The consortium has advanced spatial- and temporal-explicit approaches to assess land use and land-management change (LUC/LMC) impacts driven by biomass demand. A retrospective method builds on IPCC guidance to quantify carbon stock changes across above-/below-ground biomass, dead organic matter and soils, linking effects to product systems despite forest multifunctionality. In parallel, a forward-looking ex-ante modelling framework combines a global economic model for demand scenarios, a spatial forest model for land transitions and management, and a spatial techno-economic model to map biomass flows to processing and products (GLOBIOM, G4M, BeWhere). This enables attribution of carbon impacts to specific harvested wood products under alternative futures and supports spatially and temporally explicit assessments of how increased biomass demand affects forestland area, management practices and carbon stock changes.
Dynamic inventory modelling for biobased systems with high spatial-temporal resolution has been developed, prioritising forest systems due to methodological inconsistencies in current practice. The draft procedure and guidance address the temporal dynamics of biogenic carbon removals, storage and delayed emissions, proposing a landscape-level accounting consistent with LULUCF carbon pools (SOC, AGB, BGB, DOM, HWP). An advanced case study with an industrial partner is underway to test the framework on cellulose fibre products sourced from two contrasting regions (Brazil and Austria).
On circularity, a systematic literature review screened 328 sources, analysed 66 in depth and identified 73 Circularity Assessment Indicators (CAIs). The analysis reveals gaps on renewable sourcing, cascading use and nutrient recovery, limited distinction between biotic and abiotic materials, and scarce integration of functional value. A refined indicator shortlist was proposed to guide further development of a circularity methodology grounded in life-cycle thinking.
To support a coherent sustainability assessment, more than 60 publications were reviewed as input to a consolidated methodology. Engagement with ISO (ISO 14000 series) and the Product Environmental Footprint Technical Advisory Board is ongoing to align methodological developments with current European and international guidance. Industry interviews (Stora Enso, Lenzing, GrownBio, Unilin) have elicited needs, tools and data availability.
