Renewable Carbon in LCA Guidelines (146 pages) evaluates methodological choices which impact LCAs for products containing renewable carbon in existing LCA frameworks and guidelines. The study specifically examines the similarities and differences in the methodological choices of guidelines, as well as the implications of these methodological aspects on the resulting LCA outcomes.The frameworks were selected based on their relevance and legitimacy in the industry, academia and policy field, and include: ISO 14040/44, ISO 14067, GHG Protocol Product Standard, PACT’s Pathfinder Framework, the PCF Guideline for the chemical industry by Together for Sustainability (TfS), EPD for the construction industry – ISO 14025 and EN 15804, the Renewable Energy Directive, the Product Environmental Footprint (PEF) and the JRC’s plastics LCA methodology. One field with a particularly large methodological freedom is recycling.
