On April 15, ISDA and 41 other trade associations sent letters to UK government and the European Commission highlighting the importance of linking the new UK Emissions Trading System and the EU’s Emissions Trading System as soon as practicable. Linkage will benefit both parties, and allow both the UK and EU to reach net zero faster and more cost effectively. The advantages of linkage are clear in terms of liquidity, price discovery and the ability to attract abatement from across a larger area. It would also create a level playing field in terms of carbon pricing, avoiding competitive distortions and leading to aligned cost implications for the industry across the UK and European Economic Area.
