Calculate your carbon footprint from transportation, energy, diet, and lifestyle choices
A carbon footprint calculator estimates your annual CO2 emissions from transportation, home energy use, diet, shopping, and lifestyle choices, expressed in tons of CO2 equivalent per year. Average American produces 16 tons CO2 annually, while global average is 4 tons—climate scientists recommend 2 tons per person to limit warming to 2°C. Calculates emissions from driving (vehicle type, miles driven), flying (flight frequency and distance), home energy (electricity, gas, heating), diet (meat consumption), and consumption patterns. Essential for environmental awareness, carbon offsetting, and reducing personal climate impact.
Understand your climate impact with specific numbers rather than vague guilt—knowing you produce 12 tons CO2 annually gives concrete reduction targets. Identify biggest emission sources: for many Americans, driving and flying account for 60% of footprint, making vehicle and travel choices highest-impact areas for reduction. Make informed decisions about effective climate actions—switching to electric vehicle saves 4-5 tons CO2 yearly while bringing reusable bags to grocery saves 0.01 tons. Calculate cost-benefit of eco-investments: solar panels reduce emissions AND save money long-term. Support carbon offset programs by knowing exact tons to offset ($10-30 per ton typically). Companies use this to calculate employee or corporate carbon footprints for sustainability reporting and ESG goals.
Enter annual miles driven (and vehicle MPG or type), flights taken (short-haul, long-haul, frequency), home size and heating/cooling fuel type, electricity usage (kWh monthly from utility bill), diet type (meat-heavy, moderate, vegetarian, vegan—diet accounts for 2-3 tons CO2 annually), and consumption habits. Results show total CO2 tons per year, breakdown by category, comparison to national and global averages, and specific reduction recommendations. Reduce footprint by: driving less or switching to EV (save 2-5 tons), reducing flights (each transatlantic roundtrip = 2 tons), home energy efficiency upgrades (save 1-3 tons), plant-based diet (save 1-2 tons), conscious consumption (repair vs replace, buy local).
