Enabling Credible and Transparent Claims

Current supply chain certification systems cover sustainability, GHG emissions reductions, and traceability of Sustainable Aviation Fuel (SAF) from feedstock production to airport delivery. Until recently, there have been limited systems available to secure traceability and credibility of claims once SAF has been delivered to the airport.

This presents a challenge for organisations seeking to reduce their emissions footprint from air travel and transportation. To close this gap, we have developed the ISCC Credit Transfer System. Through integration with the ISCC Registry, a secure online database, the transfer of sustainability claims for SAF throughout the downstream value chain becomes possible. This solution enables SAF suppliers, aircraft operators, logistics providers, and end-customers to confidently track and allocate sustainability benefits associated with SAF use, supporting their voluntary climate disclosures.

Why does SAF matter on the pathway to net-zero?

One of the greatest challenges of our time is the fight against climate change. The urgent need to lower greenhouse gas emissions has also been recognised by the International Civil Aviation Organization (ICAO) and the aviation industry. ICAO Member States have set ambitious targets to mitigate greenhouse gas emissions from air transportation, including a collective long-term global aspirational goal (LTAG) of net-zero carbon emissions by 2050. With aviation generally considered a ‘hard-to-abate’ sector, widespread adoption of sustainable aviation fuels (SAF) is recognised as a key lever to achieving ambitious emission reduction goals.

SAF, a liquid fuel used in commercial aviation, is produced from renewable sources such as biomass, waste oils and fats, or green hydrogen, and reduces CO2 by up to 80%. The chemical and physical characteristics of SAF are nearly identical to those of conventional jet fuel, and they can be safely mixed with the latter to varying degrees, using the same supply infrastructure, and do not require the adaptation of aircraft or engines. For SAF to be deemed ‘sustainable’ it must meet a range of sustainability criteria, including a reduction in GHG emissions and ensuring feedstocks for production are not cultivated on high carbon stock lands.

To accelerate the aviation sector’s transition towards net-zero, a rapid ramp-up of SAF deployment is needed. International agreements such as the International Civil Aviation Organization’s (ICAO) CORSIA, and regional SAF policies such as the EU’s ReFuelEU Aviation Regulation will play a major role, in addition to voluntary SAF purchases beyond SAF emissions reduction trajectories already mandated by governmental policies.

How Does the ISCC Credit Transfer System Work?

Register Credits in the ISCC Registry

The SAF supplier registers SAF credits in the ISCC Registry, corresponding to the quantity of SAF delivered. Each metric ton of SAF creates both a Scope 1 and Scope 3 credit, in line with GHG accounting principles defined by the GHG Protocol.

Transfer Credits in the ISCC Registry

The SAF supplier transfers SAF credits in the ISCC Registry to organisations in its downstream value chain, including aircraft operators, logistics providers and end-customers.

Retire Credits in the ISCC Registry

Organisations retire credits available in their account. The ISCC Registry automatically issues a retirement declaration.

Claim SAF Credits

The retirement declaration includes information for the organisation to claim the sustainability characteristics associated with the retired credits towards their voluntary climate disclosures.

How to Get Involved:

Is the ISCC Credit Transfer System the Right Fit for You?

If you are a SAF supplier*, aircraft operator, logistics provider or end-customer looking to credibly reduce GHG emissions from air travel or transport, then yes! Make sure to establish commercial business relationship with partner organisations, outside the ISCC registry.

*SAF suppliers must hold valid trader certification in order to register credits and participate in the ISCC Credit Transfer System.

Trader certification can be achieved to any of the following certification schemes

  • A sustainability certification scheme (SCS) recognised by ICAO under CORSIA, including ISCC CORSIA
  • A voluntary scheme (VS) recognised by the European Commission under the revised Renewable Energy Directive (RED II), including ISCC EU
  • RSB Global

What ISCC Stakeholders Say:

“Sustainable aviation fuel is a key lever to reduce aviation emissions but to fully leverage its potential and accelerate SAF adoption in the voluntary market, it is critical for airlines, freight forwarders and shippers, and corporate end-customers to be able to credibly report their SAF use and related emission reductions. The ISCC Credit Transfer System provides additional credibility and transparency and can play a crucial role in enabling trust and confidence in SAF as an easy and credible solution to reduce emissions.”

With the globally increasing interest for Sustainable Aviation Fuel (SAF) and in-sector decarbonization, the ISCC credit transfer system enables a reliable chain of custody system beyond the boundaries of conventional mass balancing and the physical delivery of SAF. This is a significant step in making SAF accessible for organizations without physical supply access and also in allowing credible sustainability claims based on SAF, enabling commitments beyond regulations.” 

“Our DHL GoGreen Plus services use CO2-insetting and SAF to enable our customers to reduce the CO2e emissions associated with their shipments. We are keen to promote confidence in our customers who claim their CO2 reductions resulting from investments in low-emission transport services and SAF. The ISCC registry’s end-to-end tracking ensures that emission reductions are transferred reliably, transparently, and safely along the value chain. Its rigorous methodology is essential for reaching Science Based Targets initiative (SBTi) goals within the aviation sector and for airline customers.”

System Document “ISCC Credit Transfer System”

The System Document explains the background and motivation for establishing the system, lays out its guiding principles, and details the general functioning of the system, including the handling of credits within the ISCC Registry (i.e., registration, transfer, and retirement of credits). Furthermore, it includes requirements for auditing and verification. Lastly, it features provisions and recommendations on how GHG emissions reductions from SAF credits retired through the ISCC Registry should be accounted for and claimed in companies’ GHG inventories.
