Carbon offsetting is the practice of compensating for CO2 emissions by investing in projects that remove or reduce greenhouse gases elsewhere, such as reforestation or renewable energy projects.
We calculate emissions based on your distance traveled, fuel efficiency, and fuel type. Gasoline produces about 8.89 kg of CO2 per gallon burned, which we divide by passengers to get per-person emissions.
Transportation accounts for about 29% of U.S. greenhouse gas emissions. Offsetting helps neutralize your environmental impact and supports climate-positive projects while you work toward reducing emissions.
Offset funds typically support verified projects like forest conservation, renewable energy development, methane capture, or direct air capture technologies that remove CO2 from the atmosphere.
Look for offsets certified by recognized standards like Verra VCS, Gold Standard, or Climate Action Reserve. These ensure projects are real, additional, permanent, and verified by third parties.
Avoiding emissions (driving less, using public transport) directly reduces your footprint. Offsetting compensates for unavoidable emissions by supporting projects that remove equivalent CO2 elsewhere.
Our calculations provide estimates based on standard emission factors. Actual emissions may vary due to driving conditions, vehicle maintenance, weather, and other factors not captured in this simplified model.
Carbon offset prices vary widely, from $5-$100+ per tonne of CO2, depending on project type, certification standards, and market conditions. Higher-quality, certified offsets generally cost more.
