SI 2019/107. The Greenhouse Gas Emissions Trading Scheme (Amendment) (EU Exit) Regulations 2019. Comes into force on Brexit day. These Regulations amend amendments to the Greenhouse Gas Emissions Trading Scheme Regulations 2012 (SI 2012/3038). The functioning of the EU Emissions Trading Scheme depends on the monitoring and reporting of emissions by participants for each scheme year. It also requires the surrender by participants of a corresponding number of allowances in relation to their emissions for each scheme year. The issuing and surrender of allowances is dependent on EU systems and infrastructure, as such that aspect of the scheme will cease to apply to UK operators after the 2018 Scheme year in a no deal scenario. The monitoring, reporting, accreditation and verification obligations will continue to apply.
