad to have you. you said in a statement earlier today that methane reduction could be the most impactful climate action in decades. why is that pledge so important? >> well, methane is 84 times more powerful than carbon dioxide pound for pound. it warms us up a lot and fast. the methane being released this year is going to warm the planet in the next ten years such as all carbon dioxide from all the fossil fuels on the planet. you have to keep working on getting carbon dioxide down, because it lasts for over a hundred years. but if you get the methane down, because it is so powerful in the short term, we can reduce the temperatures we'll experience over the next ten years significantly from what we would otherwise see and reduce the force of cataclysmic storms. >> i want to ask you for people watching, how do you cut the emission of methane, what does that look like practically? >> for compressors that have sealed worn out and not maintained, you replace those. you fix pipes that have sprung leaks. i
