This document is a guide for suppliers required to submit a Carbon Reduction Plan (CRP) as part of their bidding process for contracts. It outlines the requirements for the CRP, which must detail the supplier's organizational carbon footprint and commitment to achieving Net Zero emissions by 2050. The guide specifies that the CRP should be tailored to the bidding entity, although it may include the parent organization under certain conditions. Suppliers are advised to develop their own CRP promptly and ensure it is updated regularly, with annual publication on their UK website. The document also includes a template for the CRP and emphasizes the need for approval by senior leadership to demonstrate commitment. Additionally, it provides information on baseline emissions calculations and outlines emissions reduction targets for the future. The guide concludes with a declaration section for sign-off by the supplier's management.
