co2
Like most people in this country, Satan is my motor. So, I spent an evening figuring out exactly how much CO2 emission Julie and I have unique responsibility for. I added up our natural gas, electricity and gasoline used by our house and car. Planting another tree in the back yard won’t solve the problem. It takes roughly 7 acres of forest to match the rate with which our household is emitting CO2.
The Harvard Green Campus Initiative provides a Emissions Factors table, but I can not find any original sources cited.
