Urenco Annual Report 2022

Streamlined Energy and Carbon Reporting The following disclosures are made pursuant to The Companies (Directors’ Report) and Limited Liability Partnerships (Energy and Carbon Report) Regulations 2018, specifically the requirements for large unquoted companies. Urenco’s greenhouse gas accounting approach is based on operational control. The data in this section relates to Urenco’s UK businesses for the year 2022, with comparative data for 2021. These include Urenco Limited, Urenco ChemPlants Limited, Urenco Enrichment Company Limited, Urenco Nuclear Stewardship Limited and Urenco UK Limited. These businesses are based at two sites, an enrichment and operations facility in Capenhurst and a large office in Stoke Poges. Further energy and carbon disclosures relating to the whole Group can be found within the Strategic Report on pages 26 and 36. UK energy consumption and greenhouse gas emissions Approximately 91 % of our UK energy use in 2022 related to the consumption of purchased electricity (2021: 91 % ). The main source of scope 1 emissions is combustion of natural gas for office heating and for deconversion processes in our new Tails Management Facility.

All of the purchased electricity is bought under a ‘Zero Carbon for Business’ (nuclear) tariff supplied by eDF, which we consider to be carbon free at the point of generation. Hence the emissions associated with the purchase of electricity calculated by applying the ‘market-based’ carbon factor, which take into account any contractual arrangements with energy suppliers, are zero. (2) The amounts in 2021 for diesel for generators have been restated from 0.23 GWh to 0.20 GWh and from 59 tonnes CO 2 e to 51 tonnes CO 2 e due to the correction of input data during the data verification process of compiling 2022 data. Emissions intensity Tonnes CO 2 e/tSWU (3) UK output in 2022: 7.78 (location based reporting) (2021: 8.59) (0.72 tonnes CO 2 e/tSWU in 2022 (2021: 0.72) if the carbon benefit of purchasing ‘blue’ (nuclear) electricity is taken into account under market-based reporting). This has been chosen as it is the primary method Urenco uses to measure production output. (3) SWU: separative work units, as defined on page 181.
