This document provides the requirements for low ILUC risk certification for feedstocks and offers guidance for their implementation and verification for farms/plantations and first gathering points (FGPs).

The requirements described in this document apply to all elements of the supply chain of sustainable materials that have to be covered by certification (farms or plantations, point of origins of wastes and residues, first gathering points, central offices, collecting points for waste and residues, processing units, and traders and storage facilities).

The purpose of the document “Greenhouse Gas Emissions” is to explain the options for stating greenhouse gas (GHG) emission values along the supply chain and to provide the methodology, rules and guidelines for calculating and verifying GHG emissions and emission reductions.

The scope of this document covers the requirements on how the risk management process under ISCC is applied to all activities of ISCC and the implications of risks for ISCC audits.

The purpose of the document to explain the GHG calculation requirements for RFNBOs and RCFs, based on the Commission Delegated Regulation (EU) that specifies a methodology for assessing the greenhouse gas emissions savings from RFNBOs and RCFs.

ISCC EU Renewable Fuels of Non-Biological Origin (RFNBOs) and Recycled Carbon Fuels (RCFs) certification approach has been positively assessed by the European Commission (EC), official recognition by the EC is still pending. 

ISCC PLUS

Please note that the ISCC EU System Documents also serve as system documents for the ISCC PLUS scheme. The few differences and requirements that are specific to ISCC PLUS are described in the ISCC PLUS System Document, which is an additional compulsory source of information to the ISCC EU System Documents for a certification under ISCC PLUS.

This document presents the ISCC PLUS certification system, including governance, system basics and the certification scopes.

ISCC CORSIA

The following documents constitute the system basics of the ISCC CORSIA certification system applicable as of 01 January 2024. These versions of the documents have been submitted to ICAO in the framework of the recognition process of ISCC CORSIA under the ICAO CORSIA scheme. Please also note that the documents may be subject to change depending on the continuous development of CORSIA by ICAO. At the beginning of each system document, you will find a comprehensive summary of changes compared to the previous version.

ISCC CORSIA System Document 102: principles according to which the ISCC systems are governed globally. It specifies the goals and internal structure of ISCC, as well as the relationship between ISCC and its stakeholders.

ISCC CORSIA 103 – Requirements for Certification Bodies and Auditors

The document specifies the requirements for certification bodies to become recognised by ISCC and requirements and necessary qualifications of auditors conducting ISCC CORSIA audits.

Describing the ISCC CORSIA Certification System, the document outlines the certification criteria (sustainability requirements, traceability and life cycle emissions), relevant participants in the certification system and the registration and certification procedure.

The document provides the principles for the certification of raw materials and feedstocks qualifying as waste, residues and by-products, their supply chains and specific certification requirements that may differ from crop-based biomass.

The document explains the sustainability requirements that are valid for farms or plantations.

This document describes the requirements for traceability and chain of custody applicable to all elements of an ISCC CORSIA supply chain handling sustainable material.

This document lays down how to conduct audits under ISCC CORSIA, including adjusting audit intensity in accordance with the risk management process.

The intention of the document “Life Cycle Emissions” is to provide the methodology, rules and guidelines for calculating, reporting and verifying emissions reductions. The methodology described here is based on the ICAO Document “CORSIA Methodology for Calculating Actual Life Cycle Emissions Values” (2022). It further lays down the basic requirements for low LUC risk certification under ISCC CORSIA.

This document specifies requirements for the certification of groups, including the principles for sampling.
