U.S. unveils roadmap for net-zero aviation emissions by 2050
The Transportation Department is unveiling a multi-agency roadmap to slash greenhouse gas emissions from the U.S. aviation sector with a target of reaching net-zero by 2050.
Why it matters: Aviation accounts for around 3% of global carbon emissions, but has other warming impacts too. It accounts for 11% of U.S. transportation-related emissions, according to the White House.
Those emissions are projected to rise a lot in coming decades alongside the growth of air travel, absent aggressive adoption of climate-friendly tech.
In a hypothetical case of technology frozen in place, the strategy estimates that U.S. aviation emissions in 2050 would be around twice their 2019 levels.
