Here we report a one-step dehydration–condensation method for the economical and green preparation of GR2Ms on a gram scale from biomass at room temperature under atmospheric pressure using only concentrated sulfuric acid. This protocol has been applied successfully to various types of biomass and carbohydrates, delivering a 33% mass yield of GR2M product. The properties of the product are consistent with those of classical reduced graphene oxide (RGO), with the twist that it does not need to be produced from graphite minerals. The mild reaction conditions substantially reduce the energy input, while providing a facile platform for monitoring the kinetics of RGO nucleation and growth. Compared with conventional methods, a 98% reduction in energy consumption is achieved. Overall, the results of this research pave a new avenue to scalable and sustainable GR2M production. Reduced graphene oxide materials are of great interest in many fields, but current production methods are neither sustainable nor scalable. Here the authors report a method that enables the facile production of reduced graphene oxide from biomass at ambient temperature.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 12","pages":"1699-1708"},"PeriodicalIF":25.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845178","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, the presence of polyvinyl chloride (PVC) often complicates the co-upcycling processes, because chlorine (Cl) released from PVC can deactivate catalysts and enter final products. Moreover, existing plastic upcycling processes usually require harsh reaction conditions. Here we present a strategy enabling efficient co-upcycling of PVC and polypropylene (PP) at mild conditions. We use chlorine-resistant ionic liquids butylpyridinium chloride-aluminium chloride to dechlorinate PVC and simultaneously depolymerize the PP–PVC mixture into Cl-free liquid hydrocarbons, with the co-production of hydrogen chloride (HCl) as byproduct. This conversion approach operates at room temperature without the use of external hydrogen or noble metal catalysts. The Cl-free liquid hydrocarbon yield is up to 97.4 wt% of C and H in the feed PP–PVC mixture. This work can incentivize further technical development in plastic upcycling and improve the sustainability of plastic waste management. Upcycling of mixed plastics containing polyvinyl chloride is challenging. This study reports a strategy to co-upcycle polyvinyl chloride with polypropylene to obtain dechlorinated liquid hydrocarbons at high yields at room temperature without the use of external hydrogen or noble metal catalysts.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 12","pages":"1691-1698"},"PeriodicalIF":25.7,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845087","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}

Governments can, however, try to increase public support for it by adjusting how the revenues raised by the carbon price are used. In a fully incentivized experiment with a large representative sample of the German population, we compare voter support for five different carbon pricing schemes. We show that uniform carbon dividends (equal per capita transfers to all citizens) receive substantially more support than a carbon dividend that favours poorer people, than earmarking revenues for climate projects and especially than using revenues for the general government budget. Among the uniform carbon dividend schemes, a climate premium that pays a fixed upfront transfer equal to the expected carbon revenues receives more support than a carbon dividend scheme where the size of the transfer is determined ex post based on the actual revenues. Furthermore, we show that participants and experts underestimate public support for carbon pricing. These findings suggest that policies for sustainable development gain more support when affected voters are uniformly compensated for the costs imposed on them. In addition, the paper highlights the importance of incentivized experiments in studying public support for such policies. How revenues from a carbon price are returned to society may affect public support for the adoption of such a policy. In an experiment with a large sample of the German population, public support for a carbon price is assessed for five different revenue recycling schemes.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 12","pages":"1633-1641"},"PeriodicalIF":25.7,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01466-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845135","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}

These disputes impact national and global environmental policy, but there is limited knowledge about outcomes for pro- and anti-regulatory plaintiffs or which areas of environmental policy are focused on by different plaintiffs. Drawing on 25,775 environmental civil suits and 4,142 judicial decisions filed in federal district courts between 1988 and 2022, we show that pro-regulatory plaintiffs tend to have a higher win rate than anti-regulatory ones, that federal enforcement litigation focuses overwhelmingly on pollution and waste-related conflicts, that environmental advocacy groups focus heavily on conservation-related conflicts and that climate and environmental justice-related themes are rarely discussed in environmental legal decisions. The inequality in legal advocacy that we document may help to explain areas of strength and weakness in US environmental policy, with implications for environmental justice and global sustainability. Environmental law is shaped by litigation outcomes as much as by legislation. This study examines nearly 30,000 civil suits and court decisions over 34 years to help reveal their influence on the legal and environmental landscapes of the United States.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 11","pages":"1469-1480"},"PeriodicalIF":25.7,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01456-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672797","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}
