The objective of P4SME project is to improve the support in terms of sustainability that European STPs, incubators, innovation agencies or similar organisations are providing to their tenants or client companies. For that purpose, the consortium will identify and analyse tools, programmes or initiatives that might help SMEs to become more sustainable and will implement in the medium-term an efficient method based in those inputs to be applied through pilot actions in their territories. In order to achieve this objective, peer-learning activities are designed to facilitate cooperation and knowledge transfer among the involved STPs (FUNDECYT Science and Technology Park of Extremadura, Johanneberg Science Park, Tallinn Science Park Tehnopol) within the project time frame of one year.
