In this study, numerous options for the further development of competition law were explained. In doing so, the protection of competition remains the point of reference. The options can be assigned to four basic patterns: Sustainability awareness, sustainability boost, competition as sustainable competition and levelling approach. The multitude of options and their very different intensity - sometimes the current state of the law is clarified, sometimes tools and procedures are introduced - already indicates the scope for the European legislator under this topic. With increasing expectations for companies to assume greater responsibility for achieving the Sustainable Development Goals, it seems appropriate to further develop the legal framework.
