95% of directly procured UK office energy from certified renewables in FY21Data confidence — high

In FY21, 95% of all energy procured directly from energy suppliers for EY's UK offices was from certified renewable sources — electricity backed by Renewable Energy Guarantees of Origin (REGOs) and biogas certified under the Green Gas Certification Scheme. This approach reduces market-based Scope 2 emissions materially below the location-based figure. The firm applies DEFRA/DECC UK grid average conversion factors to all electricity purchased for location-based reporting, while also separately calculating market-based Scope 2.
