Our inaugural meeting at COP28, hosted by BND, gathered green finance leaders from institutions including Allianz, HSBC, ICMA, J.P. Morgan DFI, Moody's, Morningstar Sustainalytics, MSCI, and Nomura.
Impact Disclosure Taskforce
We are part of the Impact Disclosure Taskforce convened by J.P. Morgan and co-chaired by J.P. Morgan and Natixis, developing better use of sustainable finance definitions, recommendations for service providers on how to use them, and a joint data utility.
Industry publications
Our work on publications relevant for the intersection of AI and sustainable finance include an upcoming book chapter and white paper on the complexity and divergence of sustainable finance definitions with Dr Richard Perkins of the London School of Economics.
