Big Buyers for Climate and Environment is a European Commission Initiative for promoting collaboration between big public buyers in implementing strategic public procurement for sustainable solutions. ICLEI and EUROCITIES are currently running the initiative on behalf of the European Commission, DG Internal Market, Industry Entrepreneurship and SMEs (DG GROW). The initiative aims to work together with existing networks and organisations active in this area and is following the successful piloting of three working groups between 2019 and 2020 within the previous Big Buyers Initiative.
