In the terms of the Greenhouse Gas Protocol, this is called ‘market-based’ reporting - as opposed to ‘location-based’ reporting.

Following the location-based methodology (which is required to be also 2 reported under SECR alongside market-based figures), our 2022 emissions from electricity were 955.80 tCO2e (including Revenue (£m) 344 379.9 10% transmission and distribution losses), giving total annual emissions of 3,779.67 tCO2e and an intensity of 9.95 tCO2e per £m revenue. The electricity emissions figure above of 80 tCO2e is from grid transmission and distribution losses. Intensity: (tCO2e per £m) 5.25 7.64 46% Boundary, Methodology and Exclusions An ‘operational control’ approach has been used to define the Greenhouse Gas emissions boundary. This approach GHG by scope (tonnes CO2e) captures emissions associated with the operation of all buildings such as warehouses, o昀케ces, and manufacturing sites, plus company-owned and leased transport. This report covers UK operations only, as required by SECR for Non-Quoted Large Emissions source 2021 2022 Share (%) YoY Companies. This information was collected and reported in line with the methodology set out in the UK Government’s variance (%) Environmental Reporting Guidelines, 2019. Emissions have been calculated using the latest conversion factors provided by the UK Government. There are no material omissions from the mandatory reporting scope.
