Startup non-profit Zero Footprint has opened Zero Footprint Toronto.
The company is fighting global warming in two ways: encourage carbon reduction, and sell offsets for the remainder.

First, they are encouraging people and companies to be aware of how much carbon they are emitting into the atmosphere through consumption (cars, heating, food, etc.) and encouraging them to find ways to lower those emissions. Via TechCrunch

The goal of the Toronto site is to "The City of Toronto is partnering with Zerofootprint to launch Zerofootprint Toronto, the first ever community-wide initiative aimed at engaging all citizens to fight climate change on a massive scale." The site offers a emissions calculator, list of zero footprint employers, a TechCrunch and other information to help individuals understand their carbon usage and learn what they can do to reduce their footprint. They also work with companies as well:

They've recently signed an agreement with Air Canada that went live just a week ago. The program encourages customers to buy an offset when purchasing a flight ticket on the airline.
