Proposed safeguards in Washington State’s Clean Fuel Standard are crucial
If adopted as written, Washington State’s SB 5601 could endanger the effectiveness of the state’s Clean Fuel Standard.
How upstream methane leakage further weakens the argument for natural gas trucks
Natural gas trucks’ greenhouse gas benefits are marginal when accounting for methane leakage—and could lock out better zero-emission alternatives.
Delays in California’s LCFS revisions are an opportunity to improve
Using the time made available by a delay in revisions to add guardrails such as a cap on lipids and greater restrictions on the crediting and deliverability of biomethane would help align the LCFS with California’s climate goals.
The case for a lipids cap in California’s Low Carbon Fuel Standard
Explores the increases in U.S. imports of used cooking oil (UCO), driven by policies incentivizing low-carbon intensity fuels like California’s Low Carbon Fuel Standard (LCFS).
The price of green hydrogen: How and why we estimate future production costs
With green hydrogen in its infancy, production cost estimates guide our understanding of where it can become a cost-effective solution.
Revisions to the EU ETS set a global model for sustainable aviation fuel investment
The EU introduced a re-investment mechanism to reduce the cost gap between sustainable aviation fuel (SAF) and fossil jet fuel using funds from the EU Emissions Trading System (ETS). This scheme sets an example for other regions seeking to incentivize SAF that delivers the biggest climate benefit.
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.
The risks of betting on biofuels with flex-fuel plug-in hybrid cars in Brazil
Explores the greenhouse gas emissions risks associated with using flex-fuel plug-in hybrid cars with biofuels in Brazil as an alternative to battery electric vehicles in the context of the country’s climate goals.
Os riscos da aposta em carros híbridos plug-in flex-fuel no Brasil
Explora os riscos associados ao uso de carros híbridos plug-in flex com biocombustíveis no Brasil como uma alternativa aos veículos elétricos a bateria (BEVs) no contexto das metas climáticas do país.
Aligning the IMO’s Greenhouse Gas Fuel Standard with its GHG strategy and the Paris Agreement
Explores how the GHG Fuel Standard (GFS) can be designed to align with the International Maritime Organization’s (IMO) GHG strategy and the Paris Agreement.
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.
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
