Current corporate climate reporting frameworks, most notably the Greenhouse Gas (GHG) Protocol, inadequately capture the climate benefits generated by circular economy activities. While emissions from recycling, waste treatment, and secondary material production are fully accounted for within Scope 1–3, the positive climate effects arising from the substitution of primary materials and fossil energy carriers are largely excluded from corporate carbon accounts. As a result, companies operating in the waste management and circular economy sectors face a structural underrepresentation of their actual contribution to climate mitigation.
This contribution presents a scientifically grounded and practically applicable methodological framework for the transparent quantification and reporting of avoided emissions as a complementary reporting category, often referred to as “Scope 4.” The proposed approach builds on established principles from life cycle assessment (LCA), particularly waste management LCA, and adapts them to the context of corporate climate reporting. In contrast to prevailing approaches—such as those promoted by the World Business Council for Sustainable Development (WBCSD), which rely on hypothetical baseline scenarios—the framework follows an attributional logic based on real, observable material and energy flows.
Key methodological principles include causality, additionality, and functional equivalence (like-for-like substitution). Avoided emissions are calculated by quantifying the substitution effects of secondary materials and recovered energy, using clearly defined reference products and conservative substitution factors. The approach differentiates between Scope 1 and Scope 3 activities and avoids double counting by explicitly separating avoided emissions from the conventional GHG inventory. Importantly, avoided emissions are reported additively and not offset against a company’s own emissions.
The framework is applicable across multiple business areas of the circular economy, including material recycling, waste-to-energy processes, bio-waste treatment, and advisory services. By providing a transparent, conservative, and verifiable methodology, this contribution addresses a critical gap in corporate climate reporting. It provides a foundation for improved comparability, enhanced credibility, and a more accurate representation of the climate benefits of circular value chains. The framework is intended as a stepping stone toward the development of an industry-wide standard for avoided emissions reporting that aligns with existing climate governance and sustainability disclosure regimes.
