Global implications of uncertainty in China's climate policy delivery.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The delivery of China's climate policy has substantial global implications, yet persistent gaps between policy targets and implementation raise concerns about policy credibility. This study presents a structured credibility assessment of 292 targets across 58 national climate and energy policies, including China's updated 2035 NDC. We apply a morphological scenario framework to examine interactions between policy uncertainty and socio-economic and technological drivers, embedding these scenarios in an integrated assessment model under two global contexts: one aligned with current NDCs and one consistent with global net-zero ambition. We find that timely or accelerated delivery of China's net-zero target could partially offset insufficient ambition elsewhere by mid-century. Full delivery by 2050 reduces global CO₂ emissions to 13 Gt, compared with 23 Gt without such policies. Policy delivery uncertainty alone could imply up to ~500 GtCO₂ difference in cumulative emissions by 2100 (~0.17 °C warming).
