The Environmental Protection Agency is implementing rules about greenhouse gas emissions for commercial planes. This is the first time a government agency has put such rules in place and it is a nice gesture but the EPA says that they will not actually lower any emissions as a result.
What the rules do accomplish is require aircraft manufacturers to use fuel-efficient engines that release less heat-trapping carbon dioxide by 2028. The EPA says that many aircraft already meet these requirements.
Commercial aircraft make up 3% of the country’s greenhouse gas emissions. Instating these rules helps the government avoid a lawsuit that would have forced them to regulate these emissions but since they don’t really require major changes, it’s more of a governmental gobbledygook that does not help Mother Earth at all.
