Top companies regard climate change as an opportunity to get closer to suppliers—effectively reducing both costs and carbon in their supply chains. Global executives increasingly identify the environment, including climate change, as a top concern. When it comes to purchasing, however, it appears that companies aren’t necessarily translating the importance they place on climate change into action. A McKinsey survey of more than 2,000 global executives finds that while nearly half of respondents say that climate change is a somewhat or very important issue to consider in purchasing and supply chain management, fewer than one-quarter report their companies always or frequently take climate change into consideration in these areas.
