NBAA appealed to the Environmental Protection Agency to "respect global efforts" as it proceeds with a rulemaking that would establish an aircraft emission standard. In tandem with a proposed finding that greenhouse gas (GHG) emissions from certain aircraft engines endanger public health and welfare, the EPA in June released an advanced notice of proposed rulemaking discussing the possibility of regulating aircraft- carbon emissions.

In comments, NBAA stressed that the U.S. efforts “not be viewed as unilateral or ignorant of international visibility.”  Coordinated implementation of emissions standards would help ensure compliance and reduce confusion, the association said. NBAA urged the EPA to wait for the international Committee on Aviation Protection to finalize a global emission standard in February before taking action.

While acknowledging a push by environmental concerns to exceed international recommendations, NBAA said, “Any recommendations for changes in aviation emissions or stringencies must flow from internationally developed and supported standards. Arbitrarily setting a higher standard will have significant negative consequences that could result in a patchwork of uncoordinated standards, stifle innovation, increase costs and harm U.S. exports.” NBAA also reiterated that business aviation is responsible for just 0.04 percent of man-made carbon emissions and has established goals for carbon-neutral growth, fuel efficiency improvements and CO₂ reductions.
