Significance President Barack Obama has directed several departments and agencies, most notably the EPA, to issue directives and regulations that would impose progressively lower ceilings on GHG emissions. However, the Republican-controlled Congress has repeatedly targeted these regulations for repeal. Impacts The US market will probably have an standard-setting effect on the air industry, as it accounts for one-third of global emissions. Higher standards, if enacted on a per passenger basis, will favour larger planes. This will, in turn, support a hub-and-spoke model, leading to growth at major airports worldwide.
