The UN aviation agency ICAO uses offsetting as its key mechanism to decarbonise aviation, adding just €2.40 to the price of a long-haul flight (1), new data by Transport & Environment (T&E) finds. / ICAO, the UN body tasked with cutting global aircraft emissions, uses a system of purchasing emissions offsets that has so far proven totally ineffective for reducing aviation’s climate impact. New analysis by T&E shows that on a flight from Europe to the United States, on average passengers would have to pay as little as €2.40 to offset their carbon emissions in 2030[2]. On a flight to the Middle East, the added cost per passenger would be €1.40; to China, a mere €3.5. Such amounts are inadequate when considering the cost of decarbonising the aviation industry, T&E says. (....)
