With air travel over the holiday season bouncing back – despite the Omicron variant – what are the best prospects for taking the emissions out of aviation? In the US, in mid-December, more than two million people per day were passing through the TSA’s checkpoints. That is still significantly below pre-pandemic levels, but it is roughly double the numbers in the same period of 2020.
Even with the pandemic still raging, people want to fly. That is a real problem for getting to net zero. Aviation emissions are small, accounting for a little under 2% of total global greenhouse gas emissions, but their share is rising. Sustainable aviation fuel and electric planes, are they a viable solution yet?
