Valuing reductions in the risk of death in benefit-cost analyses of environment- and climate-health actions.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Economic evaluation is key for efficient allocation of resources in health and related sectors. Actions addressing environmental risk factors and climate change can avert millions of deaths annually, yet valuing reductions in the risk of dying is challenging in benefit-cost analyses. We developed an interim statistical protocol to estimate the value per statistical life for World Health Organization (WHO) Member States, building on the 2019 benefit-cost analysis reference case and latest evidence. Using gross national income per capita based on purchasing power parity, we calculated national estimates for 2024 and projected values to 2100. We aggregated these estimates to produce global, regional and country income group averages, and additional sets for sensitivity and scenario analyses, including for alternative climate change scenarios. Our estimates cover 93.8% (182/194) of Member States, representing 98.4% (7.99 billion/8.12 billion) of the global population. The global average value per statistical life in 2024 was 3.76 million international dollars. By 2100, the global average is projected to increase by 159.8% to 9.77 million international dollars. These estimates provide a basis for valuing expected deaths averted by environment- and climate-health interventions, promoting comparability across analyses. Limitations include reliance on extrapolated values and uncertainty in income projections. More research, especially in low- and middle-income countries, is needed. Because value per statistical life estimates depend on income, analysts must supplement benefit-cost analysis with distributional analyses of benefits and costs across populations. Until WHO updates its recommended methods, these interim estimates offer a pragmatic tool for policy analysis.
