Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of potential economic merits of linking UK and the EU Emissions Trading Schemes.

Linking is expected to bring significant economic benefits. It would create a larger, stable carbon market, support British businesses through removing trade barriers, support UK renewable rollout and lower electricity costs.

Linking is expected to facilitate a mutual UK-EU CBAM exemption, removing a major barrier to trade and lowering costs for UK firms. Linking is also expected to support new green industries in the UK and enable cross-border CO2 storage.
