The objective of the study was to map, assess and report on current levels of take-up of CSR codes of conduct and internal action plans for CSR and sustainability within European SMEs and start-ups, paying particular attention to variations between Member States, regions of Europe and specific sectors of the economy. This document presents a collection of good practices, which includes 30 cases of SMEs and start-ups that have successfully designed and implemented CSR and sustainability-related activities. These good practices were identified by screening existing sustainable business models and activities (via survey responses, expert recommendations, awards and certificates obtained by the SME, etc.). The portfolio of the selected good practices presents illustrative examples of relevant and replicable dimensions of CSR and sustainability activities of SMEs.
