The International Integrated Reporting Council (IIRC), CDP (previously the ‘Carbon Disclosure Project’) and the Climate Disclosure Standards Board (CDSB) have entered into a Memorandum of Understanding (MoU) to improve their collaboration and promote the global harmonisation and clarity of corporate reporting requirements around natural capital. This MoU follows an earlier MoU between the IIRC and the World Intellectual Capital Initiative (WICI) over intellectual capital.
