Water, air pollution and carbon footprints of conspicuous/luxury consumption in India
ECOLOGICAL ECONOMICS(2024)
摘要
The literature on the environmental impacts of household consumption in India focuses on carbon and ecological footprints of income groups. This article connects conspicuous/luxury (C/L) consumption in India to its local, regional and global environmental impacts. We evaluate carbon dioxide (CO2), water, and particulate matter (PM2.5) footprints of consumption disaggregated into food -basic, nonfood -basic, and C/L consumption across expenditure deciles. We find that all three footprints rise, but at different rates, with increasing expenditure. Notably, CO2 and PM2.5 intensities of C/L consumption increase with income, unlike all other intensities of consumption. However, in all three footprints, there is a disproportionate rise in the top decile, which is driven by C/L consumption expenditure more than the pollution intensity of C/L consumption. These results imply that demand reduction measures in C/L consumption could have broad -based and deep environmental benefits, while pollutant -specific mitigation policies may face trade-offs with other environmental impacts. There is a need for further research on connecting local and regional environmental footprints with the actual impacts, to better understand the relationships between conspicuous/luxury consumption and multi -dimensional environmental impacts in developing countries context.
