Low-Carbon Fuels

The transportation sector accounts for 28% of U.S. greenhouse gas emissions. Emissions increased more in absolute terms than any other sector from 1990 to 2018, due to population growth and a surge in economic activity. Therefore, countries around the world, including the U.S., are racing toward low-carbon alternative fuels.

Although the distant future may see a world powered entirely by carbon-free renewable energy sources such as wind and solar, technological and infrastructural constraints currently make for a world still reliant on fossil fuels. Consequently, before fossil fuels are entirely phased out, the opportunity to make these fuels less carbon-intensive exists.
