This document discusses socially responsible investment (SRI). It defines SRI as incorporating environmental, social and governance factors into investment decisions, rather than focusing solely on financial factors. It describes various forms of SRI, including SRI funds that select companies meeting financial and non-financial criteria, negative screening funds that exclude certain sectors, shareholder activism, and thematic funds focused on sustainability issues. The objectives of SRI investors are either controlling long-term risks and improving returns, or combining investing with ethical values like excluding tobacco or arms companies. The number of institutional and individual investors using SRI approaches is growing internationally.
