A firm’s decision to initiate Scope 3 emissions disclosure not only reflects the firm’s sustainability efforts but also signals its commitment to decarbonization, fostering collaboration among suppliers in promoting greener supply chains. Using a generalized difference-in-differences research design, we find that suppliers reduced greenhouse gas emissions following their customers’ initiation of Scope 3 emissions disclosures. This reduction in emissions is more pronounced when the supplier poses greater climate risk and when the customer has a greater need to restore public trust for its climate-related behavior. We also find that this effect varies with the strength of the customer supplier relationship and customer substitutability. Additional analyses suggest that the effect is not solely driven by direct customer monitoring and is robust to excluding customer-supplier pairs likely subject to common shocks. Overall, our results are consistent with Scope 3 emissions disclosures playing a role in promoting more sustainable supply chains.
