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.
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.
