Sustainable Aviation Fuel (SAF)

Reduce emissions from business travels and transportation

Aside from travelling less, SAF is currently the only recognised way to reduce the climate footprint of air travel

Sustainable Aviation Fuel (SAF) is a fossil-free aviation fuel made from renewable or waste-based feedstocks, such as used cooking oil, agricultural residues or carbon captured from the air. When SAF replaces conventional jet fuel, it can reduce greenhouse gas emissions by up to 80% over the fuel’s life cycle — without requiring new aircraft engines or changes to existing infrastructure. It is one of the most promising tools for reducing emissions from air travel and is already being used today.

Reduce Scope 3 with SAF

Air travel – particularly business travel – often represents a significant share of a company’s Scope 3 emissions. By investing in SAF, organisations can:

  • Directly reduce their flight-related emissions

  • Meet increasing CSRD requirements and align with Science Based Targets

  • Demonstrate concrete climate action to customers, employees, investors and others

By using SAF, the organisation not only takes responsibility for its own emissions but also helps scale the production of sustainable aviation fuel – which is essential for enabling the aviation industry to transition and meet future requirements.

Acknowledged by the Science Based Targets initiative

Several standards have acknowledged SAFc as a valid method to reduce emissions, including the GHG Protocol, the World Economic Forum and the Science Based Targets initiative (SBTi). SAF certificates (SAFc) are designed to align with the SBTi’s interim guidance and the GHG Protocol for accounting of Scope 3 emissions from business travel. They follow the WEF/RMI accounting framework for SAFc, SABA’s criteria, and CORSIA’s lifecycle methodologies, which the SBTi refers to as temporary best practice until a final standard for SAF accounting has been established.

SBTi has acklowedged the use of SAFc for Scope 3 reductions within the following categories:

  • Business travel (6)

  • Upstream transportation and distribution (4)

Companies such as Microsoft, Google, Boston Consulting Group and Deloitte are already using SAFc to reduce their aviation-related emissions.

Please note that the SBTi’s final guidance for SAFc is expected in 2026; our solution is based on recognised interim standards that ensure high integrity. Learn more in the Evidence Synthesis Report (mars 2025) for EAC-fuel.

Frequently asked questions

  • SAFc are certificates linked to the climate benefit of Sustainable Aviation Fuel, accounted for separately (“book-and-claim”) from the physical fuel itself.
  • Organisations can purchase SAFc to reduce their Scope 3 emissions from, for example, business travel and transportation, even if no physical SAF has been used in their own or their employees’ flights.
  • The climate benefit is calculated relative to conventional jet fuel on a life-cycle (“well-to-wake”) basis – and the emissions difference represents the amount of CO2e that can be deducted from the organisation’s reported Scope 3 emissions.
  • The reduction is accounted for as an emissions decrease in Scope 3 category 6 (business travel) or category 4 (upstream freight).
  • It is reported using the “dual reporting” approach recommended by WEF/SABA: both gross Scope 3 emissions and net emissions after the SAFc deduction are shown in the climate disclosures.
  • Distance- or fuel-based calculation methods, as outlined in the GHG Protocol guidance, are primarily used.
  • SBTi recognises SAFc as a valid method for reducing Scope 3 emissions linked to air travel and transportation.
  • Several global standards acknowledge and integrate SAFc, including the Science Based Targets initiative (SBTi), the GHG Protocol, ICAO CORSIA, the Roundtable for Sustainable Biomaterials (RSB), the Sustainable Aviation Buyers Alliance (SABA) and the World Economic Forum (WEF).
  • SAFc are physical value-chain insets that address Scope 3 emissions from business aviation in line with the SBTi’s current interim recommendations. They meet requirements for lifecycle analysis (well-to-wake), sustainability certification (ISCC/RSB) and transparent accounting, following the interim methodologies from WEF/RMI and SABA – with full transparency of the methodology until the SBTi releases its complete SAF standard
