While the Net Zero Asset Managers Initiative commitment (the NZAMI Commitment) is a clear signal to the market of an asset manager’s commitment to addressing the risks and challenges of climate change, it is a significant undertaking for asset managers and has several regulatory implications. Compliance may be particularly challenging for asset managers with large existing books of business or that do not have legacy environmental, social, and governance (ESG) or impact-investing product offerings. Notably, adopting a NZAMI Commitment requires asset managers to address issues with respect to fiduciary duties, fund and/or strategy disclosure documents, advertising and marketing, guideline monitoring, engagement and proxy voting, as well as client reporting, among other considerations.
