Corporate heat pledges are emerging as a business response to extreme heat, but they are not the same as carbon reduction or net-zero commitments. Instead of focusing on cutting emissions, heat pledges aim to prepare companies for rising temperatures, protecting workers, facilities, and operations. This Q&A with climate risk advisor Mark Trexler explains why heat pledges are gaining attention and where they can go wrong. Trexler warns that heat pledges can become performative if companies focus on sensors, dashboards, and reporting instead of actual resilience. He also points out that adding more air conditioning may fail if the grid cannot handle the load during peak heat events. Passive cooling measures, such as better airflow and building design, deserve more attention. For CIOs, the relevance is practical: data center cooling, facility monitoring, and long-term climate risk planning all sit within this space. The article also covers OSHA heat enforcement, the limits of voluntary corporate commitments, and why companies should engage with policymakers and customers on climate. The pre-mortem exercise, imagining how a company could fail by 2035 because of climate change, is a concrete way to make the risk real. For anyone tracking corporate climate strategy, this is a useful look at the gap between pledge language and operational reality.
