EPA's Greenhouse Gas Equivalencies Calculator

This is a handy calculator for generating the GHG data for various energy inputs, say 100 gallons of gasoline, 50 passenger cars, or 250 KW of electricity.
For instance the results of 100 gallons of gas burned is the equivalent of:
- CO2 emissions from 2.1 barrels of oil consumed,
- Carbon sequestered annually by 0.19 acres of pine or fir forests,
- CO2 emissions from burning 0.005 railcars’ worth of coal,
- Greenhouse gas emissions avoided by recycling 0.31 tons of waste instead of sending it to the landfill.
And the list goes on...you get the idea.
