The strategic partnership will see Glass Lewis integrating ESG research and ratings from Sustainalytics in to data for more than 10,000 companies on its proxy research and vote management platform.
The companies will work together to develop a new ESG profile page using Sustainalytics data, which will allow users of the Glass Lewis proxy voting platform to consider ESG factors in their voting policies.
Users will also gain access to a full range of ESG data for analysis, screening and engagement, accessed through a tailored workflow.
Michael Jantzi, CEO of Sustainalytics, said: "The responsibility for ensuring companies are effectively managing the business risks related to environmental and social factors lies squarely with corporate directors."
He added: "Just as portfolio managers and analysts are increasingly integrating ESG factors into their investment processes, those professionals responsible for their firms' proxy voting policies and, ultimately their actual proxy votes, also need insights into how these issues are being managed within the boardroom. We are pleased to be partnering with Glass Lewis to make these important ESG insights more accessible to governance decision-makers."
CEO of Glass Lewis Katherine Rabin commented: "Increasingly, our clients want to better understand how their portfolio companies are managing their ESG risk."
She added: "By combining our governance solutions with Sustainalytics high quality research, extensive data and global scope, we can immediately deliver meaningful ESG insights to Glass Lewis clients, helping them understand and connect with the companies in which they invest."
