This document is a guide for suppliers on the completion of Carbon Reduction Plans (CRPs) required for bidding on contracts. It outlines the necessity for suppliers to submit a detailed CRP that includes their organizational carbon footprint and a commitment to achieving Net Zero emissions by 2050. The guide specifies that the CRP must be tailored to the bidding entity, although it may encompass the parent organization under certain conditions. It emphasizes the importance of regular updates to the CRP, which should be published on the supplier's website and approved by senior leadership. The document also provides a template for the CRP and details the baseline emissions calculations, including Scope 1, 2, and 3 emissions. Furthermore, it discusses the reporting requirements and the need for suppliers to adopt key objectives from the CRP into their strategic plans. The guidance aims to ensure compliance with environmental standards and to promote transparency in emissions reporting.
