A Tale of Two Basins: Colorado regional oil and gas pollution differences highlight need for action on the West Slope

By Nini Gu

Data recently collected by EDF’s MethaneAIR project in 2023 reveals a striking difference in the emissions profiles between the two major Colorado basins: the Denver-Julesburg (D-J) in the east, and the Piceance in the west. The D-J Basin exhibited a 1.7% methane loss rate from the total natural gas produced; by contrast, the loss rate for the Piceance Basin hit 7%, a high figure among all surveyed basins.

Affordable aviation e-fuels are on the horizon

By Pedro Piris-Cabezas and Glenda Chen

The adoption of electricity-based synthetic fuels, also known as e-fuels, will be essential for any hard-to-decarbonize sector with a stake in a resilient liquid fuels market. Chief among them is aviation.

Financing provides Japan another lever to reduce global oil & gas industry emissions

By Hiro Shirakawa

As one of the world’s top five importers and financiers of oil and natural gas, Japan is uniquely positioned to influence methane emissions along the supply chain.

Though Japan has been recognized for the climate-action leverage it can exert as a major global buyer of liquefied natural gas, a new Deloitte report commissioned by Environmental Defense Fund highlights an equally powerful tool: Japan’s substantial financial investments in oil- and gas-producing companies abroad.

Fleet stories on the road to electrification

By Kae Tuitt and Lindsay Shigetomi

Fleet electrification comes with unique challenges, yet fleets are finding ways to overcome these obstacles and put zero-emission vehicles on the road because the benefits are worth it. A zero-emission fleet leads to less air pollution, improved community health, new business prospects and financial savings such as lower maintenance and operational costs. According to an Environmental Defense Fund analysis, more than five times the amount of medium- and heavy-duty EVs were put into service in 2023 than in the previous year. Despite the challenges, businesses are leading the charge to successfully deploy EVs into their operations in pursuit of a zero-emission future.

New study shows the charging feasibility of the ACT in Illinois

By Neda Deylami

Adopting the Advanced Clean Trucks rule and transitioning Illinois’ trucks from diesel engines to zero-emission motors is one of the most powerful opportunities to reduce climate and air pollution, spark economic growth, prioritize equitable outcomes and improve health in the state. 

A new study from EDF and Atlas Public Policy modeled the charging infrastructure needed at depots and along truck routes to support the adoption of the Advanced Clean Trucks rule in Illinois through 2032.

Fair winds to a fair transition: the shipping sector must chart a new course

By Erica Morehouse

In April 2025, International Maritime Organization member states must come to a collective decision on technical and economic measures at the U.N. agency’s 83rd Marine Environment Protection Committee  meeting. The adoption of these measures will define the shipping industry’s trajectory toward net-zero greenhouse gas emissions and away from fossil fuels by 2050. These policies include a carbon pricing mechanism — which would require industry to pay a specific amount for each ton of greenhouse gas emissions – and a global fuel standard accounting for emissions at every stage of the shipping process. The measures are intended to incentivize and accelerate the adoption of new, lower carbon fuel technologies, and provide revenue for re-investment into the shipping sector’s transition, with justice and equity at the center.
