Industry perspectives on version 2.0 of SBTi’s Corporate Net-Zero Standard FIGURE 10 Source: World Economic Forum survey of 18 First Movers Coalition members and partners active in the transport sector, December 2025.0 2 4 6 8 10 12 14 16 18Do you feel the r evised SBT i Corporate Net-Zer o Standar d is moving in a positive dir ection for your sector? Do you for esee any obstacles or challenges in applying the new SBT i requir ements to your operations or value chain?Yes Unsur e No No Unsur e Yes Respondents noted that the new SBTi requirements are becoming increasingly complex and difficult to operationalize, with limited criteria set out at this stage that would clarify the circumstances under which SAF certificates could be claimed. These issues are expected to be addressed by an update to the Greenhouse Gas Protocol’s Land Sector and Removals Guidance, planned for the first quarter of 2026. Even so, the uncertainties surrounding SBTi’s standards, including their timing and implications for Scopes 1, 2 and 3 accounting, are likely to continue to influence corporates’ decision-making processes well into 2026. On the positive side, some executives have highlighted that the current SBTi guidelines remain in place until further notice and these do recognise book-and-claim. As book-and-claim schemes attempt to take off in 2026, aviation executives interviewed for this report emphasised the need to navigate increasingly complex interactions between mandatory and voluntary markets, particularly in markets that are expected to operationalize new policies, such as Singapore, and markets where mandates are already in place, like the EU. To reduce the risk that fuels could be accounted for under multiple book- and-claim systems, and to boost credibility, industry stakeholders have highlighted that more work is needed to foster interoperable and transparent book-and-claim platforms as a priority. However, opinions are divided on where the responsibility for coordinated action should sit. Additional challenges preventing the growth of book-and-claim include complex corporate governance and SAF procurement processes for corporates, which, unlike airlines, are not used to procuring fuel; these challenges are exacerbated by unclear future SAF market prices that affect negotiations and pricing structures. While these hurdles are hampering the uptake of SAF by new players, more experienced corporates that have purchased SAF in the past are also facing more complex, sophisticated demands, such as the need to account for SAF against specific flights or airlines. Navigating these difficult processes requires further guidance and peer learning from companies that have already taken up SAF offtakes. To this end, in May 2025, the World Economic Forum in collaboration with GenZero launched Green Fuel Forward in Singapore. This initiative aims to widen the pool of businesses interested in SAF certificates, by building awareness of the avenues available to purchase SAF, and their sustainability, procurement, accounting and reporting implications. Several players, such as Amex GBT, Shell, OMV, LanzaJet, Sumitomo Mitsui Banking Corporation (SMBC), Temasek, BOC Aviation, Microsoft, SkyNRG and multiple airlines active in Asia-Pacific are involved.
