Recently this year, the International Sustainability & Carbon Certification (ISCC) Association announced that it had added new members to its multi-stakeholder initiative, including Petrobras, Infinium, Petroineos Trading Limited, and Montana Renewables, LLC. As of January 19, there are 341 ISCC Association Members on the official member list.

Their entry into the association could reflect a consensus among companies from different areas (like energy, fuel, and other industries) that credible certification is becoming an essential tool, not only for meeting regulatory expectations, but also, according to the ISCC 2025 impact report, for supply chain transparency and for organizations to get closer to sustainability and climate objectives.

​According to the ISCC, its association functions as the governance body of the ISCC System, a widely recognized certification system for sustainable biomass, renewable fuels, circular materials, and low-carbon products. Through its multi-stakeholder structure, the Association brings together companies, NGOs, research institutes, and public-sector representatives to oversee the strategic development of ISCC certification standards that would help build sustainable supply chains.

The newest additions to the association

Among the new members, two of them are U.S.-based companies. Infinium is a global leader in electrofuel production, such as sustainable aviation fuel, designed to reduce greenhouse gas emissions by up to 90% across the aviation, marine, and trucking sectors, according to the World Economic Forum. And there’s also Montana Renewables, LLC.

The last-mentioned has established itself as a leading North American producer of SAF and renewable diesel, and also holds voluntary certifications, including ISCC EU and ISCC CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation).

Petroineos Trading Limited, a major trading company in the global energy markets, has also joined the ISCC Association, just like Petrobras, a Brazilian state-controlled oil, gas, and energy company. As above, it has obtained multiple certifications, including ISCC CORSIA and ISCC EU, which consolidate Petrobras’ focus on sustainable biofuels and SAF.

How organizations can become ISCC Association members

As stated on the ISCC website, to become a member, an organization must follow the application process.

First of all, the ISCC states that the applicant must be a legal entity, a partnership, or another entity with legal capacity. If everything is in order, the organization interested in becoming a member of the association can proceed to the first step: complete and submit the application form available on the ISCC website.

This form collects basic organizational information (such as name, address, sectors, and regions of operation) and includes a section on what is the motivation to join and also on how the organization contributes to or supports ISCC’s sustainability goals.

After submission, the ISCC Association Board reviews the application and decides whether to accept or reject the applicant. The decision is based, according to the ISCC System Support Centre, on the organization’s potential contribution to the Association’s objectives and tasks, as stipulated in the ISCC Statutes.

After the decision is made, it is communicated to the applicant. And last but not least, upon joining the Association, ISCC states that member entities must pay membership fees in accordance with the relevant category outlined on its website. Fees are due per calendar year.

In short, the number of members of the International Sustainability & Carbon Certification Association appears to be increasing, indicating companies’ interest and trust in certification and sustainable supply chains. Likewise, any organization interested in joining the ISCC Association can follow the steps outlined above.
