19th November 2025

39 Essex Chambers’ barrister Christopher Moss discusses the UK Emissions Trading Scheme (“UK ETS”) with Dr Diana Casey, the Executive Director of Energy and Climate change at the Mineral Products Association, a board member of the Emissions Trading Group, and chair of the Emissions Trading System Policy group for the Emissions Trading Group. 

Dr Casey provides an overview of the UK ETS, its scope and purpose in achieving Net Zero before discussing opportunities and challenges, as well as how to measure the success of the UK ETS. 

Correction Note: At 15:50 and 21:34, Christopher’s reference to the UK ETS having been in place for “almost four years” should be “almost five years”.
