Carbon Reduction Plans (CRPs) are documents required under UK Procurement Policy Note 06/21 for any organisation bidding on major public contracts. Each CRP has to state the organisation's current carbon footprint and commit to reaching Net Zero by 2050, covering Scopes 1, 2, and 3. Scope 2, which covers purchased electricity, is where EACs come in. In the UK these are REGOs (Renewable Energy Guarantees of Origin). Buy enough REGOs and you can report zero emissions for your electricity use under the market-based method. That clears the CRP's reduction targets and ticks the procurement box for green energy sourcing.
