This data product is an assembly of best available and citable information from around the globe on current biomass uses, and potential for additional sustainable biomass supplies. This dataset was compiled through an inventory and review of current sources of data and biomass resource assessments, including recent (since 2018) national, regional, and global assessments. An initial list of assessments identified (report version 1) have been assembled based on outreach and literature review. This draft dataset is being distributed among stakeholders for comment, with the intent to produce a working list of resources (Inventory report version 2) to be considered in subsequent analysis and tasks.
