Here are the climate-related sections of speeches by MPs during the Commons debate Sustainable Aviation Fuel Revenue Certainty Mechanism.
Heidi Alexander (Labour)
Sustainable aviation fuel is integral to reaching net zero aviation by 2050. It reduces greenhouse gas emissions by around 70% on average over the lifecycle of its production and use when replacing fossil kerosene. It is also an enabler of growth, and can provide good, skilled jobs across the UK.
The SAF mandate is the UK’s key policy mechanism to secure demand for SAF. It delivers GHG emission savings by encouraging the use of SAF within the aviation industry. It does this by setting a legal obligation on fuel suppliers in the UK to supply an increasing proportion of SAF over time. Suppliers receive certificates for the SAF they supply. Certificates are issued in proportion to the level of GHG emission reductions that the fuel delivers—that is, the greater the savings, the greater the number of certificates they receive. The SAF mandate started at 2% of total UK jet fuel demand in 2025 and increases linearly to 10% in 2030 and then to 22% in 2040. It could deliver up to 6.3 million tonnes of carbon savings per year by 2040.
