Alternative Fuel and Fuel-Efficient Vehicle Acquisition and Emissions Reduction Requirements

Cars and light-duty trucks purchased by state agencies must meet the following requirements:

• Have an average U.S. Environmental Protection Agency estimated fuel economy of at least 40 miles per gallon;
• Comply with state fleet vehicle acquisition requirements set forth under the Energy Policy Act of 1992 (EPAct); and
• Obtain the best achievable fuel economy per pound of carbon dioxide emitted for the applicable vehicle classes.

In addition, all cars and light-duty trucks that the state purchases or leases must be hybrid electric vehicles, plug-in hybrid electric vehicles, or capable of using alternative fuel. All AFVs purchased or leased must be certified to the California Air Resources Board's (ARB) Ultra Low Emission Vehicle II (ULEV II) standard, and all light-duty gasoline vehicles and hybrid electric vehicles the state purchases or leases must be certified, at a minimum, to the California ARB ULEV II standard. The Connecticut Department of Administrative Services must report annually on the composition of the state fleet, including the volume of alternative fuels used.

Vehicles that the Connecticut Department of Public Safety designates as necessary for the Department of Public Safety to carry out its mission are exempt from these provisions.

School Bus Emissions Reduction

Each full-sized school bus with a Model Year (MY) 1994 or newer engine must be equipped with specific emissions control systems, including either: a closed crankcase filtration system and a level 1, level 2, or level 3 device; an engine that the U.S. Environmental Protection Agency (EPA) has certified as meeting MY 2007 emissions standards; or use of compressed natural gas or other alternative fuel that EPA or the California Air Resources Board has certified to reduce particulate matter emissions by at least 85% as compared to ultra-low sulfur diesel fuel. (Reference Connecticut General Statutes 14-164o)

Zero Emissions Bus Implementation Plan

As part of a state effort to identify strategies to expand the availability and use of hydrogen fuel and renewable energy sources, the Connecticut Department of Transportation, in consultation with the Connecticut Center for Advanced Technology, developed the Connecticut Hydrogen and Fuel Cell Deployment Transportation Strategy: 2011-2050. The strategy includes a plan to implement zero emissions buses on a state-wide basis and addresses the technological, facility, and financial arrangements necessary to fully implement a zero emissions bus fleet, including identifying specific locations for hydrogen fueling stations along state highways and other locations. (Reference Connecticut General Statutes 13b-38dd)

Zero Emission Vehicle (ZEV) Deployment Support

Connecticut joined California, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, and Vermont in signing a memorandum of understanding (MOU) to support the deployment of ZEVs through involvement in a ZEV Program Implementation Task Force (Task Force). In May 2014, the Task Force published a ZEV Action Plan (Plan) identifying 11 priority actions to accomplish the goals of the MOU, including deploying at least 3.3 million ZEVs and adequate fueling infrastructure within the signatory states by 2025. The Plan also includes a research agenda to inform future actions. On an annual basis, each state must report on the number of registered ZEVs, the number of public electric vehicle supply equipment (EVSE) and hydrogen fueling stations, and available information regarding workplace fueling for ZEVs.

In June 2018, the Task Force published a new ZEV Action Plan for 2018-2021. Building on the 2014 Action Plan, the 2018 Action Plan makes recommendations for states and other key partners in five priority areas:

• Raising consumer awareness and interest in electric vehicle technology;
• Building out a reliable and convenient residential, workplace and public charging/fueling infrastructure network;
• Continuing and improving access to consumer purchase and non-financial incentives;
• Expanding public and private sector fleet adoption; and
• Supporting dealership efforts to increase ZEV sales.

Hydrogen and Plug-In Electric Vehicle (PEV) Rebate

The Hydrogen and Electric Automobile Purchase Rebate Program (CHEAPR) offers rebates for the incremental cost of the purchase or lease of a hydrogen fuel cell electric vehicle (FCEV), all-electric vehicle (EV), or plug-in hybrid electric vehicle (PHEV). Rebates are offered based on battery range in the following amounts:

Rebates are offered on a first-come, first-served basis until funds expire. For more information, see the Connecticut Department of Energy and Environmental Protection EV Connecticut website.

Electric Vehicle (EV) Registration Data

By January 1, 2018, the Department of Motor Vehicles (Department) must record the number of EVs registered in Connecticut. An EV is defined as any battery electric, fuel cell, plug-in hybrid, or range-extended battery electric vehicle. The data should be publicly available on the Department's website and include the number of EVs registered in state each year, and the total number of EVs registered in the state. The Department must update the information every six months. (Reference Connecticut General Statutes 14-12)
