mr. gorell, thank you for having me on, emily. overall, i am optimistic, because we have seen a banner year in 2020 sustainability. there is a threat of greenwashing, and it needs to be monitored, it needs to be dealt with. the new chairman of the scaredy and exchange commission just started taking steps here in the u.s., and similarly, we have seen concerns where it needs to be dealt with, but overall, there has been an enormous tripling of sustainability with financing flows since 2016, and flows into esg funds have had a threefold increase since 2015. three-quarters of the economy now is in nations that are under zero commitment. last year, if you look that new electricity generating power plants around the world, 90% of those built last year were solar and wind, and there are lots of similarly encouraging examples, but some of these commitments are for net zero by 2050, which is good, but commitments that will mature when all of the executive teams and all of the political leaders involved
