Responsible investing has increasingly become an important part of managing assets. Pension funds are implementing strategies and processes to ensure environmental, social, and corporate governance (ESG) factors are taken into consideration as investments are made. But what impact does the integration of ESG factors have on performance and costs? Many studies have been done on how to best measure the impact of responsible investing on portfolios and it has proved to be a difficult task as performance databases and ESG data sets are often unconnected. In this research, CEM seeks to provide insights to answer this key question by drawing upon data from its database and analysis from its team.
