COP31: the climate summit in Türkiye

The 31st Conference of the Parties to the UN Framework Convention on Climate Change meets in Antalya in 2026.

The COP (Conference of the Parties) is the decision-making body where the roughly 200 parties to the UN climate convention meet every year. The Paris Agreement, the goal of limiting warming to 1.5 °C and countries’ nationally determined contributions (NDCs) are all shaped at these summits.

Purpose: the “COP of Implementation”

The theme of Türkiye’s presidency is turning existing decisions into concrete, measurable results on the ground rather than adding new pledges. The presidency is built on three principles: dialogue, consensus and action.

Key topics in the negotiations

  • New national climate plans (NDCs) following the Global Stocktake
  • The Global Goal on Adaptation and climate resilience
  • Just transition
  • The roadmaps raised at COP30 on transitioning away from fossil fuels and protecting forests

Türkiye’s Action Agenda

Priorities include the clean energy transition, industrial transformation, climate-resilient cities, agriculture, climate finance and Zero Waste. The “Climate Implementation Bridge” initiative, which aims to connect national climate plans with investment and finance, is also part of the agenda.

    Global climate change

    Burning fossil fuels, deforestation and industrial processes have pushed atmospheric greenhouse gas concentrations to their highest level in at least 800,000 years. The Intergovernmental Panel on Climate Change (IPCC) now states that warming is “unequivocally” caused by humans.

    The consequences go well beyond rising temperatures: heatwaves, droughts, heavy rainfall, sea level rise, ocean acidification and melting ice form a system in which each change reinforces the others.

    Industry and climate

    Heavy industries such as steel, cement and lime account for a large share of global emissions. Carbon capture, energy efficiency and low-carbon production in these sectors are among the hardest, yet most decisive, steps towards climate goals.

    Human impacts on ecosystems

    Human impact reaches far beyond the climate. Land-use change, overexploitation, pollution and invasive species began reshaping ecosystems even before climate change did. According to IPBES, changes in land and sea use are the largest driver of nature’s decline.

    The Stockholm Resilience Centre’s planetary boundaries framework defines nine limits for a safely functioning Earth system. Recent assessments find most of them already crossed: climate, biosphere integrity, nitrogen and phosphorus cycles, freshwater, land use and novel chemicals.

    The Anthropocene: the human epoch

    The Anthropocene is a proposed term for the period in which human activity has left a lasting mark on Earth’s geological record. Popularised in 2000 by Nobel laureate chemist Paul Crutzen, it has become a shared language across science, philosophy and the arts.

    The Anthropocene Working Group proposed the 1950s as its starting point, citing radioactive fallout from nuclear tests, plastics and fly ash from fossil fuels as markers of this “golden spike”. In 2024, however, the International Union of Geological Sciences (IUGS) declined to adopt it as a formal geological epoch.

    So the Anthropocene is not yet an official unit of geological time. Even so, there is broad scientific agreement that we live in a period in which humans are transforming the planet. The debate is about what to call this transformation and where to say it begins.

    The sixth mass extinction

    Earth’s history includes five great extinctions, in which most species disappeared within a short span of geological time. Their causes were volcanism, climatic shifts and an asteroid impact.

    Many scientists believe today’s rate of species loss is tens to hundreds of times higher than the natural background rate, and that we may be on the threshold of, or already in, a sixth mass extinction. This time, the cause is human.

    The question is scientifically debated: some researchers stress that species loss has not yet reached the scale of past extinctions. But there is wide agreement that the trend is alarming.
