FAQ

How much CO2 does a flight emit?

Varies by distance and class. Short-haul economy: ~150-300 kg CO2e. Medium-haul (e.g., coast-to-coast US): ~800-1,200 kg. Long-haul (e.g., NYC to London round-trip): ~1,600 kg (1.6 tons). Business class emits 2-3x more due to more space per passenger. First class emits 3-4x more than economy.

Why does business class emit more CO2 than economy?

Business and first class seats take 2-4x more space than economy, so fewer passengers fit on the plane. When dividing total flight emissions by passenger count, business travelers are responsible for a larger share. Think of it like carpooling: 4 people in a car emit less per person than 2 people in the same car.

Are carbon offsets legitimate?

Depends on the program. Look for Gold Standard or Verified Carbon Standard certifications. Offsets fund projects like reforestation, renewable energy, or methane capture. Cost: $10-30 per ton CO2e. Critics argue offsets allow continuation of high-emission behaviors, while proponents say they fund genuine climate solutions. Best approach: reduce flights when possible AND offset unavoidable travel.
