Commercial aviation's key players are backing a target of net zero emissions by 2050, but high costs and opposition from China remain obstacles toward reaching a global climate goal at a United Nations aviation meeting next fall.
to the goal, as aviation faces mounting pressure to reduce emissions from flights.
Airlines want members of the International Civil Aviation Organization to support a global long-term goal that would influence governments to take action to achieve the target, like funding the production of sustainable aviation fuel. "If ICAO is able to identify and agree on a clear long-term aspirational goal, that will make an enormous difference in pointing the direction ... toward meeting that goal," Petsonk told a recent forum.Aviation was excluded from the landmark 2015 Paris climate accord, where countries agreed to limit the rise in global temperatures to 2 degrees Celsius above pre-industrial levels and preferably to 1.5 degrees.
ICAO's governing council is weighing the impact of a long-term goal on growth and on costs to aviation, especially for developing countries. "I think we're going to see the same debate play out at ICAO during the next assembly," said Dan Rutherford, aviation director at the International Council on Clean Transportation, an environmental research group based in Washington.
