The Sustainable Stock Exchanges (SSE) initiative is a peer-to-peer learning platform for exploring how exchanges, in collaboration with investors, regulators, and companies, can enhance corporate transparency – and ultimately performance – on ESG (environmental, social and corporate governance) issues and encourage sustainable investment. Since 2012, several other leading exchanges have joined the group of SSE Partner Exchanges. UNCTAD, the UN Global Compact, the PRI and UNEP-FI, as the core organizer of the SSE Initiative, also committed to supporting stock exchanges in this effort. The SSE initiative invites exchanges globally to become a Partner Stock Exchange within the SSE by making a voluntary public commitment to promote improved ESG disclosure and performance among listed companies. http://www.sseinitiative.org
