COP31 Climate Summit: What to Expect and Why It Matters 2026

COP31, the latest UN climate summit, has convened in Antalya, Turkey, with the world again facing the familiar challenge of accelerating climate change. As representatives from nearly all countries gather, the question is what can be achieved amid repeated warnings that the 1.5C limit will soon be breached.

This year's conference feels like Groundhog Day: wealthy nations are still failing to meet commitments to assist poorer, vulnerable countries, emissions cuts are too slow, and bickering over responsibility continues. Yet there are potential wins to be had, from finalizing rules for carbon markets to boosting adaptation finance.

What is COP31 and why does it matter?

COP31 is the 31st Conference of the Parties to the UN Framework Convention on Climate Change (UNFCCC). It brings together governments, observers, and stakeholders to negotiate and review global climate action.

This year's summit is particularly significant because the UN has acknowledged that the 1.5C temperature-rise limit is set to be breached in just a few years. The Earth is amassing heat at an accelerating pace, making the need for urgent action more pressing than ever.

Key issues on the table at COP31

The agenda is packed with contentious issues. Wealthy countries are under pressure to deliver on climate finance pledges, while developing nations demand greater support for adaptation and loss and damage.

Emissions reduction commitments remain insufficient, and debates over who should shoulder the most responsibility persist. Additionally, the summit will address the rules for international carbon markets and the global stocktake process.

• Climate finance: Wealthy nations must meet their pledges to support poorer countries.
• Adaptation: Scaling up funding for climate resilience in vulnerable regions.
• Loss and damage: Operationalizing the fund agreed at previous COPs.
• Emissions cuts: Strengthening national commitments to align with 1.5C.
• Carbon markets: Finalizing rules to ensure integrity and avoid double counting.

What can COP31 realistically achieve?

Despite the challenging backdrop, COP31 can deliver incremental but important wins. Finalizing the rulebook for carbon markets would provide certainty and unlock finance for sustainable projects.

Progress on the loss and damage fund, including securing initial contributions, would be a tangible outcome for vulnerable nations. Moreover, the summit can serve as a platform to ramp up political pressure for stronger emissions targets ahead of the next round of national commitments.

Challenges and obstacles

The absence of the United States under Donald Trump (though even the Taliban are attending) casts a shadow over the talks. The US withdrawal from the Paris Agreement has weakened global momentum, but other countries are stepping up.

Deep divisions remain between developed and developing nations over burden-sharing. Trust is fragile, and any perceived backsliding on finance could derail progress. The background to this story is set out in COP31 Climate Talks: World Leaders Gather for Crucial Summit. A related thread runs through Australia and Turkey Criticized for Hosting COP31 Climate Talks. Earlier coverage in COP31 Host Demands Tangible Climate Progress at UN Summit shows how the argument developed.

What to watch in the coming two weeks

Key moments include the high-level segment where heads of state and ministers will make announcements, and the final negotiations on carbon markets and finance.

Watch for pledges to the loss and damage fund, commitments to phase out fossil fuels, and the outcome of the global stocktake. Civil society and youth activists will also be pushing for ambition.
