This group explores biomass best practices and ensures biomass is properly and sustainably sourced.


This group has not yet set regular meetings for Members and Solutions Providers. Look for updates in the second half of 2022.

Working Group Members

All RTC Members and Solutions Providers with an interest in bio-based renewable thermal products.

Selected Publications

The initial product of this work was a global warming potential (GWP) Bio tool available as an Excel download.

Workstream Activity

Workstream activity is on hold as the RTC awaits updated greenhouse gas accounting rules from the World Resources Institute (WRI) expected to be released in the second half of 2022. When the working group convenes, it will seek clarity on how various biomass products will be treated in the protocol.

Selected Past Events

The World Wildlife Fund, a co-convener of the RTC, hosted a webinar to review the GWP Bio tool.
