California scraps green trucking mandates after legal challenges, shifting environmental policy, and affecting trucking businesses statewide. Learn what this means for your compliance with environmental and transport laws.
California regulators have officially dropped their controversial green trucking mandates following a lengthy legal battle. This development marks a major shift in the state’s environmental policy for commercial trucking and will impact both transport companies and environmental advocates. The reversal comes after a lawsuit from a group linked to former U.S. Attorney General Bill Barr, putting the brakes on what would have been a revolutionary green trucking requirement for California’s big-rig fleet.
What Were the Green Trucking Mandates?
The California Air Resources Board (CARB) had implemented a series of green trucking rules designed to reduce carbon emissions and shift the commercial trucking industry toward zero-emission vehicles. One of the most prominent mandates would have required all new big-rig trucks to be zero-emission starting in 2036, with full compliance across fleets by 2042.
The state positioned these mandates as a critical move to fight climate change and meet federal air quality standards. However, the trucking industry raised serious concerns about infrastructure, cost, and the practicality of enforcing such rules within the proposed timeline.
Legal Challenge Halts Green Trucking Rollout
Legal opposition emerged from the American Fuel & Petrochemical Manufacturers (AFPM), along with the Western States Trucking Association. Represented by a legal team linked to former Attorney General Bill Barr, the group argued that California’s mandates overstepped state authority and conflicted with federal law under the Clean Air Act.
After the Environmental Protection Agency (EPA) hesitated to support California’s waiver in court, CARB dropped its defense. In June 2024, the state formally ended its enforcement of the mandates to avoid a likely legal defeat.
A related report by the Associated Press further highlighted that the U.S. House of Representatives recently passed a resolution aiming to block California’s vehicle emissions rules entirely, reinforcing growing federal opposition.
What This Means for California Businesses
With the rollback of green trucking rules, California businesses that rely on commercial transport operations will see immediate changes. Here’s what to consider:
1. Short-Term Regulatory Relief
Fleet operators no longer face the pressure of meeting the strict 2036 or 2042 benchmarks. Companies can now reevaluate budgets that included expensive electric truck investments and infrastructure upgrades.
2. Ongoing Policy Uncertainty
While enforcement has paused, California’s environmental goals remain. The state may introduce revised or restructured mandates in the near future. Businesses should remain informed and adaptive to new developments in green trucking legislation.
3. Legal Precedents on Federal Preemption
This case reaffirms limits on state authority under federal environmental laws. Other states considering similar mandates may proceed with caution, especially in areas where federal rules are dominant.

Environmental Implications of the Rollback
Environmental groups have criticized the decision, arguing that California’s withdrawal will slow progress in reducing pollution and public health hazards, especially in communities near busy freight corridors.
The Natural Resources Defense Council (NRDC) and other advocacy groups warn that the rollback could contribute to worsening climate conditions and delay the adoption of clean technologies. In the long run, such shifts may also affect California’s credibility as a leader in clean transportation.
Federal vs. State Authority: A Legal Balancing Act
The federal Clean Air Act allows California to set stricter emissions rules if granted a waiver by the EPA. Historically, the EPA has supported California’s environmental innovations. However, the agency’s recent hesitation to defend the trucking mandates signals possible changes in federal policy direction.
This creates a legal gray zone for businesses, especially those operating across state lines. Coordinated guidance from legal experts can be essential in mitigating risk and ensuring lawful operations during periods of regulatory flux.
