Guidance on Carbon Quantification Tools for Acquisition

This document is a Safety and Environmental Bulletin (SEB) that provides guidance on the use of carbon quantification tools in environmental management for acquisition processes. It outlines the purpose of carbon tools, which are digital calculation tools that convert activity data into carbon emission values, typically expressed in kilograms of carbon dioxide equivalent (kg CO2e). The SEB details how these tools can assist decision-makers in understanding carbon emissions associated with products, systems, and services (PSS) throughout various lifecycle phases, including Pre-Concept, Concept, Assessment, Demonstration, Manufacture, In-Service, and Disposal. It emphasizes the importance of selecting appropriate carbon tools aligned with lifecycle assessment (LCA) standards and provides criteria for evaluating the effectiveness of these tools. Additionally, the document discusses the significance of using robust emission factors and the need for transparency in calculations to ensure accurate carbon quantification. Recommendations for sourcing carbon tools and considerations for their application are also included.
