Maintaining and expanding public goods is synonymous with promoting sustainable development but discussions are needed to clarify how policies need to be coordinated to enable collective action on public goods. Collective action for Public Goods will only be successful if all who partake in such actions can gain complimentary benefits that would be either more costly or impossible to achieve without the collective effort. Such complementary benefits are possible provided all stakeholders contributing to the public good of social peace and social cohesion cooperate with each other and preserve this and other public goods be they citizens, civil society organizations, all public authorities and all business firms. This concerted effort for a good cause can certainly be coined “ethics in action” – a notion which exhibits the moral foundation of the private and public choices inherent in sustainable development implementation of which interactions amongst stakeholders are no longer transactional, but rather aspiring toward greater good. Civil society organizations are key stakeholders producing, maintaining, and benefitting from Public Goods. They should strive for full inclusion, as there are many people who are either excluded or under-provided with respect to public goods. Public authorities, another key stakeholder group, need to cooperate with other stakeholders through collaborative frameworks and mechanisms for collective action that bind states and international organizations at a global scale. Another important stakeholder group, private and public enterprises need to operate within a level playing field globally, conduct business based on Responsible Business criteria and be welcomed to contribute to Public Goods creation in a sustainable and proactive manner without causing negative impacts due to their business activities. This paper presents and discusses how collective action can be achieved through concerted efforts by all members of society aiming to produce and maintain public goods essential for the sustained and equitable functioning of society. The UN 2030 Agenda for Sustainable Development serves as a shared roadmap in achieving a shared future.
