This brief provides details about a project to create a guide to help businesses develop accurate and actionable inventories for their value chains. The planned guide represents the first attempt to adapt, apply and align methods and data used at national and local scales in ways that are tailored to the private sector’s need to undertake mitigation strategies.

The guide seeks to build on existing reporting standards for greenhouse gas emissions, enabling combined reporting, strategy development and mitigation actions to help advance agendas to address both climate change and air pollution.

SEI, the Climate and Clean Air Coalition and IKEA are partners in the project. SEI is using its knowledge and experience in quantifying air pollution emissions at national and local scales to develop the guidance. IKEA and the Climate and Clean Air Coalition are providing funding.

The guide is designed to give businesses with both simple and complex global value chains a tool to take actions to help reduce air pollution emissions, which harm human health. The project aims to set out a rigorous approach to quantifying air pollutant emissions so that companies can credibly document and report on their emission reduction efforts to their shareholders and the general public.

Project partners intend to make a draft of the guidance available in November 2021 at COP26. IKEA and possibly other businesses then plan to test the guidance, which is expected to be published in its final form in 2022.
