Supplier Engagement Assessment 2025

CDP’s annual Supplier Engagement Assessment (SEA) – formerly known as CDP's Supplier Engagement Rating (SER) – evaluates corporate supply chain engagement on climate issues. This assessment is based on the information reported by companies in their CDP response, and evaluated under the criteria of the Supplier Engagement Assessment Methodology. Companies that have achieved an A in their SEA are celebrated in the table below.

By engaging their suppliers on climate change, these companies are playing a crucial role in the transition towards the net-zero sustainable economy.
