Cutting Emissions from Transportation

The transportation sector is the second largest source of U.S. GHG emissions, responsible for 28% of emissions nationally, and nearly 40% in Northeast and Mid-Atlantic states. Transportation fuels, notably gasoline and diesel, must be priced in a way that reflects the cost of these emissions, either through a carbon tax or the Regional Greenhouse Gas Initiative (RGGI), which currently regulates power plant emissions.

Acadia Center is working to change policies so they account for the full lifecycle of the greenhouse gas emissions fuels produce. Gasoline refined from tar sands, for example, has very high extraction emissions. Several different policies could address these upstream emissions, such as the Low Carbon Fuel Standard (LCFS) program in California. The LCFS sets targets for lowering the lifecycle carbon intensity of fuels and allows the market to determine the most cost-effective fuels and strategies for achieving those targets. A good initial step would be to require tracking and reporting by oil importers and wholesalers to allow states to determine how their fuel supplies are changing and what the best policy answer is.


Acadia Center is also advancing solutions to help reduce the upfront cost of electric vehicles (EVs), build out charging infrastructure and educate consumers on the benefits of EVs. It is possible to dramatically increase the adoption of EVs over the next few years.

Electrification of the vehicle fleet is one of the key pathways to cleaning up the transportation sector. Switching from a traditional car burning gasoline to a fully electric vehicle can reduce GHG emissions by 60% in the Northeast. As cleaner sources power the electric grid, these benefits will increase. In addition, vehicles running on electricity don’t emit any of the local pollutants that come from gas engines.

EVs save money, too. Switching from gasoline to electricity can cut per-mile costs significantly and allow consumers to spend more of their hard-earned dollars in local economies. Time-of-use rates will allow EV owners to save even more money by charging at night when the cost of generating electricity is low.

To seize the opportunity of EVs, the top priorities are to explore and address potential impacts on the power grid and maximize the ability of EVs to serve as a grid resource.


  • Direct Sales of Electric Vehicles in Connecticut

    Connecticut is debating whether to allow the direct sales of electric vehicles (EVs) by manufacturers, but concerns have been raised about potential impacts to employment at existing car dealerships. Acadia Center examined auto dealer employment statistics for nearby states that allow direct sales, and the results indicate that there has been no negative impact on this industry’s job levels or trends.

  • Strengthening RGGI to Improve Public Health

    As participating states weigh the future of the Regional Greenhouse Gas Initiative (RGGI), impacts on public health should be considered. The program’s success in reducing CO2 emissions to date has also led to avoided emissions of harmful co-pollutants, resulting in cleaner air and healthier people. Acadia Center analysis shows that the RGGI states can achieve billions of dollars in additional avoided health impacts by establishing an ambitious cap through 2030.

  • EnergyVision 2030

    Clean energy technologies offer an historic opportunity to build an energy future that produces large consumer, economic, and climate benefits. EnergyVision 2030 shows how, by redoubling existing efforts in four key areas, New York and the six New England states can accelerate this transition and achieve a modern, low-emissions energy future.
