Key Takeaways
- 6.3 million deaths were attributable to ambient (outdoor) air pollution globally in 2019 (WHO estimates)
- 7.2 million deaths were attributable to household air pollution (from solid fuels and inefficient stoves) globally in 2019 (WHO estimates)
- 6.1 billion people use at least basic sanitation services (WHO/UNICEF JMP headline for coverage; contrasts with safely managed)
- 2°C is the upper-bound warming target set by the Paris Agreement, aiming to limit warming to well below 2°C and pursue efforts for 1.5°C
- 66% reduction in CO2 emissions by 2030 from 2010 levels is required for the 1.5°C-consistent pathway (IPCC-aligned carbon budget logic summarized in UNFCCC/LIFE requirements)
- 9% of global land is covered by forests lost since 1990 (forest area change context in FAO Global Forest Resources Assessment)
- 10.3 million km² of land is protected worldwide as terrestrial protected areas (WDPA/UNEP-WCMC summary figure)
- 17% of terrestrial and inland water areas were protected globally by 2023 (Protected Planet/UNEP-WCMC reporting)
- 2 billion people lack access to safely managed drinking water services (WHO/UNICEF JMP estimates for 2022)
- Up to 1.1% of global freshwater withdrawals are used for industrial purposes in OECD countries (OECD data table on freshwater withdrawals by sector)
- 31% of global freshwater withdrawals are for agriculture (FAO/AQUASTAT and UN water sector splits summarized in UN-Water resources)
- Only 9% of plastic waste is recycled globally, with 19% captured for recycling and much more mismanaged (OECD Global Plastics Outlook)
- 25% of global municipal solid waste is organic and biodegradable (UNEP waste composition statement in municipal waste materials)
- 12% of municipal solid waste in OECD countries is recycled and composted vs. higher in select jurisdictions (UNEP/OECD waste management statistical overview)
- 12.6 million people experience water scarcity risk from drought annually in the last decade in OECD projections (OECD water scarcity assessments)
Air pollution, biodiversity loss, and water stress are driving major health and economic costs while climate action remains insufficient.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
