碳足迹计算器

Estimate your annual carbon footprint from driving, flying, electricity, and diet. The average American produces about 16 tons of CO₂ per year—more than double the global average. Transportation and food are typically the largest contributors. Reducing your carbon footprint doesn't require dramatic lifestyle changes: carpooling, eating less red meat, improving home insulation, and choosing renewable energy options all make meaningful differences. A single transatlantic round-trip flight produces 1.5-3 tons of CO₂, equivalent to months of driving. Switching to an electric vehicle with clean electricity can reduce transportation emissions by 50-80%. Even small changes in diet—like replacing beef with chicken or adding more plant-based meals—can reduce food-related emissions by 25-50%.
