Total Annual CO2 vs Annual Miles Driven
公式
## How Carbon Footprint Is Estimated Your carbon footprint includes emissions from transportation, home energy, and air travel. ### Emission Factors Used - **Driving**: 19.6 lbs CO2 per gallon of gasoline - **Electricity**: 0.92 lbs CO2 per kWh (US average) - **Natural Gas**: 11.7 lbs CO2 per therm - **Flights**: ~90 kg CO2 per flight hour per passenger (x 2.2 for lbs)
计算示例
12,000 miles at 28 MPG, 900 kWh/mo electricity, 40 therms/mo gas, 10 flight hours.
- 01Driving = 12,000 / 28 x 19.6 = 8,400 lbs CO2
- 02Electricity = 900 x 12 x 0.92 = 9,936 lbs CO2
- 03Natural gas = 40 x 12 x 11.7 = 5,616 lbs CO2
- 04Flights = 10 x 90 x 2.2 = 1,980 lbs CO2
- 05Total = 8,400 + 9,936 + 5,616 + 1,980 = 25,932 lbs = 11.8 tonnes
常见问题
What is the average carbon footprint in the US?
The average American produces about 16 metric tonnes of CO2 per year, one of the highest per-capita rates in the world. The global average is about 4 tonnes.
How can I reduce my carbon footprint?
Drive less or switch to an EV, improve home insulation, use renewable energy, fly less, eat less meat, and reduce waste.
What is a carbon offset?
Carbon offsets fund projects that reduce emissions elsewhere (tree planting, renewable energy, methane capture) to compensate for your own emissions.
