Mitigating and adapting to climate change is a vital challenge that cannot rely solelyon technology or macro policies but need also be tailored to local social and ecologi-cal contexts. As theory suggests, institutional designs that increase collective climateaction could potentially speed up climate action in society. In this article we explorethe concept of ‘community climate commons’ (CCCs) to foster interconnected andholistic approaches involving citizens and civil society in addressing climate change.Based on a systematic literature review, the aim is to further develop the concept ofCCCs and to identify key features for the successful establishment of CCCs for thepromotion of collective climate action. The results identify four key features forCCCs: (1) democratic organization with transformative leadership, (2) small groupsizes with clear boundaries and existing rules-in-use for participation, (3) access toorganizational structures, meeting places, social capital, collective identity, and socialcohesion, and (4) external financial, political, and social support. In conclusion, CCCshave a real potential to foster a wider societal mobilization of collective climateaction while simultaneously addressing other issues of concern in local communities.
