However, deep detritiation remains a major challenge due to the nearly indistinguishable physicochemical properties among water isotopologues. Here we present an efficient hydrogen isotope separation process based on catalytic proton exchange. The unique catalysis-promoted proton-transfer pathway found in a metal–organic framework (MIL-101(Cr)) significantly lowers the isotope exchange energy barrier to a previously unachieved level. Incorporating MIL-101(Cr) into a water distillation (WD) system enables a solid–liquid–gas triphasic mass transfer that overcomes the thermodynamic constraints of traditional WD, which relies on a liquid–gas biphasic isotope exchange. The height equivalent to the theoretical plate of the established WD prototype fell by half compared to the existing WD systems, thus increasing the separation efficiency by over four orders of magnitude in a 10-m distillation tower. This work offers an industrially viable and scalable option for cleaning up tritiated water. It is extremely difficult to separate tritium from radioactively contaminated water. Here the authors introduce catalytic hydrogen isotope exchange to water distillation, realizing excellent detritiation performance.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 5","pages":"553-561"},"PeriodicalIF":27.1,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such impacts can be assessed by environmental sustainability indices; however, limitations in current indicators necessitate the development of more robust and standardized crop-specific environmental sustainability indices. Here we developed the crop environmental sustainability index (PLANTdex), a spatially explicit index (5 arcmin resolution) quantifying crop production’s environmental impacts. PLANTdex includes globally standardized indicators of environmental impacts assessing water stress and biodiversity loss via five emissions pathways: greenhouse gas emissions, water consumption, land occupation, and nitrogen and phosphorus fertilizer application. We applied PLANTdex to 16 crops, revealing high variability across production system efficiencies, crop types and local context environmental sensitivities. Globally and nationally, no clear correlation emerged between PLANTdex scores and crop production, but stronger correlations were evident at finer spatial scales and for individual crops. Sugar cane showed the strongest negative correlation (low impacts in high-production areas), while oil palm had the strongest positive correlation (high impacts in high-production areas), highlighting the importance of sub-national, crop-specific assessments. PLANTdex’s spatial resolution and crop specificity make it valuable for initiatives such as the Taskforce on Nature-related Financial Disclosures and corporate sustainability strategies. Environmental impacts of agriculture can be difficult to assess due to limitations in current environmental sustainability indicators of crop production. This study develops a robust crop-specific environmental sustainability index that helps assess corporate sustainability strategies and policy.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 4","pages":"396-410"},"PeriodicalIF":27.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41893-025-01528-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the actual environmental mitigation potential of this strategy depends on future technological advancements and contextual factors, which remain uncertain. Here we compare five conventional bioresidue valorization pathways with insect farming, microbial conversion and protein extraction by simulating their life-cycle assessment across 8,820 combinations of future process efficiencies, 9 food and energy systems scenarios and 11 representative bioresidues across France. Overall, processing bioresidues into novel ingredients is competitive only in certain conditions. These include access to decarbonized energy, substantial technological advancements and scenarios where novel ingredients replace meat rather than animal feed. The microbial conversion of woody residues, manure and sludge into feed will constitute the more sustainable valorization strategy only in contexts where current demand for animal-based food is maintained. However, the sustainability of this scenario must still be further appraised in terms of scaling these systems to a broader level. Efforts to curb environmental effects of food systems have led to the development of ‘waste-to-nutrition’ pathways that process bioresidues into food and feed products such as microbial proteins and insects. This paper examines the environmental mitigation potential of such pathways across France.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 4","pages":"385-395"},"PeriodicalIF":27.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, several challenges remain to be overcome, such as large photovoltage loss, poor stability and scalable fabrication in ambient air, which hinder the commercialization of this technology. Here we incorporate a reductive methylhydrazinium cation into WBG perovskites, which not only reduces defect density but also suppresses iodide oxidation and halide demixing, enabling scalable fabrication of efficient and stable WBG solar cells and modules in ambient air. Remarkably, the champion WBG perovskite solar cells achieve a power conversion efficiency (PCE) of 23.3% with an open-circuit voltage of 1.28 V, corresponding to a record low voltage loss of 0.37 V. The WBG mini modules deliver a stabilized PCE of 19.8% with an aperture area of 25 cm2. The mini modules can keep 94% of the initial PCE after 700 hours of operation under continuous light soaking at 1-sun illumination at 55 ± 5 °C. This work suggests a viable route to the sustainable harvesting of solar energy. Wide-bandgap perovskites are critical to tandem solar cells for maximized solar energy capture and efficiency, but their stability remains a major issue. Here, by introducing reductive cations, the authors realize scalable fabrication of large-area solar cells in ambient conditions with good performance.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 4","pages":"456-463"},"PeriodicalIF":27.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
