Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment her Department has made of the potential (a) merits and (b) costs of linking the UK's Emissions Trading Scheme (ETS) to the EU's ETS.

The Government recognises the importance of international co-operation on carbon pricing, and is keen to work with European partners to understand better the interactions between the UK Emissions Trading Scheme (ETS) and the EU Emissions Trading System as they expand and develop in parallel. In this context, the Government remains open to the possibility of linking the UK ETS internationally.
