Here we use an optimization model to map out near-optimal energy system designs for 2050, focusing on the planning flexibility of individual regions while maintaining overall system robustness against different weather years, cost assumptions and land-use limitations. Our results reveal extensive flexibility at a regional level, where only few technologies (solar around the Adriatic and wind on the British Isles and in Germany) cannot be substituted. National policymakers can influence renewable energy export and hydrogen strategies significantly, provided they coordinate this with the remaining European system. However, stronger commitment to solar in southern Europe and Germany unlocks more design options for Europe overall. These results on regional trade-offs facilitate more meaningful policy discussions that are crucial in the transition to a sustainable energy system. Transitioning to a net-zero future requires several energy-related interventions by a variety of actors across scales. Modelling results now show that, considering critical trade-offs and uncertainties, there is significant spatial flexibility in how the European energy system can be designed to achieve carbon neutrality.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 6","pages":"629-641"},"PeriodicalIF":27.1,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122741","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, balancing high catalytic activity with selectivity is challenging because the complex interactions among intermediates across various active sites can trigger competing reactions. To address this challenge, we introduce a catalytic shunt strategy that redirects intermediates in a multifunctional catalytic system to guide interdependent reaction pathways. The key to this catalytic shunt strategy is modulating the adsorption of the intermediates across different activity domains. By tuning Mo–O coordination numbers of single atoms in a bifunctional catalyst, we achieve over 80% selectivity for aromatics and a carbon monoxide conversion surpassing 70%, with aromatics yields of over 40%. By absorbing the intermediates on the first activity domain, the shunt pathway prevents their participation in subsequent reactions, thereby boosting methane production with selectivity above 93% and carbon monoxide conversion exceeding 50%. This catalytic shunt strategy also showcases versatility across other bifunctional systems for producing gasoline and light olefins. Overall, this study provides a viable approach for tackling the activity–selectivity trade-off in catalytic syngas conversion, removing a major barrier preventing its practical implementation. Catalytic syngas conversion is an essential part of sustainable chemical production but is hindered by the trade-off between conversion activity and product selectivity. Here the authors address this challenge by developing a catalytic shunt strategy.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 5","pages":"508-519"},"PeriodicalIF":27.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122748","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}

The data collected allow the analysis of MW patterns related to COVID-19 restriction measures at different stages of the pandemic and enable the analysis of the sustainability of MW management. Our model estimates identify city-specific disposal optimization strategies for sustainable MW management. The dataset and the model presented here can support more in-depth research on MW management and aid policy makers dealing with the impacts of MW.

However, neither the working principle nor the technical route of combining non-reciprocal heat transfer with solid-state caloric cooling system is clear. Here we establish a framework for the development of non-reciprocal heat-transfer-enabled solid-state elastocaloric devices. We first illustrate theoretically that the thermal rectification ratio of non-reciprocal heat transfer unit is strongly correlated with the elastocaloric cooling performance. We further build an all-solid-state elastocaloric cooler prototype incorporated with a meta-material designed non-reciprocal heat transfer unit for efficient heat transfer and stable operations. With a thermal rectification ratio of 6.5, the cooler exhibits cooling power of 174.8 mW corresponding to a cooling heat flux of 242.8 mW cm−2. The cooler with non-reciprocal heat transfer units survives a long device-level operational fatigue life of over 2 million cycles without failure under the buckling-resistant compressive loading. Our work suggests new space for the design of next-generation cooling systems embracing sustainability. Elastocaloric cooling has emerged as an eco-friendly technology with low greenhouse gas emissions and high energy efficiency. Here the all-solid-state elastocaloric cooler shows a long operational life of over 2 million cycles.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 6","pages":"651-660"},"PeriodicalIF":27.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122944","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, this limited focus is insufficient in responding to the urgency, complexity and scale of the problem. Therefore, the scientific community increasingly calls for a systemic focus on plastic pollution, especially with respect to designing effective policy interventions. Extant literature has documented examples of science-based policy, showing that systems tools have successfully informed policies targeting plastic pollution. With a potentially first, global plastics treaty currently under negotiations, we analyse the way in which systems-based techniques are used in literature to generate evidence regarding plastic pollution and to inform policy processes. We systematically select 324 publications from the systems-based plastic pollution literature and analyse trends, patterns and context in which systems analysis tools are used. We find that the application of these tools is limited and still highly focused on the downstream impacts of plastics. Thus, we make two key recommendations for harnessing systems analysis techniques to strengthen the efforts at developing an ambitious, science-based treaty: the employment of an emitter perspective and supporting a just transition through systems literature. Plastics pollution has intertwined environmental, economic and social consequences calling for holistic solutions that require systems analysis. This study evaluates how and to what extent systems analysis tools are used in research on plastic pollution to support policy design.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 6","pages":"714-723"},"PeriodicalIF":27.1,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122946","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}

To enhance this understanding, we investigate the consequences of converting agricultural fields to solar photovoltaic installations, which we refer to as ‘agrisolar’ co-location. We present a food, energy, water and economic impact analysis of agricultural output offset by agrisolar co-location for 925 arrays (2.53 GWp covering 3,930 ha) spanning the California Central Valley. We find that agrisolar co-location displaces food production but increases economic security and water sustainability for farmers. Given the unprecedented pace of solar PV expansion globally, these results highlight the need for a deeper understanding of the multifaceted outcomes of agricultural and solar PV co-location decisions. This analysis looks at the impacts and outcomes from installing solar arrays on agricultural land, finding that these ‘agrisolar’ projects can displace food production but simultaneously provide economic security and offset water use.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 6","pages":"702-713"},"PeriodicalIF":27.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41893-025-01546-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122945","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}
