Want to know how much your consumption habits are contributing to global warming? Climate Counts, a new nonprofit organization, now lets you see how companies rank in the fight against climate change before you go shopping.

On its recently launched website, Climate Counts scores 56 companies from 0 to 100 based on how they measure their greenhouse gas emissions, their plans to reduce them, their stance on legislation, and how fully they disclose these activities. The methodology focuses heavily on public disclosure of activities and policies, so the emphasis is on which companies talk the climate change talk, but not necessarily on which ones follow words with actions.

Canon comes out on top with a score of 77, while Amazon.com, Wendy's, Burger King and CBS find themselves at the very bottom of the climate-friendly ladder. The New York Times reports that Climate Counts gave Amazon.com a zero because researchers could not find relevant data about its role in climate change. Amazon's response? Climate Counts just didn't look very hard. 

I'm not sure what kind of impact the group thinks it can have on consumption patterns, but I highly doubt it'll be convincing die-hard Pepsi fans (score: 26) to switch to Coke (score: 57) anytime soon. At best, these endeavors are good for the embarrassment factor they create. Maybe now, companies at the bottom will feel a need to step up their efforts—or at least make their policies easier to find.
