ISCC System Updates 


The ISCC EU RFNBOs CO₂ Self-Declaration has been updated to include GHG emissions related to the CO₂ capture effort. 

This clarification concerns the treatment of end-of-life tires within ISCC EU supply chains. If end-of-life tires are cut or shredded as part of waste treatment at the Point of Origin (e.g. by a collector operating under the supervision of a national scheme), and the material can be forwarded with a waste code, it qualifies as a waste or residue under ISCC EU. In such cases, the material shall be declared as either “Biogenic fraction of end-of-life tires” or “Fossil fraction of end-of-life tires”.

Crude oil that undergoes processing or partial refining at an oil mill but is not fully refined at that mill or at any intermediate processing unit, shall receive the new material name “Semi refined oil”.

This classification applies, e.g., when processes such as degumming or neutralisation are performed to stabilise the oil, but the specifications of a fully refined oil have not yet been met.

The economic operator performing this partial refining must be certified under the scope “Refinery”. Additionally, if the economic operator supplies waste or residue materials generated during the refining process, they must be individually certified as a Point of Origin (PoO) to supply waste or residue materials under ISCC.

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

Certification of RCF supply chains is now possible under ISCC EU. Eligible materials are listed on the ISCC EU material list and currently include:

• Fossil fraction of end-of-life-tires
• Fossil municipal solid waste
• Waste gases
• Waste engine oils

The ISCC EU material list has also been expanded by a guidance tree to assess the eligibility of a feedstock in the specific set-up. The addition of further RCF feedstock materials will be based on a case-by-case assessment following requests for addition.

ISCC Auditors of RCF supply chains must hold the ISCC EU RFNBOs/RCFs Training qualification (on top of the ISCC EU Training).

The following documents are available on the ISCC website (login required):

• Audit Procedure: Recycled Carbon Fuels under ISCC
• Self-declaration: Point of Origin for Recycled Carbon Fuels (RCFs)
• ISCC EU PoS for Recycled Carbon Fuels (RCFs)

From 1 May 2026, it will be mandatory for ISCC Auditors certifying co-processing setups to have completed the ISCC EU Co-Processing Training and successfully passed the ISCC Auditor Online Test.

Two ISCC EU Co-processing training courses have already been held, and the next training course will take place on 8 October 2026. Registration is now open.

The mandatory ISCC CORSIA reporting deadline of 15 April 2026 has passed. We are currently finalising our report to ICAO and require all outstanding data to be submitted to us by CORSIA (PLUS) certified entities handling final CORSIA fuels in calendar year 2025 as soon as possible. 

Due to outstanding submissions, the reporting period has been extended until 30 April 2026 (end of business).

All System Users holding ISCC CORSIA (PLUS) certification at any point in 2025 are required to submit a report. System Users who handled CORSIA-eligible fuels must disclose information on such. For organisations with multiple registrations, a separate submission is required for each registration. 

Please note that the identified primary contact person (as listed in the ISCC HUB) for each certified entity is responsible for submitting the data on behalf of their organisation and has received direct emails and follow-ups with information. 

Submission of this information may serve as a prerequisite for ISCC CORSIA (PLUS) recertification. For questions, contact aviation@iscc-system.org and reference “REPORTING 2025 – ISCC REG‑XXXX” in the subject line. 

If your organisation has already submitted the CORSIA report, no further action is required.

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.
