This is supplementary analysis for the CCC’s A Well-Adapted UK report – read the main report on A Well-Adapted UK here.
The Climate Change Committee (CCC) conducted in-house analysis to estimate the investment required to deliver a number of actions identified in the Well-Adapted UK systems.
The analysis used data from research projects on cost-effective adaptation and external literature to estimate the scale of investment needed to deliver key actions out to the 2050s.
The investment analysis does not cover all systems and actions in the Well-Adapted UK report due to data limitations but is intended to provide high-level evidence on the scale of investment required in adaptation.
Key messages
- The investment in adaptation across the UK would need to be around £11 billion per year (range £7–22 billion, 2025 prices), across the actions costed for this analysis. The annual level is roughly equivalent to 2% of the annual investment in the UK in the 2025.
- Roughly two-thirds of this investment can be attributed to three broad categories of actions: passive and active cooling (35% of total investment), flood risk management (21% of total investment) and water storage, efficiency and demand-side measures (11% of total investment).
- Current funding norms would lead to roughly even contributions from the public and private sector. An assessment of the current funding norms of similar actions in each system shows that approximately 36% of this investment is in areas usually funded by the public sector, with 41% likely to fall within private sector delivery, and 23% undetermined.
