(Reference Rhode Island General Laws 31-47.3-3)
Zero Emission Vehicle (ZEV) Sales Requirements and Low Emission Vehicle (LEV) Standards
Rhode Island has adopted the California motor vehicle emissions standards and compliance requirements specified in Title 13 of the California Code of Regulations. These regulations apply to passenger vehicles, light-duty trucks, and medium-duty vehicles. Manufacturers must meet the greenhouse gas emissions standard and the ZEV production and sales requirements. (Reference Rhode Island Department of Environmental Management Regulation No. 37)
Alternative Fuel Vehicle (AFV) and Zero Emission Vehicle (ZEV) Acquisition Requirements
To reduce fuel consumption and pollution emissions, and purchase vehicles that provide the best value on a life cycle cost basis, the state must take the following actions:
- At least 75% of state motor vehicle acquisitions must be AFVs, and the remaining 25% must be HEVs to the greatest extent possible. By 2025, 25% of state motor vehicle acquisitions must be ZEVs;
- All new light-duty trucks in the state fleet must achieve a minimum city fuel economy of 19 miles per gallon (mpg) and achieve at least a Low Emission Vehicle certification, and all new passenger vehicles in the state fleet must achieve a minimum city fuel economy of 23 mpg;
- All state agencies must purchase the most economical, fuel-efficient, and lowest emission vehicles appropriate to meet requirements and discourage the purchase of sport utility vehicles;
- All state agencies must purchase low rolling resistance tires with superior tread life for state vehicles when possible; and
- All state vehicles must be maintained according to manufacturer specifications, including specified tire pressures and ratings.
State Agency Coordination to Address Climate Change
The Rhode Island Executive Climate Change Coordinating Council (EC4) was established to coordinate efforts between state agencies to reduce greenhouse gas (GHG) emissions. The Council will pursue GHG emissions reductions of 10% below 1990 levels by 2020, 45% below 1990 levels by 2035, and 80% below 1990 levels by 2050. With assistance from the Council, state agencies will develop programs to encourage state employees to reduce vehicle miles traveled and use public transportation when available. The Council will also work with municipalities to encourage sustainability; identify federal, state, and private funding opportunities that can be leveraged to reduce emissions in Rhode Island; and develop GHG emissions reduction strategies. The Council submitted a plan in December 2016 with suggested strategies for GHG emissions reduction activities to the governor. (Reference Rhode Island General Laws 42-6.2)
Zero Emission Vehicle (ZEV) Deployment Support
Rhode Island joined California, Connecticut, Maryland, Massachusetts, New Jersey, New York, Oregon, 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.
For more information, see the Multi-State ZEV Task Force website.
Petroleum Reduction Initiative
The Petroleum Savings and Independence Advisory Commission (Commission) was established to provide recommendations and monitor programs designed to reduce the state's dependence on petroleum-based fuels in the transportation and heating sectors. Established targets may not provide less than a 30% overall reduction in petroleum consumption from 2007 levels by 2030 and a 50% overall reduction from 2007 levels by 2050. Recommendations will include those related to incentives, plug-in electric vehicle deployment, implementation of a clean fuels standard, and land use planning. The Commission must report on monitoring activities to the General Assembly at least every two years. The Commission must also continue to evaluate the state's progress toward meeting petroleum-reduction goals and make recommendations to the General Assembly as necessary. (Reference Rhode Island General Laws 42-140.4)
Idle Reduction Requirement
Motor vehicles may not idle unnecessarily for longer than five consecutive minutes during any 60-minute period. This includes heavy-duty diesel vehicles used to perform any state public works contracts. Unnecessary idling does not include circumstances exempted by regulations the Rhode Island Department of Environmental Management (DEM) has adopted, such as when it is necessary to operate heating and cooling equipment to ensure the health or safety of drivers and passengers. Other vehicles exempt from these requirements include, but are not limited to, the following: 1) emergency response, public safety, or military vehicles; 2) armored vehicles being loaded or unloaded; 3) non-road vehicles; and 4) vehicles making deliveries of fuel or energy products.
