    Growth Energy backs EPA plan to reallocate 100% of SRE-lost gallons in 2025 RVOs

    Growth Energy commended the U.S. Environmental Protection Agency (EPA) for proposing to reallocate 100% of the difference between projected and actual exempted gallons lost to small refinery exemptions (SREs) in the 2025 renewable volume obligations (RVOs) under the Renewable Fuel Standard. In August, EPA announced a plan to grant 29 SREs from the 2025 RVO, while pledging to fully account for any lost demand before the end of October. Growth Energy CEO Emily Skor said reallocating the lost gallons would strengthen the rural economy and give farmers reliable new markets, and credited congressional champions and USDA Secretary Rollins for supporting biofuel growth.

    Aviation roadmaps overshoot planetary limits, Nature Communications study finds

    A study published in Nature Communications finds that none of the currently proposed aviation roadmaps for climate mitigation bring the sector within its share of Earth's planetary boundaries. Assessing scenarios from ICAO, ATAG and the EU's ReFuelEU Aviation initiative, the authors find systematic transgression of the two core boundaries, climate change and biosphere integrity, regardless of storyline, allocation principle or biofuel production pathway. Historical aviation impacts from 1940 to 2022 alone already transgress those boundaries under the ethics-based allocation. Beyond 2022, fossil kerosene drives the transgression, while the environmental burdens of biofuels and e-fuels are highly sensitive to production pathways. The authors conclude that technological improvements alone are insufficient and that combined actions including ambitious demand-side measures are required. Under the study's scenarios, air traffic would need to degrow by 8.6% per year for additional planetary boundaries to be respected.
