The Obama Administration has initiated talks on restricting the aerospace industry’s greenhouse gas emissions, stating that it might take some time before exact regulations take effect.
According to the EPA, like the automobile industry and power plants, airplanes also negatively impact human health; thus, restrictions are necessary. Creating the regulations will take some time — nothing will be enacted while Obama is in office, and will be the next president’s responsibility.
The EPA is waiting for the International Civil Aviation Organization (ICAO), which is tasked with creating international aviation regulations, to develop worldwide carbon emission rules. The deadline is February 2016; ICAO members are obligated to enact international regulations approved by the agency. The EPA is collaborating with multiple international agencies, like the ICAO, to create aerospace regulations.
Environmentalists would like the EPA to issue their rules before February 2016 because they worry that the ICAO — an agency that works with both the EPA and airline industry — will be biased and present lenient restrictions. Environmental groups want the US to lead the way.
Per the Flying Clean campaign, flights in and out of the US constitute almost one-third of the world’s airplane emissions; airline emissions will likely double by the end of 2020 if nothing is done soon.
Of course, Republicans have their issues with Obama cutting airplane emissions, specifying that airfare prices will skyrocket and hurt domestic air travel. Airline companies agree, explaining that they have already done so much to curb emissions, including using fuel alternatives, enhancing aerodynamics, and using lighter inflight materials. As reported by the International Air Transport Association, decreasing an airplane’s weight by 5.5 pounds is equivalent to a one-ton cut in yearly carbon emissions.
But the aviation industry continues to grow: more and more people are flying each year. Although air flights only comprise 2 percent of worldwide emissions, it’s projected that by 2020, international flights can reach 70 percent above 2005 numbers, regardless of whether fuel efficiency is advanced by an annual 2 percent.
To combat this, in the past, the EU tried to enact the Emissions Trading System, which was subsequently banned by the US, China, and other countries. With the support of both Democrats and Republicans, Obama even passed the European Union Emissions Trading Scheme Prohibition Act of 2011, which banned American airlines from partaking in the EU’s system.
Airlines have pledged to limit their emissions by 2 percent every year until 2020, when emission growth will cap. The ultimate goal is for the aerospace industry’s emissions to be at half 2005′s numbers by 2050.
At this point, using newly-made airplanes that have better fuel economies are our best bet. Boeing has introduced its new 787 Dreamliner and Airbus has introduced the A350, both of which are more fuel efficient but not in wide use just yet.
