US greenhouse gas emissions fell 10% in 2020 as Covid curbed travel

But emissions reductions came at huge cost and will likely rebound as vaccines are distributed, authors of report say

Planet-heating emissions in the US fell by more than 10% in 2020, a record drop generated by extraordinary reductions in travel and industrial activity in the teeth of the coronavirus pandemic, new figures show.

The historic jolt to American life, which has resulted in more than 375,000 deaths and a huge surge in joblessness, caused many states to impose travel restrictions and curbs on business activity. This resulted in greenhouse gas emissions dropping by 10.3% last year, according to a new estimate by Rhodium Group.
