CircularInvest is a CCRI-PDA initiative proposed by 4 organisations (META, INOVA+, Circle Economy and ICLEI EURO) that aims provide project development assistance (PDA) to selected circular economy (CE) project promoters from across Europe so as to access the resources needed to develop significant CE investment projects at local and regional scale and to close the investments during the action. In the proposal phase, CircularInvest collected signed support letters from European cities that wish to benefit from the CircularInvest PDA services with an overall investment volume exceeding €20M.
