In order to break the link between economic growth and environmental degradation, municipalities need to change their purchases. Our project will contribute to reducing municipalities' purchase-generated (Scope 3) emissions according to set goals and strengthen the link to the circular economy. Municipalities will analyse their emissions and then, together with industry, create measures to reduce these emissions. One measure is to design a support structure that invites SMEs to dialogue early in the purchasing process in order to tighten cross-sectoral requirements regarding the environment, but also regarding social sustainability. The project will 1) analyse and select the procurement areas that can have the most impact on emission reduction within Scope 3, 2) in dialogue with SMEs tighten the requirements in procurements to achieve the greatest impact on Scope 3 emissions but at the same time strengthen companies to enter the circular economy and social sustainability, and 3) create a purchasing process in municipalities that contributes to a circular economy.
