How many trees would it take to offset your annual emissions?
1 mature tree absorbs ~22 kg CO₂/year. Alternative: invest in verified carbon offset programs (~$15-30/ton).
Methodology: Based on EPA WARM model, WWF Footprint Calculator, and IPCC emission factors. Grid intensity varies by country (US avg 0.42 kg CO₂/kWh, UK 0.21, France 0.06, China 0.58). Flight emissions: ~255 kg CO₂/hour (short-haul avg). Diet emissions: meat-heavy ~3.3 tCO₂e/yr, vegan ~1.5 tCO₂e/yr. This is an estimate — actual footprint depends on specific behaviors, product choices, and local infrastructure. For precise auditing, consider professional carbon accounting services.
