The NHS Net Zero Supplier Roadmap is a strategic timeline that mandates all suppliers to the NHS align with its goal of reaching Net Zero by 2045, requiring escalating levels of carbon reporting and commitment milestones. Since April 2024, the NHS has required a Carbon Reduction Plan (CRP) for all new procurements, with future milestones in 2027 and 2028 demanding full global Scope 1, 2, and 3 reporting and product-level carbon footprinting. Energy Attribute Certificates (EACs)—specifically REGOs in the UK—relate to this roadmap as the primary mechanism for suppliers to address their Scope 2 emissions; by purchasing these certificates, companies can utilize the "market-based" reporting method to formally account for renewable electricity use, which reduces their reported carbon footprint and demonstrates the active progress toward Net Zero required to maintain status as an eligible NHS supplier.
