Louisa Guy is a Senior Financial Policy Analyst at the Principles for Responsible Investment (PRI). She leads the UK policy workstreams on financial regulation at the PRI, covering the transition to net zero, advocating for clear Government action on climate change, supporting the adoption of a comprehensive sustainability reporting framework, and the development and effective implementation of a sustainable finance taxonomy. The PRI is the world's leading proponent of responsible investment, and our policy work focuses on the building blocks of a sustainable financial system. The PRI works with its international network of signatories to put the six Principles for Responsible Investment into practice. Its goals are to understand the investment implications of environmental, social and governance (ESG) issues and to support signatories in integrating these issues into investment and ownership decisions.
