This report provides an overview of methodologies to evaluate the effectiveness of policy instruments for biodiversity, covering impact evaluation, cost-effectiveness analysis, and other approaches. It then provides an inventory of biodiversity-relevant impact evaluation studies, across both terrestrial and marine ecosystems. The report concludes with lessons learned, policy insights, and suggestions for further work.
This report provides investment potential estimates across six key sectors (waste, renewable energy, public transportation, water, electric vehicles, and green buildings). Sector-specific investment potentials are estimated at the global and regional levels. The report also addresses urban resilience, financing solutions, and includes six deep dives into specific cities – one from each region – representing various sizes and stages of development:
