Next steps for aviation decarbonisation in the UK

This conference will examine next steps for aviation decarbonisation in the UK. Areas for discussion include the way forward for increasing the use of sustainable aviation fuel, alongside putting in place conditions that can foster investment, and support delivery and supply chain development. The role of newer technologies and carbon removal pathways within the UK’s wider approach to aviation decarbonisation will also be considered.


It will bring together stakeholders and policymakers to discuss key issues for implementation and delivery, in the context of the UK Sustainable Aviation Fuel Mandate, the Sustainable Aviation Fuel Act 2026, and recent work of the Jet Zero Taskforce on sustainable aviation fuel, hydrogen, and greenhouse gas removals. Delegates will assess implications of the Sustainable Aviation Fuel Act 2026 and the Revenue Certainty Mechanism for domestic production, investor confidence, supply chain development, and airline costs. Progress towards current SAF Mandate obligations will be examined, with including the balance between domestic capacity and imports, alongside considerations emerging from the Department for Transport’s call for evidence on crop-derived sustainable aviation fuel - including sustainability criteria, feedstock availability, and the role such fuels might play within the wider SAF mix.


Regulation, market frameworks & transparency
Further discussion will look at the wider regulatory and commercial framework for decarbonisation. Attendees will consider developments arising from the UK Emissions Trading Scheme Authority’s consultation on the treatment of sustainable aviation fuel, alongside implications of the Civil Aviation Authority’s new guidance on publishing emissions information. Practical steps will be assessed. looking at what may be needed to support transparency, affordability, competitiveness, and long-term confidence across airlines, airports, fuel producers, investors, and related supply chains.


Technology pathways, infrastructure & planning for deployment
The agenda will also assess how near-term emissions reduction measures and longer-term technology choices can best fit together. Areas for discussion include operational efficiencies across airlines and airports, and alignment between decarbonisation objectives and airport expansion and planning decisions, in the context of the ongoing review of the Airports National Policy Statement. Attendees will also consider implications of the Jet Zero Taskforce’s latest work on hydrogen-powered aircraft and greenhouse gas removals. We expect discussion around technical readiness, infrastructure requirements, commercial viability, and the likely pace of deployment.


Overview of areas for discussion


  • policy:
    • implementation of the Sustainable Aviation Fuel Act 2026 and UK SAF Mandate
    • scaling up domestic production capacity - implications of the Revenue Certainty Mechanism for investment decisions
  • mandate delivery: assessing progress towards the 2% SAF obligation and pathway to 2030 targets - mix of domestic production and imported fuels - implications for airline compliance costs
  • investment: financing models for new SAF production facilities - allocation and funding structure of the Revenue Certainty Mechanism - implications for investor certainty and project viability
  • feedstock: availability of sustainable supply for SAF production - implications of crop-derived fuels consultation for land use and lifecycle emissions - sustainability criteria priorities
  • competitiveness and costs:
    • implications of SAF price differentials with conventional jet fuel - potential impacts on ticket prices and route economics - concerns around international competitive balance
  • emissions regulation: UK ETS Authority consultation on treatment of SAF - interaction with carbon pricing and airline compliance costs - relationship with international schemes such as CORSIA
  • capabilities: workforce and supply chain readiness for scaling SAF production and new fuel infrastructure - collaboration between airlines, airports, fuel producers and energy sector partners
  • implementation: near-term emissions reductions through airspace modernisation and operational improvements - improving flight efficiency and aircraft performance across fleets and airports
  • infrastructure planning:
    • alignment between aviation decarbonisation goals and airport expansion proposals
    • implications of the review of the Airports National Policy Statement for planning and environmental assessment
  • long-term innovation:
    • prospects for hydrogen-powered aircraft and emerging propulsion technologies - infrastructure and certification - timelines for commercial deployment and carbon removals integration
