Research at this intersection is, however, notably lacking. This review paper seeks to understand the current state of both environmental and economics research with respect to different agricultural crop production methods (orchard, vegetable, open field crop, etc.), regions, and the types of precision agriculture technologies applied in each context. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis method was used to answer three review questions to address a targeted subset of precision agriculture technologies relevant to field crop production, from both environmental and economic perspectives and at the global level. Fertilizer production/use and associated field-level emissions are the leading cause of environmental impacts in many life cycle impact categories, and energy and pesticide use also contribute significantly. For most environmental impact categories, the utilization of precision agriculture practices reduced these impacts as compared to conventional practices. Many precision agriculture technologies focus on nitrogen management, namely variable rate application of nutrients, but disproportionately in the context of high value crops. There is evidence that supports the notion that variable rate fertilization management leads to reduction in many but not necessarily all environmental impacts. Some studies reported no, or limited economic benefits associated with precision agriculture technologies, however overall results suggest that precision agriculture utilization delivers economic benefits either via cost savings, input savings, and/or increases to yield, margin, or profits. Variable rate technology is highlighted as a promising subset of precision agriculture technologies in terms of environmental impact reductions and economic benefits.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"52 ","pages":"Pages 347-362"},"PeriodicalIF":10.9,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654310","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}

Previous studies have focused on either live-biomass carbon stocks in plantation forests or anthropogenic carbon stocks in man-made objects. For a comprehensive nature-based climate solution, an analytical framework, dataset, and scenario setup for modeling the interrelationship between timber supply and demand are required. This study developed an interlinked material flow analysis model in which the timber demand for wooden houses is connected with timber supply from managed plantation forestry. We demonstrate the model by quantifying both live-biomass and anthropogenic carbon stocks and their potentials in Japan. We compared multiple scenario-runs of the model for wooden house demands estimated by population change with varying combinations of house types, structures, and lifespans. Our results show that carbon stocks will reach a maximum amount of 1.1 billion t-C by 2050 in a scenario of high demand for wooden detached houses with lifespan extensions. On the other hand, we also found that the aging of plantation forests and their reduced carbon-stocking capacities appear inevitable in any scenario owing to the limited demand for timber. Notably, despite the widely different settings of the various scenarios, our results exhibited narrow variances in future potential carbon storage in Japan. This can be explained by the unique population characteristics and building demographics of Japan. These counterintuitive findings highlight the need for interrelated modeling of the forestry and construction sectors.

Since the number of products in a company's portfolio can include thousands of different products, there is an urgent need for faster ways to estimate impact hotspots and to ultimately obtain adequate inventories. In recent years machine learning (ML) has emerged as a promising strategy to tackle cost- and resource-prohibitive accounting practices. However, to be practically applied, new concepts must not only be built on a large data basis allowing to predict diverse products with varying reference flows, but they must also ensure high data quality by reflecting different types of uncertainties. Therefore, in this publication we pursued three distinct objectives: building on digitized environmental product declarations, we first predicted life cycle environmental impacts with artificial neural networks (ANN) and second performed an in-depth characterization of uncertainty and sensitivity analysis methods to identify which methods can analyze what uncertainty types. Based on this analysis, we chose residual Gaussian Process Regression (rGPR) as suitable uncertainty analysis method and employed, in a third step, an advanced ANN-rGPR hybrid model to quantify associated model uncertainties. While our final model derived high prediction performances and low model uncertainties across a large impact range, we conclude that the practical use of ML-based predictions remains limited, as long as reported product disclosures lack critical modeling specifications. However, if future reporting requirements comprehensively demanded such information, ML models could conceptually incorporate this information, thereby not only substantially improving the data quality but also the feasibility of practical implementation.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"52 ","pages":""},"PeriodicalIF":10.9,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142704615","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}

To support these efforts, this article aims to review the LCA practices across various sources in order to identify where key differences in assumptions, methodological approaches, and data selection occur in relevant LCA topics. In addition to this primary objective, we highlight certain practices that could serve as starting points for ongoing harmonization attempts, pointing out topics where it is challenging to do so. Our results showed that cradle-to-grave system boundary is the most commonly adopted in vehicle and traction battery LCAs, with maintenance and capital goods often excluded. The distance-based functional unit is dominant. Choices in Life Cycle Inventory (LCI) showed the greatest diversity and need for harmonization.

Systematic uncertainty propagation is rare in interpretations, with sensitivity analyses typically focusing on energy consumption, total mileage, and battery recycling rates.

The existing literature focuses predominantly on technological strategies such as low-carbon materials. This prompts the question: Can technological strategies alone drive the decarbonization of buildings, or are non-technological strategies also essential? Although recent research considers the benefits of the latter, studies assessing the potential of non-technological strategies for decarbonization of buildings are lacking because of the challenges involved in evaluating the indirect impacts and potential trade-offs associated with these strategies such as their ripple effects on mobility. This study pioneers a comparative assessment to evaluate the environmental mitigation potential of non-technological strategies (adaptation, a subset of the sharing economy, and behavioral changes) against technological strategies (low-carbon materials, retrofitting, and recycled materials) to ascertain the effectiveness of non-technological approaches. Through life cycle assessment, this study extends beyond solely evaluating the GHG reduction potential to assess the overall environmental mitigation capacity. A single-family house in Montreal was used as a reference scenario. With significant mitigation potential observed from a non-technological perspective, the results robustly reveal that the adaptation scenario surpasses all scenarios, including retrofitting, which is the primary mitigation strategy for existing buildings, by up to 50 % and 41 % at the midpoint and damage levels, respectively. Furthermore, the adaptation scenario potentially provides sufficiency by saving considerable amounts of material and energy, thereby alleviating the environmental impact of the production and use stages by up to 27 % and 15 %, respectively. This study also evaluates the combined effects of adaptation and retrofitting for existing buildings, revealing by up to 8 % greater environmental benefits at the midpoint and damage levels than in the adaptation scenario individually. These results highlight the potential of non-technological strategies that are currently overlooked in the building sector. However, their implementation requires fewer resources and less energy than technological changes. Therefore, further investigation is warranted to explore how adopting these strategies, along with technological ones, is advantageous.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"52 ","pages":"Pages 268-282"},"PeriodicalIF":10.9,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654245","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}

Further analysis reveals that production structure would be the primary driver of mitigating transfers. Additionally, carbon intensity in both power and non-power sectors can also contribute to mitigation. This is exemplified by the dampening effect exerted by carbon intensity of power sector on China's TIC during 2014–2019 (−8.5 Mt).
