Two-thirds of the more than 350 comments submitted to the U.S. Environmental Protection Agency (EPA) about its proposed rule to control and set standards for turbine airplane emissions said it falls far short and should be more stringent.
The proposal is intended to bring emissions standards and test procedures in line with those of the International Civil Aviation Organization (ICAO), but critics noted the rule goes no further to actually “reduce” greenhouse gas (GHG) emissions. As one organization put it: “This proposed rule is meant solely to comply with the minimum standards set by ICAO with no foreseeable reduction in emissions that can be attributed to the proposed rule.”
Other commenters criticized the proposal for not recognizing the successes made in the use of sustainable aviation fuel (SAF). “By setting more challenging, yet achievable, mandates, EPA can create an environment for investment that can support additional production and use of SAF to help the aviation sector reduce emissions,” wrote a major oil company.
Several organizations and associations, including NBAA, were critical of the proposal’s reporting requirement. NBAA also mentioned in its comments an international program to significantly reduce business aviation’s harmful emissions over the next 30 years.
