From Farm to Flavor: Carbon and Biodiversity Footprint of the Global Spice Market.
Article in Environmental science & technology, 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
Agriculture generates roughly one-third of global greenhouse gas (GHG) emissions and is the primary driver of biodiversity loss, underscoring the need to assess the environmental impact of all crops. However, the spice sector has received little attention, with only a few life cycle assessment (LCA) studies available. This study evaluates the carbon and biodiversity footprint of the global spice sector and situates the sector within the broader agricultural system. Climate impacts were quantified using the IPCC GWP100a method, while biodiversity impacts were assessed using LC-IMPACT and a land-use-induced biodiversity assessment method (the high-resolution land use intensities and fragmentation method, LUIF). Indirect drivers of species loss were found to be significant, highlighting the importance of biodiversity assessment beyond only land-use-induced impacts. To capture these effects more comprehensively, the LUIF method was integrated into the LC-IMPACT framework. Results indicate that the global spice sector emits between 41.4 and 64.8 Mt CO
