Marginal Cost of Carbon Sequestration Using Straw-Based Biochar in Great Britain.
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
Achieving the net-zero target of the United Kingdom requires substantial greenhouse gas removal (GGR) in addition to emission reductions. Biochar, a stable carbon-rich material produced through biomass pyrolysis, is an established GGR method. Straw is abundantly available in the UK and presents a viable option for large-scale biochar production. However, uncertainties regarding its feasibility remain, particularly concerning costs, spatial constraints, and facility construction. Here, we use a spatial model integrated with life cycle assessment and technoeconomic analysis to estimate the marginal cost curve for net carbon sequestration through straw-based biochar production in Great Britain (GB). Our findings reveal that straw-based biochar production in GB can achieve 0.6-1.9% of the UK's 2050 carbon removal target at marginal costs below £75 per tCO
