US domestic aviation emissions could increase 33-50% by 2030 as a result of Trump climate withdrawal

Although there has been recent speculation over the possibility of the United States not joining the voluntary phase of ICAO’s CORSIA carbon offsetting scheme as a result of President Trump’s decision to withdraw from the Paris climate agreement, there are other implications for global aviation emissions. Pledges made by countries under the agreement must take into account reductions in domestic aviation emissions, which are not covered by CORSIA. Globally, domestic aviation emissions make up around 38% of all aviation emissions, with the US responsible for nearly a half. According to research by Manchester Metropolitan University’s Centre for Aviation, Transport and the Environment (CATE), US domestic aviation emissions could rise by 33-50% over 2005 levels if the US does not carry out its CO2 reduction plans and so heavily impact the sector’s overall emissions.

“Aviation falls into two categories in terms of its CO2 emissions – domestic aviation, which is accounted for by the country that emits it, and international aviation, which falls to ICAO, thus Trump’s actions affect any potential reduction of US domestic aviation CO2 emissions,” explained CATE’s Professor David Lee.[...]
