For the first time, the EPA has proposed a rule setting an emission standard for nearly all commercial aircraft for greenhouse gas emissions. The EPA's proposed standard closely follows the standard adopted by the International Civil Aviation Organization in 2017, which was the world's first global design certification standard governing CO2 emissions for aircraft. The EPA standard would apply to all covered aircraft for which a new design type certificate is requested on or after January 1, 2020, and would apply to in-production aircraft beginning January 1, 2028. The proposed rule is expected to have little impact on manufacturers as the industry is already largely compliant with the standard.
