Nature-positive cities need a framework that survives the budget meeting
OECD’s 2026 Nature-Positive Cities paper moves biodiversity from a greening aspiration toward planning, investment, monitoring and trade-off management.
Signal
The paper identifies recurring barriers including competing urban priorities, limited technical guidance, constrained finance and weak monitoring, then proposes an integrated framework spanning biodiversity, climate, wellbeing and economic objectives.
Why it matters
Urban nature competes for land and money. A credible nature-positive city model therefore has to work where priorities collide, not only in renderings where every objective fits comfortably together.
Boundary
The OECD framework is policy guidance and synthesis. It does not certify any city as nature-positive or establish that adopting the framework alone will reverse biodiversity loss.
