Twelve produces first batch of E-Jet fuel from CO2 electrolysis; partnership with USAF; electrifying fuel, not planes

Green Car Congress

Carbon transformation company Twelve (formerly Opus 12, earlier post ) has produced the first fossil-free jet fuel—called E-Jet—from CO 2 electrolysis, demonstrating a scalable, energy-efficient path to the de-fossilization of global aviation. Global aviation produces 1.2

Audi aims to reduce CO2 emissions by 30% over the vehicle lifecycle by 2025

Green Car Congress

Audi has set the goal of successively reducing vehicle-specific CO 2 emissions by 30% by 2025 compared with reference year 2015 and over the entire product lifecycle. In the long term, Audi is pursuing the vision of CO2-neutral mobility and aims to be climate-neutral throughout the company on balance by 2050. 97.9 - 111.9

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

In the study, the Ford team derived regional CO 2 targets for new LDVs while still providing an integrated view of the global LDV fleet—a perspective critical to the planning needs for global automotive firms. They refer to these emission trajectories as the global CO 2 caps. The cumulative CO 2 emissions 2000?2060

U-Mich researcher’s first-principles analysis challenges conventional carbon accounting for biofuels; implications for climate policy

Green Car Congress

In a paper that could have a significant impact on climate policies for transportation fuels, Dr. John M. As commonly used for energy policy, lifecycle analysis (LCA) calculates trajectories of GHG fluxes for specified bioenergy product systems in comparison to reference fossil-based systems.
