In this article, we micro-simulate the impact at the border of a carbon tariff on food trade, modelling UK food imports from the European Union using a gravity model. In this exercise, we implement a Carbon Border Adjustment Mechanism, which charges for the difference in carbon emissions of a good between importer and exporter. Yearly country-level greenhouse gas emissions are calculated using a top-down life-cycle assessment approach known as environmentally-extended multi-regional input-output analysis. Results show that a British food Carbon Border Adjustment Mechanism would cut annual emissions imported from the European Union by around 25 % through trade reallocation. The findings indicate that carbon border regulation is an important tool for promoting more sustainable food systems.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"58 ","pages":"Pages 251-266"},"PeriodicalIF":10.9,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144580707","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}

As countries seek scalable climate solutions, understanding the viability of such approaches in developing nations is increasingly critical. This paper is the first to determine the environmental impacts and economic feasibility of building with biomass using timber, focusing on the residential housing sector in a developing country such as Malaysia. Four tropical hardwood species are considered: resak, keruing, sesenduk and rubber. The environmental assessment comprises 18 life cycle assessment impacts and the economic assessment focuses on life cycle costs. The system boundary includes all activities from cradle to grave, i.e. from timber production to house demolition. All timber species result in net-negative global warming potential (GWP), ranging from −473 to −736 kg CO₂ eq./t CO₂ removed without the credits for energy savings in the use stage relative to concrete houses dominant in Malaysia. With the credits, the savings in the emissions are around 30–60 % greater (−745 to −973 kg CO₂ eq./t CO₂ removed). Resak and rubber perform best overall, while sesenduk ranks lowest across most impacts. The life cycle costs are estimated at US$338–823/t CO₂ removed across the scenarios and timber types, with resak being the least and keruing the most expensive option. Assuming all houses are built from one type of timber could remove from 47 Mt CO₂ (sesenduk) to 98 Mt CO₂ (resak) over 50 years, reducing 4–8 % of the country's agricultural emissions annually at the cost from US$38 bn (rubber) to US$83 bn (keruing). Using an optimal combination of the four timber types would remove 89.12 Mt CO₂ over 50 years at a total cost of US$53.5 bn. However, in comparison with other bio-based NETs, building with biomass is the least sustainable option. Reforestation is the best alternative, removing 153–587 Mt CO₂ at a total cost of −US$10.2 bn (profit) to US$5.8 bn over 50 years, followed by bioenergy with carbon capture and storage (BECCS) with 840 Mt CO₂ and US$63.6 bn over 30 years and biochar with 248 Mt CO₂ and US$21.5 bn over 20 years. Utilising the country's available resources with an optimal mix of the four bio-NETs could remove 27.5 Mt CO₂ per year (9.5 % of Malaysia's annual emissions) at a cost of US$1.92 bn/yr. Over the lifetime of the NETs, this would amount to a total CO₂ removal of 930 Mt at a cost of US$56 bn.

To understand environmental implications of pesticide usage across farming systems and strategies, we quantify the environmental impacts of pest control for 160 farms across 10 European countries, applying a full life cycle perspective. We integrate emission estimates from pesticide field applications, environmental interventions from supply chain processes, and spatial variation in ecological pressure. Results reveal that farm-level impact performance is highly affected by the type of pest control agents applied. Copper-based fungicides were identified to drive the chemical footprint in terms of human toxicity and ecotoxicity impacts across conventional, integrated pest management (IPM), and organic pest control scenarios, associated with supply chain and field-level emissions. Almost all considered organic farming scenarios performed better than IPM or conventional farming with respect to their chemical footprint (i.e. human toxicity and ecotoxicity impacts), with similar impact profiles for IPM and conventional farming practices. Due to reported extensive use of copper-based fungicides, some IPM and organic farming scenarios showed high toxicity impacts, driving overall human health and ecosystem quality impact for these scenarios. Spatial analysis highlights that only a limited number of pesticides contributes to local potential exceedance of ecotoxicity pressure across catchments. Our findings emphasize the role of supply chain emissions, including diesel fuel used for agricultural machinery and pesticide production, as important contributors to life cycle impacts, including impacts on climate change and natural resources. We identified critical trade-offs between pest control strategies, such as reduced chemical footprints from avoiding synthetic pesticides versus increased resource use and greenhouse gas emissions in IPM and organic farming scenarios. We highlight the importance of designing pest control strategies that minimize environmental impacts while maintaining agricultural productivity.

This study assesses carbon dioxide (CO₂) utilization pathways in Thailand's cement industry for the production of urea, dimethyl ether (DME), and methanol by employing life cycle assessment, levelized cost analysis, and breakeven analysis under dynamic policy scenarios. At the midpoint level, urea and DME demonstrate favorable environmental profiles, with urea showing better performance in 16 out of 18 environmental indicators while DME exhibits advantages in 13 of the assessed categories. Methanol displays a more neutral profile with values close to zero across most categories. At endpoint level, all three CO₂ utilization pathways outperform their conventional fossil-based counterparts across multiple categories. Urea shows the highest CO₂ avoidance potential (3.47 kg CO₂ per kg of CO₂ utilized), which could potentially avoid emissions equivalent to 24 % of Thailand's total national emissions if all cement industry CO₂ were utilized, followed by DME (1.65 kg CO₂, 11 %) and methanol (0.77 kg CO₂, 5 %). The cost analysis reveals that levelized production costs are highest for DME at USD 1544 per tonne, followed by methanol at USD 824 per tonne, and urea at USD 476 per tonne; however, these are significantly higher than conventional production methods. Several factors can close the cost gap between CO₂-derived and conventional chemical production. Lower renewable electricity costs offer the most practical path to economic viability, as solar and wind energy prices have substantially decreased over the past decade, directly benefiting these electricity-intensive processes. Else, carbon credit support would be required ranging from USD 74/t-CO₂ for urea to USD 310/t-CO₂ for DME, with methanol requiring USD 216/t-CO₂. A strategic approach for Thailand would combine declining renewable electricity costs with international market opportunities that value low-carbon products.

We extend previous research by using a three-level analysis examining simultaneously resource retention options (RO), managerial practices, and business model value dimensions to understand how firms introduce circular economy practices in their business model to maximize resource value retention. Our study shows which 10 ROs are chosen by companies when they move to a circular business model and besides recycling and reducing, rethinking appears the most implemented RO. We identify 46 distinct CBMI managerial practices that companies implement across the three core business model dimensions—value proposition, value creation and delivery, and value capture. The analysis of the various combinations of RO and managerial practices in the different value dimensions of the business model implemented by the studied companies identifies five CBMI patterns, representing recurring combinations of practices that reshape business models towards circularity. Our results show that CBMI cannot be implemented as a one-size-fits-all solution and that firms must adopt a tailored approach depending on various aspects such as size, industry, consumer segment, as well as, resource availability and motivational drivers, by implementing circular practices across multiple business model dimensions while combining various ROs to enhance circularity.
