ISCC PLUS is an international certification program under the ISCC (International Sustainability and Carbon Certification) system for non-regulated markets. It verifies the sustainability and traceability of circular and bio‑based materials across global supply chains, with broad adoption in the chemicals, plastics, packaging, food, and consumer goods sectors.
The scheme covers chain‑of‑custody options such as mass balance and physical segregation, enabling credible claims on recycled and bio‑circular content from point of origin to final product. Certification is based on independent third‑party audits and includes requirements for material traceability, documentation, and greenhouse gas calculation and reporting. ISCC PLUS helps companies demonstrate conformity with circular economy and responsible sourcing objectives throughout the chemical industry value chain.
