Lifehacker brings us two recently launched tools for combating global warming: Zerofootprint’s Carbon Calculator determines your current CO2 emissions based on your lifestyle; and Yahoo! Green assembles your plan for reduction.

On Zerofootprint you can enter figures like what type of car you drive and how much you drive it, your electricity bill and related things like that, and the calculator will figure out how many tons of CO2 you’re adding to the environment. Yahoo! Green is an easy stop to check out discussions on small changes you can make to reduce your emissions count - things we’ve been posting about for some time now too.
