Our Objective

Portsmouth TCAG (Transportation and Climate Action Group) is a group of residents committed to sustainable transportation in Portsmouth. TCAG is a subcommittee of Seacoast Climate Action Now (Seacoast CAN). Sustainable transportation provides safe and affordable travel options for all while protecting the environment and supporting a prosperous local economy. 

At 27% the transportation sector is the largest contributor to greenhouse gas emissions (GHG), according to the EPA. TCAG is developing ideas for low carbon transportation as input to the new Portsmouth Climate Action Plan (CAP) and researching best practice transportation strategies in CAPs in peer communities around the country.


Community Conversation

Community Conversation On Transportation, Smart Growth And Climate. June 29, 2023
Download the meeting summary

Portsmouth Smart Growth, Portsmouth Climate Action, and the Transportation and Climate Action Group cosponsored this conversation to discuss how transportation choices are major sources both of greenhouse gas emissions (20-30%) and potential reduction strategies. We addressed the question: Are there smart transportation and land use choices that reduce emissions, for example, by providing attractive and affordable new forms of mobility, make walking and biking safer, encourage electric vehicles, or improve accessibility choices for new development?

This is the first in a series of small and informal Community Conversations organized by Portsmouth grass roots organizations as part of community engagement for the Climate Action Plan (CAP). The conversations will address the urgency of the Climate Crisis through support for developing and implementing the CAP as individuals, neighborhoods, businesses, the city, and Seacoast region.

Slides illustrating the several presentations are available here. The program agenda may be viewed here.  For additional information:
