Cop17 at a glance: everything you need to know about the UN’s nature summit

Cop17, the UN's biodiversity summit in Yerevan, Armenia this month, marks the first formal assessment of progress against the 23 targets agreed at Cop15 in 2022. Those targets were hailed as ambitious – a once-in-a-decade commitment to reverse nature loss amid scientific consensus that Earth is experiencing extinction rates unseen since the dinosaurs disappeared.

The stakes are real but the track record is thin. Most governments entered Cop15 without domestic legislation to enforce the targets, and corporate accountability mechanisms remain fragmented. Biodiversity metrics lag far behind carbon reporting in maturity: there is no agreed global standard equivalent to the GHG Protocol or SBTi for nature-related financial disclosure, though the Task Force on Nature-related Financial Disclosures (TNFD) is filling that gap.

What matters at Cop17 is whether governments will commit to legally binding implementation mechanisms, and whether they will anchor biodiversity targets to procurement, supply chain due diligence, and financial institution lending criteria. Without those levers, targets remain aspirational.

The biodiversity summit also exposes a strategic gap: most large organisations treat nature risk and climate risk as separate workstreams, when they are deeply interdependent. Deforestation, water stress, and soil degradation are material to supply chain resilience, yet biodiversity rarely appears in materiality assessments alongside climate and governance.

Yerevan will reveal whether governments intend Cop15's commitments as enforceable law or symbolic cover.
