It focused entirely on Scope 1 and 2 emissions, which are over 1000x times less than our semi-controllable Scope 3 (buildings’ embodied carbon and... Read more

I'm sure we'll learn more soon, but several people have asked on various platforms about how Betsy del Monte is doing (she lives in Asheville, NC, which was hard hit by Hurricane Helene).
