TRB’s National Cooperative Highway Research Program (NCHRP) Report 804: Guidebook for Designing and Managing Rights-of-Way for Carbon Sequestration and Biomass Generation explores the operational concerns, programmatic issues, and market conditions associated with utilizing highway rights-of-way (ROWs) to develop carbon sequestration projects. These projects are designed to generate saleable carbon offsets or to grow marketable biomass for sale into bioenergy markets.
