Growing pressure from regulators, investors, and other stakeholders is compelling companies to take a deeper look at their scope 3 emissions and develop meaningful disclosures and reduction targets. But, while more and more guidance on how to report on those emissions is beginning to coalesce, many companies still have a lot more questions than answers on where to begin, how to quantify and prioritize, and how to set meaningful reduction goals. Scope 3 emissions can be especially challenging to quantify, and the availability of good data from suppliers and other stakeholders is often lacking or non-existent. Thankfully, by leveraging life cycle assessment data and associated emissions factors, companies can create defensible scope 3 GHG emissions inventories, identify hot spots and areas for improvement, and set realistic reductions goals and targets achievable through partnerships, thoughtful procurement practices, and other strategic initiatives.
