The Treasury Department has released guidance on the tax credit for sustainable aviation fuel that offers incentives to fuel that cuts emissions by at least 50% compared to standard jet fuel.

U.S. Energy Secretary Jennifer Granholm said that while a lot of progress has been made, getting to a fully decarbonized economy is going to require new technologies.

Washington is expanding efforts to make the state a leader in emissions-free aviation, Gov. Jay Inslee signaled at the Paris Air Show this week.

The governor signed climate bills related to sustainable aviation fuel, local land-use planning, transmission planning, pumped storage and more.

U.S. commercial aviation is charting an ambitious flight plan to net-zero emissions by 2050 using synthetic liquid fuels rather than batteries or fuel cells.

A legislative effort to make Washington more attractive to the alternative jet fuel industry has reached the state Senate’s Ways and Means Committee.

Commercial aviation can be carbon-free, say engineers and commercial airline planners who see the changes coming first in smaller electric aircraft.

Transportation electrification is the key theme at the BNEF Summit in San Francisco, and CEO Jon Moore opened the event with what's driving the transition.

Getting to 50% electric vehicle sales by 2030 won’t be easy, say Transportation Secretary Pete Buttigieg and Energy Secretary Jennifer Granholm.

Decarbonizing the hardest-to-decarbonize industries will likely entail learning lessons from past failures, according to panelists at the RFF summit.
