Request for input: Update to advice on the fourth emissions budget

Closes 19 Jul 2026

Biogenic methane

When the Commission presented its fourth emissions budget advice the 2050 target was a 24–47% reduction in methane relative to 2017 levels. Our advice was that a 38% reduction of biogenic methane by 2050 was technically and economically achievable based on available evidence.  

The revised 2050 biogenic methane target now requires a smaller reduction in emissions of 14–24% below 2017 levels. This change may limit how much we can expect biogenic methane emissions to reduce over the emissions budget periods. 

The responses we receive to this question will be used to inform the decision on what level of biogenic methane reduction in the fourth emissions budget period (2036-2040) appropriately reflects the 2050 target, for the purposes of our modelling. 

Where within the target range for biogenic methane should the fourth emissions budget aim to put the country on track for in 2050?
Please provide an explanation for your position.
