The proposal, launched by Spain and Brazil at the UN's Financing for Development Conference in Seville, marks a historic step toward addressing extreme wealth inequality that threatens both public services and democracy itself.

The initiative aims to ensure a progressive and efficient global tax system with the aim of reducing social inequality. This builds directly on years of union-led tax justice campaigning that has already yielded significant victories, including the OECD global minimum corporate tax, Australia's public country-by-country reporting initiatives, and the ongoing UN tax treaty negotiations.

PSI has been at the Conference in Seville advocating publicly driven development, funded through fairer taxation, through quality public services and governemnt action to tackle the climate crisis.

PSI member unions have been instrumental in pushing Governments to take action on tax justice.

In Brazil, where extreme inequality has been a persistent challenge, union leaders view this development as a significant breakthrough.
