International Sustainability and Carbon Certification PLUS

As global supply chains move towards greater transparency and sustainability, organisations across various industries are under increasing pressure to demonstrate responsible sourcing, traceability, and environmental performance. Beyond regulatory compliance, sustainability has become a key driver of customer trust, brand reputation, and long-term business resilience.

This is where ISCC PLUS (International Sustainability and Carbon Certification PLUS) plays an important role.

ISCC PLUS is a globally recognised sustainability certification system designed for non-regulated markets, enabling organisations to verify and communicate sustainable sourcing practices across a wide range of materials and products. It is widely adopted in industries such as chemicals, plastics, packaging, food and feed, cosmetics, and bio-based materials.

ISCC PLUS is a voluntary sustainability certification scheme developed by ISCC, focusing on supply chain transparency, responsible sourcing, and traceability beyond the scope of regulatory frameworks such as the EU Renewable Energy Directive.

Unlike ISCC EU, which is linked to regulatory compliance for renewable energy, ISCC PLUS is market-driven. It allows organisations to demonstrate sustainability credentials for products supplied to voluntary and commercial markets.

ISCC PLUS applies to a broad range of materials, including:

• Bio-based and circular materials

• Recycled and renewable feedstocks

• Agricultural and forestry products

• Chemical intermediates and polymers

• Food and feed ingredients

The certification covers the entire supply chain, from raw material origin to processing, trading, and final product.

Traceability and Chain of Custody

• Full traceability of materials throughout the supply chain

• Mass balance, physical segregation, or book & claim models

• Prevention of double counting and misrepresentation

Supply Chain Transparency

• Clear documentation of material flows

• Verification of sustainability claims

• Robust record-keeping and data management

Greenhouse Gas (GHG) Emissions (Optional)

• GHG data reporting (where applicable)

• Support for carbon footprint and climate reporting initiatives

These elements ensure that sustainability claims are credible, verifiable, and aligned with international best practices.
