Abstract

As a major driver of global production, household consumption warrants increased attention due to its potential for decarbonization. This study systematically reviews 4647 journal papers to uncover evolving research themes and regional disparities in household carbon emissions research. We identified a marked increase in publications after 2015 and, using natural language processing, defined 7 distinct research clusters. While earlier studies focused primarily on energy consumption, more recent research has broadened to encompass a range of topics, including food systems, supply-chain emissions, and renewable energy. Our regional analysis reveals varied levels of research engagement across countries. The Global South is increasingly involved, focusing on cooking facilities and household energy use, whereas Europe emphasizes policy-oriented mitigation. North America, led by the United States, focuses on transportation emissions and residential energy-efficiency modeling, while Asian countries examine urban-rural disparities and household inequality. Drawing on these thematic and geographical insights, this study identifies current knowledge gaps, such as the need for cross-regional comparisons and supply chain integration. These insights offer actionable directions to promote sustainable consumption practices and support global climate goals.
用机器学习追踪家庭碳排放研究的演变
作为全球生产的主要驱动力,家庭消费由于其脱碳的潜力而值得更多关注。本研究系统回顾了4647篇期刊论文,揭示了家庭碳排放研究的发展主题和区域差异。我们确定了2015年后出版物的显著增加,并使用自然语言处理定义了7个不同的研究集群。虽然早期的研究主要集中在能源消耗上,但最近的研究已经扩大到涵盖一系列主题,包括食品系统、供应链排放和可再生能源。我们的区域分析显示,各国的研究参与程度各不相同。全球南方国家越来越多地参与其中,重点关注烹饪设施和家庭能源使用,而欧洲则强调以政策为导向的缓解措施。以美国为首的北美侧重于交通排放和住宅能源效率模型,而亚洲国家则研究城乡差距和家庭不平等。根据这些专题和地理见解,本研究确定了当前的知识差距,例如跨区域比较和供应链整合的需求。这些见解为促进可持续消费实践和支持全球气候目标提供了可行的方向。

期刊介绍: Environmental Impact Assessment Review is an interdisciplinary journal that serves a global audience of practitioners, policymakers, and academics involved in assessing the environmental impact of policies, projects, processes, and products. The journal focuses on innovative theory and practice in environmental impact assessment (EIA). Papers are expected to present innovative ideas, be topical, and coherent. The journal emphasizes concepts, methods, techniques, approaches, and systems related to EIA theory and practice.
