Bonn Climate Conference 2026: Health groups urge tripling adaptation finance to $120 billion by 2035

What Happened

  • At the 64th sessions of the UNFCCC Subsidiary Bodies (SB64), convening in Bonn, Germany (June 8–18, 2026), the Global Climate and Health Alliance (GCHA) called on nations to triple public adaptation finance to at least $120 billion annually by 2035.
  • The $120 billion demand represents a tripling of the $40 billion adaptation finance target established at COP26 in Glasgow (2021).
  • GCHA also demanded national energy transition roadmaps from developed nations for fossil fuel phase-out, and enhanced tracking of loss and damage finance with dedicated reporting mechanisms.
  • Current loss and damage pledges stand at just over $800 million — far below assessed needs for vulnerable nations.
  • SB64 is the first major multilateral climate negotiation since COP30 in Belém, Brazil, and serves as preparatory negotiations for COP31, to be held in Antalya, Türkiye.

Adaptation Finance Under the UNFCCC and Paris Agreement

Under the Paris Agreement (Article 7), all signatory nations are required to engage in adaptation planning, vulnerability assessment, and implementation of adaptation measures. Article 9 obligates developed countries to provide financial resources to developing nations for both mitigation and adaptation. Adaptation finance specifically covers investments to reduce the vulnerability of human and natural systems to actual or anticipated climate change effects.

  • At COP26 (2021, Glasgow), developed countries agreed to at least double adaptation finance from 2019 levels ($18.8 billion) to approximately $37.6–40 billion by 2025.
  • The New Collective Quantified Goal (NCQG) was established at COP29 (Baku, 2024): developed nations committed to $300 billion per year by 2035 in total climate finance; critics and developing nations argued adaptation's share within this was insufficiently ring-fenced.
  • The Cancun Adaptation Framework (2010) first established the institutional architecture for international adaptation support under the UNFCCC.

Connection to this news: GCHA's demand for $120 billion specifically for adaptation highlights the longstanding gap between pledged climate finance and the dedicated adaptation portion — the $300 billion NCQG does not guarantee a tripling of adaptation funding unless explicitly structured that way.

Global Climate and Health Alliance (GCHA)

The GCHA is a global coalition of health organisations advocating for health-centred climate policy. It represents hundreds of health professional groups, research institutions, and civil society organisations across multiple countries. It participates in UNFCCC negotiations as an accredited observer, making formal representations at COP and SB sessions.

  • GCHA argues that climate change is fundamentally a public health crisis — affecting disease burden (malaria, dengue, cholera), food and water security, heat mortality, and healthcare infrastructure.
  • The Alliance's policy framing connects inadequate adaptation finance directly to preventable deaths in the Global South.
  • GCHA's Jess Beagley stated: "Without adaptation finance, life-saving investments in health systems and in health-determining sectors such as water and sanitation, disaster planning, and food systems will remain out of reach."

Connection to this news: GCHA's formal demand at SB64 elevates the health-adaptation finance nexus from a side-event concern to a core negotiating position ahead of COP31.

SB64 and the UNFCCC Subsidiary Body Process

The UNFCCC's subsidiary bodies — the Subsidiary Body for Scientific and Technological Advice (SBSTA) and the Subsidiary Body for Implementation (SBI) — meet twice a year (mid-year in Bonn; end-year at COP). They prepare technical and policy groundwork for COP decisions. The SBs do not adopt binding decisions independently; their outputs are recommendations for COP adoption.

  • SB64 agenda includes: operationalising the 59 Belém Adaptation Indicators (agreed at COP30); National Adaptation Plans (NAPs); fossil fuel phase-out roadmaps; agricultural climate action; and biodiversity-climate-land nexus.
  • India participates actively in SB sessions as part of the G77+China bloc, which collectively advocates for increased climate finance and differentiated responsibilities.
  • The Belém Adaptation Indicators represent the first agreed framework for measuring global progress on adaptation under the Paris Agreement's Global Goal on Adaptation (GGA).

Connection to this news: The operationalisation of the Belém Adaptation Indicators at SB64 creates the technical measurement architecture that will determine whether the $120 billion (or any adaptation finance target) is actually achieving health and resilience outcomes on the ground.

Loss and Damage Finance

Loss and damage refers to the irreversible or difficult-to-adapt-to impacts of climate change — such as permanent inundation of low-lying islands, loss of livelihoods, or climate-driven displacement. It is legally and conceptually distinct from adaptation (which addresses future risks) and mitigation (which reduces emissions).

  • The Santiago Network (established COP25, 2019) facilitates technical assistance on loss and damage.
  • The Fund for Responding to Loss and Damage (FRLD) was operationalised at COP28 (Dubai, 2023), with initial pledges. By SB64, pledges total just over $800 million — a fraction of the hundreds of billions estimated as needed annually.
  • Developing countries, particularly SIDS (Small Island Developing States) and LDCs (Least Developed Countries), are the primary advocates for robust loss and damage finance.

Connection to this news: GCHA's demand for enhanced loss and damage tracking underscores that the $800 million in current pledges falls dramatically short of health-sector needs alone, let alone broader economic and infrastructure losses.
