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 83^rd 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.

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 will be essential to ensuring customers’ access to zero-emission trucks and buses.

As medium- and heavy-duty vehicles speed toward electrification, the build-out of charging infrastructure must keep pace. How utilities incorporate transportation into foundational utility functions will inform where, when, and how fast electric vehicles come online. These decisions fall mainly under the authority of state utility regulators (Public Utility Commissions) rather than transportation regulators. Therefore, advocates interested in supporting MHDV electrification should engage with PUCs in addition to more traditional advocacy avenues such as legislation.

Transportation accounts for 24% of greenhouse gas emissions in Texas. Throughout the state, areas with the greatest concentration of traffic are often found to be in nonattainment — a designation from the Environmental Protection Agency that pollution levels exceed air quality standards. Texas’ cities can engage in transportation and environmental planning that reduces pollution and improves health outcomes for communities around the state.
