As climate awareness continues to grow, many states are taking matters into their own hands. In 2005, a collection of states established the Regional Greenhouse Gas Initiative (RGGI) to curb emissions in the power sector. Using RGGI as a springboard, the Transportation and Climate Initiative (TCI) was formed five years later to mitigate emissions in the transportation sector. In Maine, the transportation sector is responsible for 53% of the state’s carbon dioxide emissions, making it an important target for emission reductions. This policy brief is a summary of our research examining the differential effects of the TCI-P on rural and urban households in Maine.
