Aviation and Climate Change
Aviation accounts for about 2.5% of global CO₂ emissions, but its total climate impact is estimated to be 2–4x higher when non-CO₂ effects (contrails, water vapor, NOx) are included. A single transatlantic flight in economy class produces roughly 0.5–1 metric ton of CO₂ equivalent per passenger.
Business vs Economy: The Class Gap
Business class passengers occupy more space and bear a larger share of the aircraft's fuel consumption. A business class seat typically has 3–4x the carbon footprint of economy on the same flight.
Carbon Offsets
High-quality carbon offsets (Gold Standard, VCS) cost roughly $10–30 per metric ton. While offsets don't eliminate emissions, they can fund verified projects like reforestation or clean cookstoves while you work toward reducing flying.
