The Clean Fuels Alliance America has filed a lawsuit against the EPA for not adequately considering the use of biodiesel and renewable diesel in heavy-duty truck regulations. This lawsuit challenges the EPA's Phase 3 greenhouse gas emissions standards rule, which aims to enforce stricter emission limits on commercial vehicles through 2032. Critics argue that the rule favors technologies like electric and fuel cell trucks over biofuels that are readily available and cost-effective. Farmers and industry leaders are concerned that the regulations could impact efficiency and safety in long-distance transportation. The lawsuit raises important questions about the balance between environmental goals and practicality in the transportation sector.
