Are there gender differences in household carbon footprints? Evidence from Spain
研究利用西班牙家庭数据，通过多区域投入产出模型计算碳足迹，发现男性主导的家庭碳足迹更高，且消费模式存在性别差异，为减排政策提供参考。
Identifying the main drivers of the household carbon footprint (HCF) is a priority to reduce greenhouse gas emissions and move towards a more sustainable economy. Among the multiple factors that explain the HCF, some previous research has confirmed the relevance of gender. In this paper, we calculate the HCF of individual Spanish households using an environmentally extended multi-regional input-output model (EEMRIO) that quantifies the emissions embedded in the supply chain of goods and services that households consume. We assess the differences in consumption and emissions patterns, measuring the gender effect by a new variable, the female share of the household. This represents a remarkable improvement over previous literature that used simpler approaches. Moreover, we assess the partial effect of gender on HCF using multivariate regressions for total and sectoral emissions. Our results show that households with a majority of men have a higher HCF and carbon intensity. Even when controlling for economic, sociodemographic, and regional factors there are differences in the sectoral emissions according to gender. Female households spend more (and generate more emissions) on housing and food products, while male households show that pattern for restaurants and transport. These results can help orientate environmental campaigns and demand-side mitigation policies.
