How crediting manure application at farms can get sloppy for fuels policy
Explores the complexities and risks associated with crediting manure application to cropland as a carbon sequestration strategy within U.S. sustainable aviation fuel (SAF) policy.
How Treasury’s recent guidance on the sustainable aviation fuel tax credit punted on which LCA methods are fit for takeoff
U.S. Treasury’s recent guidance provides little clarity on how life-cycle greenhouse gas (GHG) emissions will be calculated for different SAFs, and here are three upcoming decisions to look out for.
How the long shadow of model inputs could dilute the ambition of the Biden Administration’s SAF Grand Challenge
Explore how U.S. airlines and ethanol producers are seeking to alter the way greenhouse gas emissions from sustainable aviation fuels are calculated, which may affect the Biden Administration’s efforts to reduce emissions.
Gray, blue, or moo hydrogen? How gas companies are milking California’s LCFS
Avoided methane emissions from out-of-state dairy farms are fueling a burgeoning shadow carbon offsetting scheme within the California LCFS
For Canada’s Clean Fuel Standard, not all wood is good
Although the solid fuel pool is expected to be the smallest contributor to the proposed Clean Fuels Standard’s broader target, its implementation could have a substantial effect on the climate impact of the program overall.
How low-carbon fuel standards can support transport electrification
A variety of policies have been deployed at the state and federal levels to address higher up-front costs of EVs and concerns about sufficient charging infrastructure.
On alternative fuels, the House Climate Crisis Action Plan doesn’t think big enough
The proposed low-carbon fuel standard, although well-intentioned, may double down on past mistakes
Canada’s clean fuels standard is increasingly out of sync with Canada’s climate ambitions
Canada’s proposed Clean Fuels Standard has slowly morphed from a policy supporting the deployment of alternative fuels to one that largely supports the fossil fuel status quo.
Supersonic air travel: Moving away from our climate commitments, faster than ever
While it is likely that supersonic airplanes consume fuel at a greater rate than their conventional counterparts, could that extra fuel burn be mitigated through the use of alternative fuels?
Can India Leapfrog First-Generation Biofuels?
India’s biofuel policy update discourages food-based fuels, focusing instead on increasing production of second-generation biofuels made from wastes and inedible energy crops.
Failure to Launch: Why Advanced Biorefineries Are So Slow to Ramp Up Production
Despite claims that advanced biofuels are just a few years away from commercialization, existing projects struggle to reach their nominal capacity.
Can alternative jet fuels crowd out demand from the road sector?
Proponents of alternative jet fuels often ignore the reality that many other sectors have laid claims to limited bio-resources as part of their own decarbonization strategies
