Does economic growth reduce pollution?

The research examines the drivers of pollution reduction in the US, specifically distinguishing between automatic effects of income growth on consumer preferences and indirect effects from regulations and prices. Using Environmental Engel Curves (EECs) for particulate matter (PM10), the authors find that while richer households consume less pollution-intensive mixes of goods, this 'automatic' preference effect accounts for only half of the consumption-related pollution reduction; the other half is attributed to economy-wide changes like regulations. Overall, the largest contributor to US pollution cleanup is identified as changes in production technology.

• In the United States, GDP per capita nearly doubled over 30 years while manufacturing emissions decreased significantly: ozone by 33%, nitrogen dioxide by 60%, sulfur dioxide by 81%, and carbon monoxide by 84%.
• The authors argue that Environmental Kuznets curves (EKCs), which show pollution decreasing as national income rises in rich countries, are merely correlations and do not prove that income growth directly causes environmental improvement.
• Analysis of Environmental Engel Curves (EECs) for particulate matter (PM10) reveals that richer households consume less pollution-intensive mixes of goods and services, but they are still responsible for more total pollution than poorer households.
• The reduction in US pollution resulting from shifts in household consumption is split equally: approximately 50% is due to the direct effect of income growth on consumer preferences, and 50% is due to indirect economy-wide changes such as prices and regulations.
• While consumption shifts are important, the primary driver of the overall pollution cleanup in the United States has been improvements in production technology.
