lisa friedman from climate wire. i always was interested in vietnam and the number you stated about the 30% per capita emissions increase. it sounds like perhaps you're saying that the concern about emissions rise in developing countries is a little misplaced. can you talk about, you know, with an energy strategy stuck at the world bank for more than a year now, you know, what -- what is the bank's plan now for balancing the need to develop sustainably and not cause irreversible damage with the pressure from developing countries to build with coal? >> great. thank you very much. why don't we go to tim and then to vijay. >> it's a really good question on renewables. it's the rate of renewable entry into -- not the absolute percentage, whatever it is today. by 2030 we're going to double that? no. the rate of penetration annually we hope is going to double. and that's happening in many, many places across the world. even in our own backyard, we've seen renewable goals that get set that are not only being achieved, but n
