Study from EDF and Black & Veatch aims to provide utilities and regulators with tools and strategies to support proactive grid planning for M/HDV distribution grid upgrades.

By Michael Zimmerman  A new study by Black & Veatch, commissioned by Environmental Defense Fund, provides further evidence that proactive grid investments don’t just help electric vehicles get on the road — they can save utility ratepayers money.  As EDF and many others have pointed out, traditional grid planning and investment processes were not designed …

America’s ports are hotbeds for toxic air pollution due to the diesel-powered ships and port vehicles that move our goods from sea to land. This pollution causes all kinds of health problems for nearby communities — from asthma and lung disease, to premature birth and death — which is why today’s announcement from the Environmental …

Order will further state charging goals and focuses on overburdened communities

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 …

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.

By Maaz Haider As the world grapples with the increasing frequency and intensity of natural disasters, the impacts of climate change have become a tangible concern for millions of people. Among the largest contributors to this crisis is transportation, the largest source of U.S. emissions, and medium- and heavy-duty vehicles have an outsized impact. Hence,

By Michael Zimmerman and Neda Deylami  The market for electric medium- and heavy-duty vehicles in the U.S. is rapidly expanding. As of October 2024, 11 states have adopted the Advanced Clean Trucks rule, which requires manufacturers to produce increasing amounts of zero-emission MHDVs, and more are considering adopting this standard. Key policies like the ACT …

EDF retained Atlas Public Policy to model, for 18 states plus the District of Columbia, the number of charging stations that would be needed in each state to meet ACT targets through 2032.

The coming months will be critical for member states to reach consensus on the design of economic and technical measures to decarbonize shipping.
