The TPB and its members work to minimize greenhouse gasses emissions from the transportation sector. The region’s transportation agencies implement strategies and support transportation options that limit emissions to mitigate climate change. Planning for resiliency of the transportation system is also necessary to maintain and protect transportation infrastructure. While we’ve always experienced natural disasters, a changing climate is expected to increase the frequency, duration, and intensity of extreme weather.
When planning for transportation operations and investments, it is important to consider and mitigate any negative impacts on our environment, from the waters that are part of the Chesapeake Bay watershed to landcover and air. The TPB also partners with COG and its members on issues of environmental mitigation.

The TPB Climate Change Mitigation study of 2021 (2021) –The TPB undertook a scenario study, with consultant assistance, to assess ways to reduce greenhouse gas (GHG) emissions in the on-road transportation sector. The study assessed the types of transportation-related actions, and their levels of implementation, that would be needed to reduce GHG emissions to meet regional goals for 2030 and 2050. The region’s officials approved a new goal to reduce GHG emissions by 50 percent in 2030 relative to 2005 levels. Learn more.
The TPB Resiliency Study
The purpose of the TPB Resiliency Study is to advance regional planning for one of the federal Planning Factors, transportation resiliency and reliability, which is also one of TPB’s policy priorities.
- TPB Resiliency Study Memorandum: Inventory of TPB Member Recent Resiliency Planning Activities – The study team conducted research to document planning and capital-programming activities that the TPB member agencies and select partners are undertaking to prepare for the transportation system to be resilient in the face of natural disasters; These findings are summarized in the memorandum.
- TPB Resiliency Study Whitepaper – The study team developed a whitepaper that synthesizes the research findings. It documents regional vulnerabilities to natural hazards, discusses strategies for resilience, addresses equity in resiliency planning and the identifies potential MPO roles in future resilience planning efforts.
Transportation and Climate Initiative
The Transportation and Climate Initiative endorses the Transportation and Climate Initiative’s regional “cap and invest” policies and programs to further enable GHG emission reductions from transportation.
Environmental Consultation Environmental Inventory Mapping
- The National Capital Region Transportation Planning Board (TPB) is federally required to engage and consult with affected state and local environmental resource agencies regarding the development of the long-range transportation plan. This interactive map is used to inform about the relationship between the plan and regional-level environmental concerns by defining and inventorying environmental resources and data. The maps can serve as a tool to identify long-term regional mitigation strategies and high conservation priority or areas for potential restoration. These maps will be updated as part of the Visualize 2045 update. Map Detail | Metropolitan Washington Council of Governments (mwcog.org)
