Carbon Footprint & Tree Offset

Estimate your annual carbon footprint, see how many trees it equals, and find out what it would cost to go carbon neutral.

🚗 Transportation

Miles driven per yearThe average American drives about 13,500 miles/yr. Check your odometer or use your insurance estimate.

Vehicle typeGas sedan: ~0.79 lbs CO₂/mile (28 mpg). SUV/truck: ~1.05 lbs/mile (21 mpg). Hybrid: ~0.45 lbs/mile. EV: emissions depend on your electric grid; see Home Energy.

Flights (updated estimates)Round trip with radiative forcing factored in: short ~900 lbs, medium ~2,500 lbs, long-haul ~5,500 lbs CO₂. A NYC–London round trip alone is ~4,000–5,500 lbs.

🏠 Home Energy

Electric grid mixA WV user and a CA user with identical bills do NOT have the same footprint. Coal-heavy: ~1.7 lbs CO₂/kWh (WV, KY, WY). US average: ~0.85 lbs/kWh. Cleaner grid: ~0.4 lbs/kWh (CA, NY, OR). Renewable / solar at home: ~0.1 lbs/kWh.

Monthly electric billUsed to estimate kWh consumption at ~$0.17/kWh, then multiplied by your grid's emission factor. Your home size is already captured here -- bigger homes have bigger bills.

Monthly gas billNatural gas produces 11.7 lbs CO₂ per therm. At ~$1.50/therm, $80/mo ≈ 53 therms ≈ 625 lbs CO₂/mo.

Household occupantsHome emissions split equally among occupants. A family of 4 sharing one home has a lower per-person footprint than one person in the same house.

💰 Household income (for comparison)

Not added to your footprintYour income bracket is used only to compare your footprint to others at your income level -- not to inflate your number. Research shows carbon footprint scales strongly with income.

Average footprints by bracket (US)Under $50k: ~12.5 tons/person. $50k–$100k: ~16 tons. $100k–$200k: ~22 tons. $200k+: ~32 tons. Source: Ivanova & Wood (2020), EPA consumption data.

This calculator is for educational and informational purposes only. Results are estimates based on EPA emission factors, IPCC guidelines, USDA Forest Service sequestration rates, and Poore & Nemecek (2018) food system data. Your actual footprint depends on your specific utility grid, diet composition, and local supply chains. Always consult qualified experts for decisions involving carbon accounting, climate strategy, or offset purchases.
