The Healey administration announced on Friday that it will temporarily suspend enforcement of minimum electric vehicle (EV) sales requirements for model years 2026 and 2027. This decision comes as vehicle manufacturers are expected to produce an increasing percentage of zero-emission vehicles under the Advanced Clean Cars II (ACC II) regulation, which Massachusetts adopted in 2023 following California’s lead.
Background on ACC II Regulation
The ACC II regulation mandates that vehicle manufacturers gradually increase their production of zero-emission vehicles, starting at 35% in model year 2026, rising to 43% in model year 2027, and eventually reaching 100% by model year 2035. However, the Department of Environmental Protection (MassDEP) stated that it “will exercise enforcement discretion” for the first two years, effectively giving manufacturers more flexibility in their production and distribution.
Administration’s Rationale
“EVs should be the most affordable and clean option for cars,” said Governor Maura Healey. “We’re giving carmakers more runway to invest in their manufacturing and supply chains, which will help ensure customers have additional affordable electric vehicles options at dealerships in the future.” The administration also emphasized its commitment to continuing investments in charging infrastructure to support the widespread adoption of electric vehicles.
Legislative Context and Reactions
The decision to delay implementation of the ACC II regulations has been a topic of debate in the legislature. Recently, amendments to the spending bills have been proposed to delay the implementation for two years. Millbury Senator Michael Moore had filed such an amendment, highlighting the potential economic consequences of enforcing the rules when demand for electric vehicles and charging infrastructure lag behind expectations.
“By enforcing this rule, manufacturers will have to artificially manipulate vehicle inventory to force more zero-emission vehicles into the state while reducing the number of gas-powered vehicles available,” Moore explained. Senate Minority Leader Bruce Tarr also called for a two-year delay, citing concerns about the readiness of the electric grid and consumer demand.
Environmental Advocates’ Response
Environmental advocates have criticized the MassDEP’s decision. David Melly, Legislative Director of the Environmental League of Massachusetts, expressed disappointment, stating that the decision “causes delays that will harm our communities and the environment.” He emphasized the importance of timely progress on vehicle electrification to reduce transportation emissions and healthcare costs.
Future Plans and Commitments
In response to the criticism, the Healey administration announced plans to soon dedicate additional grant funding for the purchase or lease of electric vehicles for publicly owned fleets and other vocational vehicles. They also previewed enhanced future grant funding opportunities for various charging infrastructure projects through the MassEVIP program.
The decision reflects a balance between environmental goals and economic realities, as the state navigates the transition to cleaner transportation options.
