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. Our study offers actionable insights for policymakers and stakeholders, informing the transition toward sustainable pest control practices aligned with European Green Deal objectives.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"58 ","pages":"Pages 237-250"},"PeriodicalIF":10.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570214","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}

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.

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.
