Knowledge is power. Find out how you're doing on carbon emissions by completing the survey here.
If you live in a dorm, answer as "Apartment building of more than 5 units", and "less than 500 sq ft", otherwise answer for your actual residence during semester.
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!
P.S. If we find a screenshot that's been uploaded more than once (we have our ways) no points will be allowed. Sorry, but it's really easy to do it properly and cutting corners doesn't help SaveOhno.
