From words to action: Governments must use the UN tax talks to deliver fair global tax rules and climate finance

As the fourth round of UN Tax Convention negotiations concluded on Friday, governments face a defining choice: seize this once-in-a-generation opportunity to reform global tax rules so they work for people and planet – or retreat to defending systems that are failing to deliver fairness, justice and adequate revenues for combating the most pressing challenges of today.[1]

Nina Stros, Global Senior Policy Expert at Greenpeace International’s Political Unit, said:

“This round of UN Tax Convention negotiations saw the liveliest debates so far on reforming global tax rules to enhance climate action, sustainable development and hold the super-rich to account. It’s clear that the game is now on for securing a strong outcome on taxing the world’s biggest polluters.

“As fossil fuel-driven floods, storms and hurricanes hit more and more countries, and inequality widens as the world approaches its first trillionaire, negotiators are starting to wake up to the huge opportunity. The UN Tax Convention is a once-in-a-generation chance to shift investment away from polluting activities, redistribute wealth, and raise hundreds of billions for climate resilience and public services – without adding to the tax burdens of citizens and consumers.”

Greenpeace International’s key takeaways from INC-4:

• Supportive countries must now come together as part of a high-ambition coalition to put forward tangible proposals to strengthen the Convention text on sustainable development and the commitment on taxation of high-net-worth-individuals (HNWIs), as well as rally others to get on board. This must be matched by much stronger support, particularly from European countries, on the issue of reallocating taxing rights, which is crucial for clamping down on corporate tax dodging and boosting public revenues in most countries.

• Concerns around transparency also continued through the talks this month as civil society groups remain locked out of key online intersessional meetings, despite the Terms of Reference mandating openness and inclusivity. Given what’s at stake, these sessions must be opened up to observers, enabling scrutiny and accountability – especially in light of the threat that not all written submissions by countries will be made public. The Chair and Secretariat also now need to put forward bracketed text options reflecting verbal and written submissions from countries, to enable more detailed discussions in the coming months.
  
  

“Action on fair global tax rules that hold polluters to account is a no-brainer. Countries are losing hundreds of billions of dollars each year to multinational and super-rich profit shifting. This action is also hugely popular with the public across right and left-wing voters, as extensive polling has shown. Governments must not settle for vague language that protects the status quo, a fair and sustainable economy is at stake,” Stros adds.

The Intergovernmental Negotiating Committee (INC) Fifth Session will be from 3 to 13 August 2026 in New York.
