America did not have such a provision set in stone until last week, but that doesn’t mean aircraft manufacturers weren’t complying. The Environmental Protection Agency (EPA) decided to make things official though and announced it finalized its emission standards for commercial airplanes and jets.
Sure, this will help save the planet, but that’s just a side effect of a move meant to ensure “domestically manufactured aircraft remain competitive in the global marketplace.“ And that’s because three-quarters of all airplanes made in the U.S. are sold overseas, including from Boeing, which immediately jumped to praise the decision.
“We are proud that the EPA took this step to finalize the ICAO CO2 standard for aircraft emissions. This is vital for protecting the environment and supporting the sustainable growth of commercial aviation and the United States economy. The EPA’s standard will help tackle climate change and ensure that Boeing products will meet the same requirements as our competitors around the world," said the American aerospace company in a statement.
“Aviation is one of only two industrial sectors that has adopted global CO2 goals, underscoring our steadfast commitment to our communities and the planet.”
You can read the provisions of the EPA document in the attached PDF - it essentially calls for aircraft emission levels to drop to half the 2005 value by 2050.
