Yep, that's a big conference alright!
LOL! And they don't even say how many were "environmental experts" [sic] (never mind what their supposed qualifications are!) and how many were carbon market scammer-- oops! "participants."
It's a real whopper. I have enough room for all the them to assemble on my driveway. I'll bet a careful check of credentials could vastly lower the number who really deserve the title "expert".
