Nearly 200 countries agreed on a set of measures at the United Nations biodiversity summit in Yerevan on October 30, aimed at reviving global efforts to halt nature loss by 2030. The two-week conference, known as COP17, sought to address shortcomings in meeting previously established biodiversity targets and to refocus international cooperation on protecting ecosystems critical to sustaining life on Earth.
The final agreement came after intense negotiations marked by sharp disagreements over key issues such as funding, subsidies, and enforcement mechanisms. While delegates welcomed the successful adoption of the documents, celebrations were tempered by concerns that the pact fell short of addressing some of the most pressing challenges with sufficient urgency or detail.
COP17 was convened to reinvigorate the 2022 landmark biodiversity framework, which set ambitious goals including protecting 30% of global land and ocean areas, reducing pollution, and providing increased financial support for conservation efforts in developing nations. However, the UN had warned leading into the summit that the world was off track to meet these targets without accelerated action. Many objectives remain unmet, prompting calls from delegates to intensify efforts.
The final text called for “increased action” to tackle the root causes of biodiversity loss but offered countries multiple options without immediate clarity on which would be prioritized. Stakeholders described the agreement as a modest but necessary step. Catherine Weller of Fauna and Flora International said while the text was neither exciting nor detailed, it reflected important consensus. Kirsty Long of WWF International characterized the outcome as having both strengths and weaknesses but ultimately beneficial overall.
Contentious debates occurred over reforming harmful subsidies, with governments pledging in prior commitments to reduce financial incentives supporting activities such as fossil fuel production, intensive farming, and overfishing. Despite some political momentum, little concrete progress was made to redirect the estimated US$2.4 trillion annually spent worldwide on practices detrimental to biodiversity. An Lambrechts from Greenpeace International emphasized the urgency of shifting such funding toward nature restoration.
Financing for conservation initiatives also triggered disputes amid tightened public budgets and global crises including the energy crunch and conflicts in Ukraine and the Middle East. Experts estimate an annual funding gap of US$700 billion is needed to adequately restore ecosystems and protect endangered species. The European Union urged wealthier emerging economies, including China, to contribute more, a demand met with reluctance by some parties. The summit’s draft texts instead invited these nations to voluntarily signal interest in supporting global biodiversity finance without mandating contributions.
Additional challenges arose around efforts to refine the lacustrine Cali Fund, a UN mechanism created in early 2025 to raise US$1 billion annually by redistributing profits from corporations using genetic resources derived from plants and other organisms. As of the summit, the fund had secured only about US$10,000 in contributions.
Scientific assessments also became a point of contention, with certain countries accused of obstructing the formal acceptance of findings by UN-backed biodiversity bodies, complicating consensus on the severity and causes of nature loss.
Despite these hurdles, COP17 concluded with a renewed, though cautious, commitment to accelerating global biodiversity protection measures in hopes of meeting the 2030 targets. Observers underscored the need for sustained political will and increased financial resources to overcome entrenched obstacles and reverse decades of environmental degradation.
