This report finds that biogas-based biofuels can provide strong support for decarbonization of shipping, especially in the early stages of the transition. Biogas-based biofuels can extract value from diverse feedstocks, including waste, and can be produced at scale via technologies and supporting infrastructure that are either already commercially available or will likely become so in the near future. Emerging virtual infrastructure, such as green certificates trading or book and claim systems, could further enhance the sustainability and business cases for these biofuels. However, control of methane emissions throughout the value chain emerges as an important challenge for this sector’s environmental sustain
