  Sun Life Financial Inc. on Tuesday said its group retirement services unit has launched a proprietary environmental, social and governance evaluation framework aimed at making sustainable investing easier for its clients. 


  The Toronto financial-services company said the framework, which covers the unit's core investment platform of 23 investment managers and more than 140 investment options, will help plan sponsors and members make informed decisions on sustainable investing. 


  Sun Life said it aims to identify ESG-leading managers and funds in every major asset category offered on the unit's core platform using proprietary criteria and to make it easy for plan sponsors to understand the level of ESG integration for the investment options they offer in their retirement savings plans. 


  Sun Life said the framework aligns with its own corporate-wide sustainability plan, adding that it integrates ESG considerations into its own investment process.
