This year’s 30th United Nations Climate Conference, the Conference of the Parties (COP30), took place in November in Belém, Brazil. As one of the most significant annual gatherings in the field of international climate governance, the Conference brought together state representatives, international organisations, private sector actors and civil society to advance global climate action. Hatice attended the COP30 as part of the University of Vienna delegation, where she followed negotiations and engaged in discussions with a particular focus on carbon markets and climate finance.
Atmosphere and General Impressions
COP30 had a dynamic and engaging atmosphere. Belém, located at the heart of the Amazon region, provided a powerful backdrop for discussions on climate action, responsibility and global cooperation. The sense of urgency was tangible — not only in the negotiation rooms, but also in the corridors, side events, and informal exchanges that often shape climate diplomacy just as much as formal decisions.
The Conference hosted a wide range of fruitful side events, bringing together policymakers, academics, private sector representatives and civil society. These sessions allowed for deeper, more technical discussions beyond the formal agenda and offered valuable insight into how climate commitments are being translated into practice.
Focus on the Carbon Market and Climate Finance
My primary focus during COP30 was the carbon market and climate finance. I engaged with representatives from various ministries and regulatory bodies, listening closely to their jurisdictions, national policies and implementation strategies. These exchanges were particularly valuable in understanding how different countries interpret and operationalise international climate rules within their domestic legal frameworks.
While the core framework for international carbon markets under Article 6 of the Paris Agreement was largely finalised in previous COPs, discussions in Belém made it clear that important gaps remain. In particular, questions surrounding market integrity, transparency, authorisation procedures and the legal nature of carbon credits continue to generate debate. As a result, issues relating to Article 6.2 cooperative approaches and Article 6.4 mechanisms were discussed extensively throughout the Conference, both in formal negotiations and expert-led side events.
Closely linked to carbon markets, climate finance was another central theme at COP30. Expectations were high regarding progress on mobilising finance for mitigation and adaptation, particularly for developing countries. Discussions focused on the effectiveness of existing financial mechanisms, the role of private finance and the long-term credibility of climate-related investments. These debates highlighted the growing intersection between public international law, private finance and market-based climate instruments.
Loss and Damage and Broader Expectations
Beyond markets and finance, loss and damage remained an important – though sensitive – topic. The operationalisation of the Loss and Damage Fund and questions regarding its governance, accessibility and funding sources were repeatedly raised. While COP30 did not resolve all outstanding concerns, it reinforced the political importance of addressing climate impacts that go beyond adaptation and mitigation.
Outcomes and Reflections on Climate
Overall, the outcome of COP30 can be described as incremental but meaningful. Rather than producing dramatic breakthroughs, the Conference consolidated existing frameworks, clarified technical issues and strengthened dialogue between states and non-state actors. From a legal and financial perspective, COP30 confirmed that the future of climate governance will increasingly depend on credible markets, robust regulatory design and cross-border cooperation.
On a lighter note, one of the most talked-about informal moments of the Conference concerned the debate over the location of the next COP negotiations, with Australia and Türkiye emerging as leading contenders. Placing their delegations next to each other was widely seen as a smart — and amusing — diplomatic move by the UN, reflecting the balance between serious negotiation and human interaction that defines COPs.
In sum, COP30 in Belém was a valuable and inspiring experience, particularly for those working at the intersection of climate law, finance and carbon markets. It reaffirmed the importance of legal clarity, financial credibility and international cooperation in addressing the global climate challenge.
