I actually wrote something up on indirect carbon pricing in the US yesterday. https://news.ycombinator.com/item?id=7829683 https://news.ycombinator.com/item?id=7829683 TL;DR EU carbon is trading at $6.88/tonne. Working back from an enrollment mailer I found that TVA's green power program prices it at $42/tonne (in terms of lbs of CO2 emissions avoided by purchasing blocks of renewable generation).
