![]() ![]() Aviation is what experts refer to as a hard-to-abate sector, meaning there aren’t currently any easy, market-ready technologies that can drastically reduce its carbon emissions. ![]() ![]() At a meeting in October of the United Nations agency dedicated to civil aviation, delegates from 184 countries adopted net zero by 2050 as a “long-term global aspirational goal.” airlines, have pledged to achieve net-zero carbon emissions by 2050, if not sooner. But major airlines, including six of the largest U.S. And the figures are bouncing back as passengers return to the skies. In the years leading up to the pandemic, aviation emitted roughly a billion metric tons of carbon dioxide annually, about as much as the entire continent of South America in 2021. There’s no guarantee that the industry will get there, but the technologies being developed in pursuit of the target will change aviation, regardless of whether the goal is met. And if global aviation achieves the goal it adopted last year, then your 2050 flight from New York to Hong Kong will result in “net zero” carbon dioxide in the atmosphere. By the middle of this century, most cars and buses should be powered by renewable energy, while bikes, electric trains and your own two feet will continue to have little impact on the climate. ![]()
