US rolls back emissions rules, reshaping the future of cars and trucks

A recent repeal of key environmental regulations is set to reshape the automotive industry in the US. Congress has removed penalties for failing to meet fuel economy targets, while also ending greenhouse gas standards for automakers. These changes follow the elimination of the EPA's 2009 endangerment finding, which had underpinned emissions rules for years.

The shift comes as part of the One Big Beautiful Bill Act, which zeroed out fines for automakers missing Corporate Average Fuel Economy (CAFE) goals. This move could reduce pressure on manufacturers to prioritise fuel-efficient or electric vehicles. Instead, companies may focus more on high-margin models like full-size trucks and SUVs—segments already seeing rising sales.

The repeal's impact will stretch beyond just vehicle types. Technologies designed to improve efficiency, such as stop-start systems, waste heat recovery, and solar-reflective coatings, may now be phased out. These changes won't happen overnight, though. Automakers will adjust production over several model years, balancing profitability with evolving market demands.

Despite the regulatory rollback, electric and hybrid vehicles aren't disappearing. Ford continues developing new EV news, while Toyota plans to make 70% of its US sales electrified by 2030. Hybrid options, in particular, remain a focus, with Toyota expanding its lineup for 2026. Ford, however, is still assessing how the repeal will affect its long-term strategy.

The EU, meanwhile, maintains stricter emissions news. Since 2020, targets have tightened, with a 2025 fleet average of 92.9 g/km CO₂ for brands like BMW. The bloc's 2035 goal—a 100% zero-emission requirement for new cars—contrasts sharply with the US approach. Adjustments in 2025 will allow some flexibility, but the overall direction remains clear: Europe is pushing harder for cleaner vehicles than the US currently is.

The repeal gives automakers more freedom to shape their lineups around profitability, particularly for larger, less efficient vehicles. Yet, with companies like Ford and Toyota still investing in electrification, the market may not abandon greener options entirely. The full effects will unfold gradually, as manufacturers adapt to the new rules over the coming years.
