The Community-Environment-Health Nexus: Connecting Community-Led Climate Action to Health Co-Benefits.
Article in International journal of environmental research and public health, 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
backgroundClimate action initiatives primarily target environmental outcomes, but their potential for health co-benefits through green and blue space contact remains understudied. Understanding these secondary outcomes could inform dual-purpose programming addressing climate and health challenges.
methodsThis retrospective analysis examined 32 community-led climate action projects funded through Edinburgh Communities Climate Action Network (ECCAN) and their GreenLight programme (2024-2025). Projects spanned energy, transport, food, circular economy, and green space themes, with no formal health evaluation framework. Data were extracted from final reports covering 3195 direct participants.
resultsDespite health not being a primary objective, 21 of 32 projects (66%) reported secondary health and wellbeing outcomes. Projects involving direct nature contact showed the strongest co-benefits: nine of ten high-nature-contact projects reported health benefits, compared to two of eight low-nature-contact projects. Notable outcomes included 94% of participants reporting increased willingness to engage in future community activities and 76% reporting mental wellbeing improvement following community garden workshops. Blue space engagement demonstrated particular significance for mental health and social cohesion.
conclusionsGreen and blue space engagement in climate action projects consistently produces secondary health outcomes. We propose the Community-Environment-Health Nexus (CEHN) framework to understand how community-led environmental action generates synergistic health co-benefits.
