it of more on this i'm doing by peter erickson, director of the stock home environment institute climate policy program. he joins us live from seattle in the united states. thank you very much for taking the time to speak to us. your reaction to this landmark. really this is not surprising and far reaching. burt, it requires shell to reduce that submission by 45 percent by 2030. that's just the decade from now. and the biggest thing about that, it covers the emissions from the products that shell make, so petrol or oil or diesel vehicle that that shell ultimately extract it from, from the ground is covered by rolling. i'm not aware of any other requirement for the company to reduce emissions from all the way from what when, when and extracts the oil to when it's burned. so this is a big deal. how do you see shell committing to this in practical terms? i think what i'm 45 percent is a big reduction compared to where they are and they have hundreds of millions of tons of missions annually, including those missions from burning their products. and so i think what they're going to have to do
