The impact of circular economy initiatives on urban air quality in the United States.
Article in Scientific reports, 2025. 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 study attempts to establish a connection between circular economy practices and urban air pollution in the United States, utilizing panel data from fifty states from 2009 to 2022. Given the poor state of air quality and its ominous threat to public health and environmental sustainability, the present study aims to provide empirical evidence on the effectiveness of circular economy methods in reducing harmful air pollutants. Applying the GMM estimator to the regression analysis reveals a significant positive relationship between high recycling rates and reduced air pollution levels. An Environmental Kuznets Curve has also been depicted by this study-a postulation showing that although per capita income may be increasing to start with higher pollution levels, at high-income levels it could further lead to improving air quality. These findings demonstrate the significant impact of population density on pollution levels, highlighting some of the challenges faced by metropolitan regions. The article underscores the significance of incorporating circular economy approaches into urban policy frameworks and offers fresh perspectives on guiding sustainable urban development processes.
