While the main greenhouse gas emission from powered aircraft is CO 2, jet airliners contribute to climate change in four ways as they fly in the tropopause: [6] Carbon dioxide (CO 2) CO 2 emissions are the most significant and best understood contribution to climate change. [7] The effects of CO 2 emissions are similar regardless of altitude.
He and his colleagues concluded that if the federal government paid the six largest U.S. carriers to scrap 65 older model planes between 2015 and 2019 rather than sell them, it would have cost ...
Biden announced a goal in 2021 to reduce aviation emissions 20% by 2030 and replace all kerosene-based jet fuel with sustainable fuel by 2050. Planes contributed about 9% of planet-warming emissions from the transportation sector in the U.S. in 2022, according to the U.S. Environmental Protection Agency.
Jatropha, used for biodiesel, can thrive on marginal land where most plants produce low yields. [10] [11] A life cycle assessment on jatropha estimated that biofuels could reduce greenhouse gas emissions by up to 85% if former agro-pastoral land is used, or increase emissions by up to 60% if natural woodland is converted. [12]
The California Air Resources Board reports that state carbon emissions dropped about 9.3 million metric tons in 2022 compared to 2021. The California Air Resources Board reports that state carbon ...

To reach either 2030 target, California carbon emissions would need to fall each year by 13.6 and 17.2 million tons of carbon dioxide equivalent per year, respectively.
