Thousands of delegates have gathered in Montreal, Canada, for a once-in-a-decade chance to address the accelerating pace of species loss and the dangers of ecosystem breakdown.

COP15 brings together parties to the UN Convention on Biological Diversity (CBD) with a goal of negotiating this decade’s biodiversity targets and a new global framework for biodiversity protection.
The summit risks being overshadowed by the recently concluded COP27 on climate change, but the issues are linked and the importance of biodiversity protection cannot be overstated.
About one million plant and animal species are at risk of extinction. Not only are our activities driving this mass extinction, its consequences also threaten our own health and survival.
COP15 needs to mark a step change in how quickly and how seriously the international community responds to catastrophic nature loss. The focus is expected to be on 30×30, a push to protect 30% of land and sea for nature by the end of this decade.
What to expect from COP15
In recent years, the global climate crisis has made more headlines than biodiversity. Yet both are inextricably linked.
Deforestation reduces the planet’s carbon carrying capacity while simultaneously destroying habitats. Erratic weather patterns, fires and floods—caused or exacerbated by climate change—erode ecosystem integrity.
As ecosystems break down, the natural barriers separating people from zoonotic diseases are reduced, with devastating consequences, as the COVID pandemic shows.
Unlike the UN climate process, which has a clear target to limit greenhouse gas emissions to 2℃, the biodiversity convention and its COPs have so far lacked a clear goal.
