Request for input: Update to advice on the fourth emissions budget
Our proposed approach
As this is an update to existing advice, we are focusing on how changes to the Climate Change Response Act affect our previous analysis rather than undertaking a fresh analysis. However, we will consider any relevant important changes since we gave our advice in December 2024.
We intend to approach this in two parts:
-
Updating our existing analysis based on significant changes and methodological changes in the Greenhouse Gas Inventory that have occurred since December 2024, to assess whether our previously recommended emissions budget levels still reflect what is feasible.
-
Assessing whether our updated assessment of what is feasible is consistent with the ambition level set by the 2050 target, with a particular focus on the recent change to the biogenic methane component of the target.
We will not be revisiting other aspects of our advice, including rules for measuring progress towards emissions budgets and the 2050 target and limits to offshore mitigation.
Much of our approach is determined by the constraints of the Climate Change Response Act and timeframes but we are keen to understand people’s perspectives on how we approach our task.
