UN agency proposes limits on airlines carbon emissions
After more than six years of negotiations, the global aviation industry agreed on Monday to the first binding limits on carbon dioxide emissions, tackling the fastest-growing source of greenhouse gas pollution.
The deal is the latest in a series of international efforts to address climate change. Until now, airplanes had not been included in any international climate change deals, like the recent Paris Agreement, or the Montreal Protocol, expected to be completed later this year.
The proposed new rules, announced in Montreal by the International Civil Aviation Organization, the United Nations’ aviation agency, would apply for all new airplanes delivered after 2028.
Airlines account for about 2 percent of global emissions — about the same as Germany. But many analysts think the emissions could triple by the middle of the century given the expected growth in air travel over the next decades.
It took little time, though, for the announcement to set off a debate over how effective the proposed rules would be.
Some environmental groups, pointing to the airline industry’s close involvement in crafting the deal, said the proposed rules were too weak and failed to include aircraft currently in use.
But advocates of the deal, including the Obama administration, praised it, saying that it was an important first step and that it tackled one of the most intractable rifts over reducing carbon emissions.
“This is another example of the administration’s deep commitment to working with the international community on policies that will reduce harmful carbon pollution worldwide,” Michael Huerta, head of the Federal Aviation Administration, said in a statement.
In a statement, the White House said that “without additional action, emissions from the aviation sector are projected to grow by nearly 50 percent.”
The proposed rules signaled the first time that the aviation sector had been given emissions standards, just as cars and commercial trucks now have.
The new standards would require a 4 percent reduction in fuel consumption of new aircraft starting in 2028 compared with 2015 deliveries. They also set new limits for airplanes in production that are delivered after 2023. Depending on the size of the aircraft, actual reductions would be from zero to 11 percent, with a bigger emphasis on larger commercial airplanes, according to analysts with the International Council on Clean Transportation.
Before they become binding, the new standards must be formally adopted by the civil aviation council of 36 member states, in June this year, and then endorsed by the council’s assembly in October. They would then need to be enacted by each member state in its national legislation or regulation, although countries have the option to adopt even stricter restrictions on emissions.
The Obama administration last year issued a legal finding that aviation emissions are a threat to human health because of their contribution to global warming. That finding initiated a requirement under the Clean Air Act that the government release new regulations to curb airplane emissions.
Because of the global nature of the industry, however, the administration said at the time it would wait for the new rules before drafting its own standard.
“The Obama administration last year issued a legal finding that aviation emissions are a threat to human health because of their contribution to global warming.”
a legal finding..please..
“The proposed new rules, announced in Montreal by the International Civil Aviation Organization, the United Nations’ aviation agency, would apply for all new airplanes delivered after 2028.”
wow..such a delay..
“Before they become binding, the new standards must be formally adopted by the civil aviation council of 36 member states, in June this year, and then endorsed by the council’s assembly in October.”
watch the lemmings line up..
