Poorer households in India are bearing a disproportional impact from pollution caused by others, a new study by Yale School of the Environment Associate Professor of Energy Systems Narasimha Rao has found.
The study, published in the journal Nature Sustainability
, is the first to analyze and review how different households contribute to air pollution, as well as the impact of the pollution on different households by income levels.
“Low-income groups, despite not producing a lot of air pollution indirectly because they don't consume much, are facing a disproportionate impact of air pollution from other sources,’’ Rao says.
The study, “Household contributions to and impacts from air pollution in India,” was co-authored by Gregor Kiesewetter, Jihoon Min,
Shonali Pachauri, and Fabian Wagner of the International Institute for Applied Systems Analysis where Rao is also a senior research scholar.
