Airlines and CO2

Aviation accounts for about 2.5% of global carbon emissions. This is a big deal because it would make the aviation sector the world’s 7th largest carbon emitter if it were a country. Airlinesaccount for roughly about 1 billion tons of carbon emissions. Sweden, Greta Thunberg’s home country, contributes 40 million tons. California, the leader in US climate policy, accounts for about 250 million tons. Thus, aviation accounts for 25 times Sweden’s emissions and four times California’s emissions.
