GPP-STREAM builds on the idea that interregional cooperation can help mainstreaming GPP policies within the administrations involved and ensure that resource efficiency measures are spread and benefits acknowledged. The project aims to improve the management, implementation and monitoring of policy instruments that integrate GPP approaches so as to ensure that resource efficiency gains can be maximized and that resource efficiency objectives are institutionalized through GPP. The project is coordinated by Region Friuli and is implemented in partnership with 8 Bulgarian, Spanish, French, Italian and Romanian bodies that have complementary environmental and GPP expertise.
