One idea we're keen to explore: a differentiated guaranteed strike price for fuels that achieve close to 100% carbon intensity reduction. This would incentivise 2nd generation fuels and e-fuels - the fuels that will be central to the SAF mandate post-2030. 4/5

That's why AEF responded to the UK Government's consultation on the revenue certainty mechanism within the SAF mandate. The detail here really matters for what gets built and funded. 3/5

A "solution" that drives deforestation isn't really a solution at all. The aviation industry needs to be honest about what counts as genuinely low-carbon fuel - not just fuel that ticks a box. 2/5

UK ‘green’ jet fuel imports linked to illegal Amazon deforestation A major supplier of ‘green’ airline fuel to the UK has sourced beef fat linked to illegal Amazon deforestation.

🧵 Getting sustainable aviation fuel (SAF) right isn't just about using any alternative fuel — it's about using the right ones. A new report from @unearthednews.bsky.social shows why this distinction matters more than ever. 1/5

A colossal white elephant: Government selects most disruptive and costly option for Heathrow expansion - Aviation Environment Federation On Tuesday 25th of November, the Government announced its selection of Heathrow Airport Limited’s (HAL) proposal as the basis for progressing plans for the third runway project. If approved, this …

Heathrow expansion means more planes, more flight paths and more noise. Over 2 million people could face increased aircraft noise if a 3rd runway is built and many communities are unaware their daily environment could be about to change forever.

Double counting risks and incomplete documentation in global accounting of emissions reductions from SAF - Aviation Environment Federation The environmental integrity of using SAF to reduce emissions from aviation is at risk if the current regulatory reporting system is not improved or properly implemented.

Feedstocks for sustainable aviation fuels (SAFs) are supposed to be carefully vetted. But while you should in theory be able to trace a feedstock through its lifecycle, the reality can be a lot murkier. Meeting the UK's SAF mandate involves convoluted supply chains and opaque certification. 3/4

The short answer: beef tallow - a waste product used to make jet fuel - is being sourced from farms linked to illegal deforestation in a Brazilian conservation area, as reported by UnEarthed. The longer answer involves global supply chain risks and life cycle analysis. 2/4

Heathrow already carries £17.6bn in debt, and expansion means stacking billions more risk onto an overstretched balance sheet.

Expansion isn’t “investment” — it’s a balance-sheet gamble with passengers footing the bill. #NoThirdRunway

Stop touristification! 🛑

Over tourism, not only kicks residents out of their homes, turning cities into tourist playgrounds, but also relies on air traffic and airport expansion.

Less tourism, less planes 👉 more homes, a better life!

Non-CO₂ effects of aviation (including contrails) - Aviation Environment Federation Aviation causes additional emissions and warming beyond the impact of CO₂ alone – known as non-CO₂. These emissions include sulphur, nitrogen oxides, particles including black carbon (soot) and water ...

Want to learn more about contrails and their climate warming effect? Take a look at this page, which outlines the non-CO₂ effects of aviation.

The study argues that, once uncertainty factors such as unpredictable meteorological changes are accounted for, 60% of flights with a warming contrail effect could be rerouted to avoid contrail formation. 2/3

COMMENTARY: The climate impact of contrails – why targeting a small share of flights could make a big difference The climate impact of persistent contrails from aircraft is receiving growing attention from policymakers, with the EU currently developing policies to integrate them into climate regulations. In a re...

Should all contrails be avoided?

A new study argues it’s less effective to avoid all contrail formation, and instead, action should be taken to target the percentage of flights that are expected to cause significant amounts of warming contrails. 1/3

Using plants and crops for fuel feedstocks is inefficient and risks indirect land-use change. Tweaking the SAF Mandate to allow more biomass feedstocks is a bad idea, for many reasons.
