ISCC System Updates 


We have updated the template for ISCC PLUS sustainability declarations (SDs) to reflect the following changes based on the standalone ISCC PLUS System Documents:

• Alignment with the chain of custody methods
• Alignment with recent developments under the mass balance chain of custody method
• Provision for reflection of input characteristics
• Provision for extent of input compensation
• Provision for multi-site credit transfer applied upstream or by System User
• Annex for additional product information and add-on related information
• Updated material list

The updated template (v4.0) and the corresponding guidance document are available in the client section (login required). 

System Users are required to include the updated mandatory information by 1 January 2027.

We herewith introduce two new templates for sustainability declarations (SD).

The new SD template for the delivery of raw materials shall only be used by, and is valid for, the following entities:

• Individually certified Points of Origin, Farms/Plantations, and Forest Sourcing Areas
• Collecting Points
• First Gathering Points
• Points of Origin, Farms/Plantations, and Forest Sourcing Areas covered under Central Offices

The new SD template for the delivery of CO₂ shall be used by entities delivering atmospheric, post-industrial, and biogenic (bio and bio-circular) CO₂. Atmospheric and post‑industrial CO₂ do not fall under an existing raw material category under ISCC PLUS. With this new SD template, outgoing deliveries of CO₂ (involving atmospheric and post‑industrial CO₂) shall be declared accordingly.

If such CO₂ is further processed, please refer to Chapter 6.4.5 in ISCC PLUS System Document 203-2 ”Chain of Custody” for additional requirements.

System Users are required to include the updated mandatory information by 1 January 2027.

We are pleased to announce the launch of the ISCC PLUS add-on which is aligned with EN 15343. This add-on applies only to raw materials, intermediates, and final products derived from mechanical recycling activities and using either the chain of custody option physical segregation or controlled blending.

The relevant requirements of EN 15343 are included in the ISCC PLUS System Documents and in the ISCC PLUS Add-on Document “EN 15343”, which outlines the specific criteria and procedures covered by this add-on. Please note that the requirements are already integrated in the ISCC PLUS audit procedures and in the Audit Procedure System (APS).

The ISCC PLUS self-declaration for recycling according to EN 15343 (v1.0) is available in the document library (login required) and must be provided by Points of Origin to certified companies using this add-on. The updated ISCC PLUS sustainability declaration (v4.0) includes necessary information according to EN 15343, which must be forwarded along the supply chain.

Please note the following important information regarding accreditation:

• The ISCC PLUS EN 15343 add-on is not applicable in regions where national regulations mandate the Certification Body to be accredited in accordance with EN 15343, such as Spain. Under the current Spanish legal framework, the ISCC PLUS EN 15343 add-on cannot be used to demonstrate compliance with the Spanish Law 07/2022. We will keep stakeholders informed about any updates regarding the process of suitability for accreditation and the potential applicability of the add-on in additional markets.

For markets or countries where alignment with the EN 15343 standard is sufficient to demonstrate compliance, the ISCC PLUS EN 15343 add-on may be used.

For any questions or further information, please contact the ISCC PLUS team.

Materials certified under ISCC Canada CFR are now accepted under ISCC PLUS. This integration enables System Users to supply agricultural or forest biomass feedstocks certified under ISCC Canada CFR into ISCC PLUS-certified supply chains, maintaining full traceability and compliance with the ISCC PLUS scheme requirements.

The ISCC PLUS material list has been updated. The newly added and revised materials are marked in bold.

In addition, the following clarifications and updates have been introduced:

• The raw materials marked with an ‘*’ in the table 1 are classified as high-risk materials. For audits of Collecting Points, Central Offices, and individually certified Points of Origin, a high-risk level must be applied when these entities handle high-risk materials (please see ISCC PLUS System Document 204 “Risk Management”). The application of this requirement will become mandatory from 1 January 2027, based on the standalone ISCC PLUS System Documents.
• Clarification on handling high-risk materials from ISCC EU and ISCC CORSIA material lists.
• Clarification on prefixes used for ISCC EU material categories that are not applicable to ISCC PLUS materials. The application of this requirement will become mandatory from 1 January 2027 based on the standalone ISCC PLUS System Documents.

We are pleased to announce the release of a new version of the Audit Procedure System for ISCC Auditors and Certification Bodies (APS v6.0), which will be launched together with the updated audit procedures during the week of 23 – 27 February 2026.

APS 6.0 will become mandatory on 23 March 2026. 

Before this date, voluntary adoption is strongly encouraged to ensure a smooth transition to the new version. Audits starting after 23 March must be carried out in APS 6.0. Any audits starting after this deadline that are completed in APS 5.1 will not be accepted and must be recreated in APS 6.0.

Additional information on the update will be provided upon the release of APS 6.0.

For questions regarding the new APS update, please contact the APS Helpdesk at aps@iscc-system.org.

We have added a new billing information section to the registration form in the ISCC HUB as part of our continuous efforts to improve data quality and simplify administrative processes. Previously, billing details were reflected in the Main Audit Report.

The billing information section includes the following mandatory fields:

• Billing Contact Person
• Billing Address

Once a registration has been approved, an “Update Billing Information” button will be displayed, allowing System Users to modify the details in this section without additional CB approval. Any saved changes will take effect immediately. For step-by-step instructions, please refer to section 5.1.5 of the ISCC HUB Manual for System Users.

To facilitate this change, the billing information section has been pre-filled with the billing information currently available for each registration. We kindly ask System Users to review and confirm the accuracy of their billing information in the HUB latest by their next audit, to ensure correct invoicing and continued compliance.

For new registrations, Certification Bodies are required to verify during the registration data check and adjustment that the billing information section has been completed correctly. After this initial verification, the maintenance and accuracy of the billing information is the responsibility of the System User. Confirmation of the validity of the billing details will be required as part of each certification audit.

In accordance with ICAO CORSIA requirements, every sustainability certification scheme, including ISCC CORSIA, is required to submit an annual report to the International Civil Aviation Organization (ICAO). This report must contain information on the certified products handled by each System User under ISCC CORSIA during the previous calendar year.

To fulfil this reporting obligation, we will collect the necessary data from all System Users that held ISCC CORSIA or ISCC CORSIA PLUS certification at any point in 2025. The information submitted must be accurate, complete, and provided within the specified deadline.

In preparation for this process, we remind all System Users to ensure that their contact details in the ISCC HUB are fully accurate and up to date. We will rely on these contact details provided in the ISCC HUB when reaching out to System Users for data collection.

The ICAO CORSIA Positive List of materials classified as co-products, residues, wastes or by-products has been updated (Chapter 4.2, Table 1, ICAO CORSIA document “CORSIA Methodology for Calculating Actual Life Cycle Emissions Values”).

In addition, specifications for several raw materials have been introduced (see Sections 4.2.2, 4.2.3, 4.2.6, 4.2.7, 4.2.8, 4.2.9, 4.2.10, and 4.2.11 of the same document). New subcategories “Agricultural by-products”, “Forestry by-products”, and “Processing by-products” have been added, along with the allocation of existing feedstocks to these subcategories.

We have updated the corresponding provisions in the ISCC CORSIA Material List accordingly. The newly added and revised materials are marked in bold. New material entries with their specifications are now available in the ISCC HUB.

We have published the new ISCC PLUS GHG Add-on Document to explain the application of the voluntary GHG add-on under ISCC PLUS for the calculation and reporting of greenhouse gas (GHG) emission values along the supply chain. It sets out the methodology, rules, and guidelines for calculating and verifying GHG emissions and emission reduction. 

We recommend the application of this add-on for fuel products. The document outlines the GHG calculation methodologies for biofuels and Renewable Fuels of Non-biological Origin (RFNBOs). For any other products for which the GHG add-on has limited applicability, please refer to ISCC Carbon Footprint Certification (CFC).

Public Consultation

We welcome feedback from System Users, Certification Bodies and other interested stakeholders. The ISCC PLUS GHG Add-on Document (v1.0) is open to public consultation until 20 April 2026. Interested parties can download the document and submit their feedback on the ISCC website.

This is to clarify that “Soapstock acid oil contaminated with sulphur” is considered a waste/residue raw material as per the UK RTFO feedstock list. Therefore, upstream certification is not required. 

However, it must be ensured that the material qualifies as a waste/residue, i.e., that:

• the process is not conducted with the intention to sell a more valuable product, and 
• there was no intentional contamination (e.g., by using more acid than necessary). 

Additionally, the contamination has to make the material unsuitable for other uses (e.g., animal feed). Please note that the acceptance of fuel derived from this feedstock depends on the acceptance of the national authorities where the final fuel is sold.

The material name “Biomethanol” shall be used if 

• physically segregated biomaterial is processed, or 
• if mass-balanced biomethane via the gas grid is used in an SMR. 

When methanol is obtained from co-processing (e.g., end of life tyres), the wording “Co-processed oil to be used for replacement of methanol” shall be used. Mass balanced biomethane from the gas grid is not an eligible bio feedstock under co-processing.
