Knowledge is power. Find out how you're doing on carbon emissions by completing the survey here.
You don't have to include the "House" section as you may not have that information with you.
Notice how big (and small) some effects are - 1,000 miles for a daily bus commute versus doing that by car, compared to one short plane ride for vacation, for example.
Upload a screenshot of your results, and see how high your "footprint" is compared to the country and where we need to get to. Then you can work on making it lower!
