Overview
- Mercedes and its customer teams McLaren, Williams and Alpine can race in Melbourne on the now‑homologated Petronas 2026 sustainable blend.
- The approval followed a late sign‑off after delays tied to verifying supplier certifications and supply‑chain traceability rather than fuel chemistry.
- The FIA tasked Zemo Partnership with auditing feedstocks, production routes and lifecycle greenhouse gas figures to meet the new rules.
- During pre‑season running in Barcelona and Bahrain, the FIA allowed chemically compliant but not yet fully certified fuels to keep testing on track.
- BP said it secured approval in the last couple of weeks after starting the process years earlier, underscoring how early preparation eased the transition.
