ERM's Keryn James on how partnerships and tech accelerate sustainability

Keryn James is the CEO of ERM, the world's largest sustainability advisory firm. The company is well-known for its acquisitions and its technology use to implement measurements and optimizations for sustainability. James sees "tremendous momentum in the last five to ten years in sustainability," but "one of the things that's really difficult for companies is operationalizing sustainability" — which means it's a major area of focus and opportunity.

"If you take something like climate change, for example, it's very important that you have the full range of people across the organization involved in the conversation," she noted.
