The Conference of the Parties to the United Nations Framework Convention on Climate Change is one of the most consequential forums in contemporary international diplomacy. Unlike committees focused on a single crisis or institution, COP asks delegates to confront a global challenge that cuts across borders, economies, ecosystems, and generations. States must negotiate not only what climate action should look like, but who should lead, who should pay, and how the burdens of a changing planet should be shared.
At GlobalVoices 2026, COP31 delegates will debate two urgent questions at the heart of global climate politics. The first concerns sea level rise and the future of Pacific Island States, where climate change is already threatening land, livelihoods, sovereignty, and cultural survival. The second turns to the language of climate ambition itself, asking whether net zero commitments are enough, or whether states and corporations must move towards absolute zero emissions instead.
The Past
The modern international climate regime began with the 1992 United Nations Framework Convention on Climate Change, which recognised climate change as a shared global problem requiring international cooperation. From the beginning, however, climate diplomacy has been shaped by tension between collective responsibility and unequal contribution. Industrialised states had produced the majority of historic emissions, while many developing countries faced the sharpest consequences despite contributing far less to the problem.
The Kyoto Protocol of 1997 introduced binding emissions reduction targets for developed countries, but its limited scope and uneven participation revealed the difficulty of turning climate concern into enforceable global action. The Paris Agreement of 2015 marked a major shift. Rather than imposing the same obligations on all states, it asked countries to submit nationally determined contributions, creating a flexible framework built around ambition, transparency, and regular review.
For Pacific Island States, climate diplomacy has always carried existential weight. Rising seas, coastal erosion, saltwater intrusion, and extreme weather have placed small island communities at the forefront of global climate advocacy. Their calls for stronger emissions cuts, climate finance, and recognition of loss and damage have helped reshape the moral and political language of climate negotiations.
The Present
In the present day, COP negotiations take place against a backdrop of intensifying climate impacts and uneven progress. Many states have adopted net zero targets, promising to balance emissions produced with emissions removed or offset elsewhere. Supporters argue that net zero provides a practical route for governments and industries to decarbonise over time. Critics, however, warn that poorly defined net zero pledges can delay real emissions cuts, rely too heavily on offsets, or allow high-emitting sectors to continue operating without sufficient change.
At the same time, sea level rise is no longer a distant concern. For Pacific Island States, it is already affecting homes, infrastructure, freshwater supplies, and long-term national planning. The issue also raises complex legal and political questions. If territory becomes uninhabitable, what happens to statehood, maritime boundaries, citizenship, and cultural heritage? Climate change is therefore not only an environmental issue, but a challenge to the foundations of international law and sovereignty.
COP31 delegates will need to consider the competing priorities that shape climate negotiations today. Developed and developing countries often disagree over finance, responsibility, and the pace of transition. Fossil fuel-dependent economies may resist rapid restrictions, while vulnerable states argue that delay carries unacceptable human and ecological costs. The committee will therefore require delegates to balance scientific urgency with political realities.
The Future
Together, these topics push COP31 beyond broad climate promises and into the real consequences of delay, compromise, and action. Sea level rise forces the committee to confront what protection should mean for Pacific Island States, from adaptation finance and relocation planning to legal recognition and deeper emissions reductions. It also places climate justice at the centre of debate, asking whether the countries least responsible for climate change should be left to face its most severe effects.
The debate over net zero and absolute zero raises a different but equally urgent question: what counts as meaningful climate ambition? Delegates will need to weigh the practical role of removals and offsets against the need for deeper structural change that brings emissions as close to zero as possible. This will require careful consideration of environmental targets, economic transition, technological feasibility, and the risk that climate pledges become political cover for insufficient action.
COP31 offers delegates a chance to engage with one of the defining challenges of the present century. The strongest contributions will be those that understand both the science and the diplomacy, recognising that climate negotiations are never just about targets on paper. They are about land, lives, economies, futures, and the difficult work of building agreement in a world where the costs of climate change are profoundly unequal.
