ISCC System Updates 


A new Proof of Compliance (PoC) template (v1.0) tailored for RFNBOs and their upgraded or liquefied forms is now available in the document library on the ISCC website (login required).  

The new template for RFNBOs integrates key elements from the existing PoC frameworks. 

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

We would like to highlight the addition of “Pyrolysis oil” and “RCF Pyrolysis oil”. “Pyrolysis oil” shall be used for oil produced from the pyrolysis of biogenic material whereas “RCF Pyrolysis oil” shall be used for oil produced from the pyrolysis of fossil RCF feedstocks. Oil produced from the pyrolysis of end-of-life tyres shall no longer be certified as “Crude oil” or “RCF crude oil”. 

We hereby clarify the provisions stated in Chapter 6, “Information provided upon request” of ISCC EU System Document 102 “Governance” (v4.2). (LINK) 

Under this provision, we provide information in response to legitimate requests from competent authorities, including the European Commission, the competent authorities of EU Member States, and other relevant national authorities.  

Legitimate requests include, but are not limited to, the following: 

• Requests where ISCC has a legal, administrative, judicial or contractual obligation to disclose the requested information. 

• Requests where the disclosure of information is in the interest of ISCC to safeguard the integrity of the ISCC certification system or to detect major or critical non-conformities and where the receiving authority is bound by confidentiality obligations which ensure that any confidential information received is treated as such and not disclosed, unless there is a legal obligation to disclose it, and the recipient of the information is bound to confidentiality obligations.  

The ISCC PLUS sustainability declaration templates are now available in PDF format in addition to the existing Excel format. They can be accessed in the document library on the ISCC website (login required). 

The use of the sustainability declaration templates is voluntary, as we do not prescribe a specific format or layout for sustainability declarations. Provided that all required sustainability information is included, companies are free to design their own templates or incorporate the information into existing delivery documents (e.g., a bill of lading).   

Note: the PDF template is only compatible with Adobe Acrobat.

We would like to inform all stakeholders that ICAO has approved the updated set of ISCC CORSIA System Documents. All system documents are available in the document library of the ISCC website.

The revised documentation includes the following key changes and additions: 

• Requirements for the certification of cellulosic feedstocks bearing a negative default ILUC value (Chapter 3.1, ISCC CORSIA System Document 202 “Sustainability Requirements”); 

• Requirements on electricity sourcing (Chapter 5, ISCC CORSIA System Document 202 “Sustainability Requirements”); 

• Requirements on Soil Carbon Accumulation (SCA) (Chapter 8, ISCC CORSIA System Document 205 “Life Cycle Emissions”); 

• Requirements on Carbon Capture and Storage (CCS), including seismic and vibrational effects from CCS (Chapter 7, ISCC CORSIA System Document 205 “Life Cycle Emissions” and Chapter 12, ISCC CORSIA System Document 202 “Sustainability Requirements”); 

• Extension of low LUC risk practices up to 2035; 

• New requirements on LCA calculation for waste and residues of fossil origin (Chapter 6.5, ISCC CORSIA System Document 205 “Sustainability Requirements”); 

• Integration of the ISCC CORSIA methodology for calculating actual GHG emissions into ISCC CORSIA System Document 205 (including extension of Life Cycle Stages), replacing the previous reference to ISCC EU System Document 205; 

• Comprehensive alignment of the ISCC CORSIA documentation with the terminology and structure of the current ISCC EU and ISCC PLUS systems, providing greater consistency and a more streamlined user experience. 

Please note that certifications related to Soil Carbon Accumulation (SCA) and Carbon Capture and Storage (CCS) are currently on hold while ISCC pilots and validates the new requirements. Economic operators interested in obtaining certification for CCS or SCA under ISCC CORSIA are encouraged to contact us at aviation@iscc-system.org. 

As agreed with ICAO, a transition period of three (3) months will be granted until 22 October 2026. During this period, application of the new requirements will be voluntary. From 23 October 2026 onwards, compliance with the new requirements will become mandatory. 

The audit procedures will be available in the document library of the ISCC website shortly (login required). The revised audit requirements will also be implemented in a new version of APS, which will be released soon. 

The following templates have been updated and are now available in the document library of the ISCC website (login required): 

• Template for ISCC CORSIA Proof of Sustainability (PoS), v2.2 

• Template for ISCC CORSIA Sustainability Declaration, v2.2 

The use of such templates remains voluntary, as we do not prescribe a specific format or layout for sustainability declarations and PoS. Provided that all required sustainability information is included, companies are free to utilise their own templates or incorporate the information into existing delivery documents (e.g., a bill of lading). 

Additionally, a self-declaration for electricity producers is now available in the document library of the ISCC website (login required).

Following discussions with ICAO, the ISCC CORSIA PLUS certification system (applicable only to Farms/Plantations, First Gathering Points, and Central Offices of Farm/Plantation scopes) will be discontinued as of 23 October 2026.  

This decision reflects the fact that, following the introduction of the extended ICAO Sustainability Criteria on 1 January 2024, differences between ISCC CORSIA and ISCC CORSIA PLUS have become negligible. Certificates issued under ISCC CORSIA PLUS will remain valid until their respective expiration dates. Upon expiry, economic operators will only be eligible for re-certification under the ISCC CORSIA certification system. 

“Empty Palm Fruit Bunches” are categorised as “Processing Residues” under ICAO CORSIA. Within CORSIA, wastes, residues, and by‑products are assigned zero emissions at feedstock generation stage. However, if preprocessing is required to adjust the quality of these materials for subsequent processing steps, all associated emissions must be included in the greenhouse gas (GHG) life‑cycle analysis (LCA). For “Empty Palm Fruit Bunches”, this requirement means that any emissions generated during the extraction of the oil from the raw material must be included in the GHG LCA. 

Under ISCC CORSIA, the same system boundary used for default LCA values must be used for any actual GHG LCA value calculated under CORSIA. The system boundary for each pathway is defined in the CORSIA Supporting Document “CORSIA Eligible Fuels – Life Cycle Assessment Methodology“

We have published a new ISCC Carbon Footprint Certification (CFC) System Document on "Conventional Processing". This document is complementing the existing ISCC CFC System Document (v1.4), which remains fully valid. The scope of this module currently includes natural gas as a feedstock, with the possibility of expanding coverage to additional conventional feedstocks in the future. 

Public Consultation 

We welcome feedback from System Users, Certification Bodies and other interested stakeholders. The ISCC CFC System Document – Conventional Processing (v1.0) is open to public consultation until 11 September 2026. Interested parties can download the document and submit their feedback on the ISCC website. 

The following self-declaration translations, applicable to both ISCC EU and ISCC PLUS, have been updated: 

• Farm/Plantation (EU) 

• Farm/Plantation (Non-EU) 

• Independent Smallholders 

• Collection of Wild-Growing Shea 

• Collection of Wild-growing Croton 

• Waste and Residues 

In addition, the following self-declaration translations, applicable to ISCC EU only, have been updated: 

• Used Cooking Oil (UCO) 

• Food Waste 

The updated self-declaration translations are available in the document library of the ISCC website (login required). 

This update improves the existing legal provision regarding the validity of the translated versions, which clarifies that, in the event of any discrepancy between the signed translation and the original English version available on the ISCC website at the time of signing, the English version shall prevail. 

The updated translated self-declarations are valid as of 1 July 2026, and their use will become mandatory on 1 January 2027.  

Note: System Users who only use the English version do not need to take any further action. 

The following sentences are hereby deleted from ISCC EU System Document 102 “Governance” (v4.2) and ISCC PLUS System Document 102 “Governance” (v1.1): 

• “Upon receipt of the Integrity Assessment Report, the System User must provide ISCC with a signed version of the report”; 

• “Upon receipt of the Integrity Assessment Report, the CB must provide ISCC with a signed version of the report”; 

• “If applicable, the report may contain the results of a detailed remote sensing analysis in order to verify ISCC Principle 1 (if applicable for agricultural or forest biomass), which will be included as an attachment.”
