Frequently Asked Questions

What's a typical carbon footprint?
Global average: 4.7 tonnes CO2/year. USA: ~16 tonnes. EU: ~8 tonnes. Climate target: 2 tonnes/year by 2050 to hit 1.5°C goal. Most individuals far exceed sustainable limits.
Biggest footprint contributors?
For most: (1) flights — one transatlantic flight = 1-2 tonnes. (2) car driving — 10K km = 1.5-2 tonnes gas. (3) home heating especially with gas/oil. (4) meat-heavy diet. Electricity less if grid is clean.
Is offsetting meaningful?
Offsets vary wildly in quality. Tree planting is slow + reversible. Direct air capture (Climeworks) is real but expensive ($500-1000/tonne). Better: reduce first, offset the rest. Gold Standard / Verra certifications are least bad.
Biggest levers to reduce footprint?
(1) Skip long-haul flights — largest per-hour impact. (2) Eat less meat (especially beef). (3) Electric car if you drive a lot. (4) Heat pump instead of gas. (5) Insulation. Don't waste effort on small stuff (plastic straws) vs big stuff (flights).
Is this exact?
Non — all footprint calculators are estimates with ±30% variance. Useful for relative comparison + identifying big levers, not precise accounting.
