As seen on LifeGoggles, Joel Williams ramps us up on the first R of environmental responsibility: reduce. Of course the whole article is a must-read, so check it out. The jist of the post brings us tools to evaluate how large/small our carbon footprint is, and then gives us snappy ways to implement greener living from the comfort of our own home.
Joel’s words: Whether or not you believe carbon dioxide is the cause of global warming or not, it is harmful to the environment and reducing your carbon footprint is a great idea.
I evaluated myself at one of the several sites mentioned [Carbon Footprint], one that is based out of the UK but has data to compare me to my peers here in central U.S.A. The calculations for the primary emissions are based on a combination of metrics from the UK’s Department for Environment, Food and Rural Affairs (DEFRA), the UK’s Department for Transport, and the US Environmental Protection Agency (EPA). P.s. it was fun. 
I gave US dollar figures for various types of fuel (electricity, coal, natural gas, LP, others) use at home and the results:
Total for your home = 7.437 tonnes of CO2
Total for your cars = 3.124 tonnes of CO2
Total secondary footprint = 4.813 tonnes of CO2
Total = 15.374 tonnes of CO2
* The average footprint for people in United States is 20.4 tonnes.
* The average for the industrial nations is about 11 tonnes.
* The average worldwide carbon footprint is about 4 tonnes.
* To combat climate change the worldwide average needs to reduce to 2 tonnes.
The final stage of the evaluation reveals several options to donate to offset one’s personal carbon footprint!
