ISCC System Updates 


To improve transparency and consistency across ISCC certification schemes, we are requiring the mandatory specification of the applicable chain of custody option in the certificate templates across all certification schemes.

We have already published updated certificate templates for ISCC EU and ISCC CORSIA in the CB client section of the ISCC website (login required). These templates include a dedicated field where Certification Bodies (CBs) must indicate the applicable chain of custody option verified during the audit (“Mass Balance” or “Physical Segregation”). This field is not applicable to System Users that do not physically handle certified material (“Traders without storage”).

The updated template shall be used for ISCC EU and ISCC CORSIA certificates issued from 1 September 2026 onwards. Certificates issued prior to this date will remain valid until their respective expiry dates. For those certificates, information on the System User’s chain of custody option remains available in the respective Summary Audit Reports accessible in the public ISCC certificate database.

When issuing new certificates, CBs must use the latest applicable certificate templates and follow the corresponding guidance documents for the use of the templates.

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

We have published a new ISCC PLUS GHG Add-on Document (v1.1) which provides guidance on the voluntary GHG add-on under ISCC PLUS for reporting greenhouse gas (GHG) emissions values along the supply chain. The document sets out the methodology, rules and guidelines for calculating and verifying GHG emissions and emissions reductions across the entire supply chain. 

Public Consultation

We welcome feedback from System Users, Certification Bodies and other interested stakeholders. The ISCC PLUS GHG Add-on Document (v1.1) is open for public consultation until 10 September 2026. Interested parties can download the document and submit their feedback on the ISCC website.

We have published a new ISCC PLUS Guidance Document for Steel Scrap (v1.0). It provides information for System Users involved in handling steel scrap and materials processed from steel scrap, as well as for Certification Bodies responsible for auditing and verifying the respective supply chain elements.

Public Consultation

We welcome feedback from System Users, Certification Bodies and other interested stakeholders. The ISCC PLUS Guidance Document for Steel Scrap” (v1.0) is open for public consultation until 22 September 2026. Interested parties can download the document and submit their feedback on the ISCC website.

When applying the tonne-km methodology, System Users shall consider the transport exhaust emissions, Ex, in [kg CO2eq (tonne km)-1].

When using the values from the Commission Implementing Regulation (EU) 2022/996, System Users shall calculate the exhaust emissions in accordance with the following equation where:

Ex = transport exhaust gas emissions [kg CO2eq (tonne km)-1],

CH4 = transport exhaust methane emissions [g CH4 (tonne km)-1],

N2O = transport exhaust nitrous oxide emissions [g N2O (tonne km)-1].

When calculating GHG transport emissions using the tonne-km methodology for material sourced from multiple points, System Users shall apply one of the following approaches:

1. the longest-distance approach specified in a); or

2. the weighted-average distance approach specified in b); or

3. individual distances and calculations for each sourcing contact.

System Users shall apply the selected approach consistently throughout the calculation.

a) Longest-distance approach

When applying the longest-distance approach, System Users shall use the longest transport distance among all sourcing contacts supplying the material.

b) Weighted-average distance approach

When applying the weighted-average distance approach, System Users shall calculate the weighted-average distance using the following equation:

Dw = weighted average distance [km],

m = mass of point of origin n [tonne],

D = transport distance from point of origin n [km],

n = number of sourcing contacts.

System Users using the weighted-average distance approach shall ensure that all supplies included in the calculation have the same transport mode, transport efficiency, fuel emission factor, and moisture content.

Separate transport emission calculations shall be performed for supplies that differ in transport mode or moisture content.

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

We would like to highlight that the raw material “Industry Food Waste Oil” will be removed from the ISCC EU material list. From 1 October 2026, this raw material can no longer be used for the initial certification and recertification of Points of Origin, Collecting Points, and Central Offices for waste and residues.

Please note that all certificates that include “Industry Food Waste Oil” and were issued before 1 October 2026 may remain unchanged until their expiration. Certification Bodies are therefore not required to remove “Industry Food Waste Oil” from the certificate material annex during the certificate's validity period.

Additionally, Sustainability Declarations (SDs) and Proofs of Sustainability (PoS) must continue to align with the raw materials listed in the corresponding certificate material annex. Therefore, for valid certificates issued before 1 October 2026, the raw material designation “Industry Food Waste Oil” may continue to be used in SDs and PoSs throughout the certificate's validity period.

Following the removal of “Industry Food Waste Oil” from the ISCC EU material list, System Users currently certified under this material category may, where applicable, transition to the material entry “Food Waste” upon recertification. The material entry “Food Waste” covers food that is out of date or out of specification. The use of the material name “Food Waste” is only permitted where the material complies with the definitions and requirements specified in the ISCC EU material list and the ISCC Guidance Document on Waste and Residues from Food and Food Processing.

Lastly, we would like to clarify the requirements for "Aflatoxin Contaminated Corn". Suppliers intending to use this material towards compliance with the UK RTFO must be able to demonstrate compliance with relevant requirements as listed on the UK Department for Transport (DfT) website.

We have published a new Mass Balance Template specifically designed for Collecting Points. It is available in the document library on the ISCC website (login required). 

The template provides practical support for implementing the ISCC EU mass balance requirements in a structured and transparent way. It supports System Users in documenting the sustainability characteristics required for quantity bookkeeping and facilitates the documentation required for each mass balance period.

The use of the template is voluntary. Provided that all applicable ISCC requirements are fulfilled and approved by the ISCC Auditor, System Users may adapt it to their individual needs or continue to use their own systems.

Date: 5 October 2026, 14:00 - 15:00 (CEST, UTC +2)

We offer a regular webinar series to keep our System Users, ISCC Auditors and other stakeholders informed about all recent changes and developments.

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)
