On October 19, 2020, EPN commented on EPA’s proposed rulemaking for greenhouse gas (GHG) emission standards that would apply to certain new commercial airplanes, including all large passenger jets. In 2016, EPA found that certain classes of aircraft engines produce GHG emissions that contribute to air pollution and climate change, endangering public health and welfare. These findings triggered a requirement for EPA to promulgate standards addressing GHG emissions from engines on covered aircraft. EPN found that EPA’s proposed rule sets the lowest common denominator for greenhouse gas emissions, and does not meet its statutory responsibility to protect public health. EPN urged EPA to re-propose this rule with standards that reflect meaningful reductions and its own factual findings about the severity of the impacts and the opportunities for greater efficiency.
