Clean Transportation

Our region's rapid growth has put a strain on our transportation system and our environment. Vehicles in Southern Maine are the single largest source of greenhouse gas emissions in the state, and our transportation infrastructure faces a multitude of challenges, such as:

  • Aging public transportation fleets
  • Deteriorating roads and bridges
  • Growing traffic
  • Limited transportation options for large rural areas


The Greater Portland Council of Governments (GPCOG) is working to provide Clean Transportation options to address many of our ongoing issues, through:

  • Promoting the use of alternative transportation fuels and vehicles to reduce petroleum consumption, emissions and energy costs
  • Supporting the seven transit agencies serving Greater Portland in their efforts to decrease the number of vehicles on the road and increase use of public transportation through improved service and coordination
  • Working with our members on active transportation planning to help develop walkable and bikeable neighborhoods that are less dependent on personal automobiles
