Asset owners across the UK, Europe and US are sharpening their focus on asset manager stewardship, and an increasing regulatory focus on stewardship outcomes and transition-focused products is leading investors to think harder about how they can demonstrate that their own engagements are having an effect. Jennifer Walmsley, associate director for corporate engagement at the Institutional Investors Group on Climate Change (IIGCC), has more than two decades of experience in the area, having run the engagement team at EOS at Federated Hermes and headed up investor engagement for the Financial Reporting Council. She now oversees IIGCC's corporate engagements, including Climate Action 100+, the Net Zero Engagement Initiative and Nature Action 100. In this episode, Walmsley discusses how investors can measure the impact of their engagements, how to ensure engagement is a value add for company and investor alike, and how IIGCC is aiming to turn ineffective engagements at the collaborative initiatives it looks after into effective ones.
