Collective Action at the Basel Institute on Governance

The story behind the Basel Institute's support for Collective Action against corruption and this online knowledge hub.

Anti-corruption Collective Action takes many forms. At its heart, it is about bringing businesses and other stakeholders together to tackle shared problems of corruption.

Collective Action initiatives and tools can help to:

  • raise standards of integrity in an industry or market;
  • develop self-regulatory standards for specific sectors;
  • solve systemic issues related to corporate bribery and corruption;
  • enhance fair competition and level the playing field between competitors.

Whatever the goal, Collective Action requires trust and a willingness to collaborate constructively. Both are often based on sustained cooperation between stakeholders in the private and public sectors, civil society and international organisations.

About this knowledge hub

The B20 Collective Action Hub is a global resource centre on anti-corruption Collective Action. It offers a range of anti-corruption publications and tools, plus a database of over 280 Collective Action initiatives and projects designed to raise standards of integrity and fair competition.

The B20 Hub was launched in 2013, following a mandate from the B20 group of business leaders for the Basel Institute to develop and maintain this hub in collaboration with our institutional partners. It has developed and expanded over the years thanks to support from our key donors and partners, in particular the Siemens Integrity Initiative.

All resources are freely accessible and a helpdesk function is available for users to ask specific questions.
