AASHTO’s Resilient and Sustainable Transportation Systems Technical Assistance Program (RSTS) is designed to help state DOTs understand the potential effects of climate change and the range of strategies and options for climate change mitigation and adaptation. The RSTS Steering Committee and the tasks being implemented by the Technical Assistance Program help achieve these goals. RSTS is a voluntary pooled-fund program that provides timely information, tools, and technical assistance to AASHTO members in meeting the difficult challenges that arise related to climate change, energy efficiency, energy security, infrastructure adaptation, alternative vehicles and fuels, and other relevant topics. This program is a critical resource for state DOTs to address climate change and energy issues, while also providing the information needed to engage in and influence climate change and energy developments at the federal level.
