The Pledge was launched on 25 September 2014 at PRI in Person in Montréal, and is supported by the Principles for Responsible Investment (PRI) and the United Nations Environment Programme Finance Initiative (UNEP FI). Overseen by the PRI, it has attracted commitment from over 120 investors with over US$10 trillion in assets under management, as of the United Nations Climate Change Conference (COP21) in December 2015 in Paris. Support for the Montréal Carbon Pledge comes from investors across Europe, the USA, Canada, Australia, Japan, Singapore and South Africa. The Montréal Carbon Pledge allows investors (asset owners and investment managers) to formalise their commitment to the goals of the Portfolio Decarbonization Coalition, which mobilises investors to measure, disclose and reduce their portfolio carbon footprints. Over US$100 billion has been committed to this as of COP21.
