In this episode, Kyla and Kristen are joined by climate activist Robert Miller to talk about carbon offsets. Robbie laughs when he learns that the Vatican tried to buy what he describes as climate indulgences. Kyla is shocked that Canadian forests have been net emitters since 2001. (Stupid pine beetles!) Topics: what are carbon offsets; principles of good carbon offsets programs; problems with carbon offsetting; certification schemes; should you use carbon offsets and, if so, how should you buy them.
