Summary

This article analyzes the trade-offs associated with large-scale carbon dioxide removal (CDR) as part of economy-wide net-zero emissions strategies. While reducing fossil fuel combustion provides climate and air quality-related public health benefits, the deployment of CDR technologies may introduce new public health, economic, and environmental trade-offs. The article examines how different CDR approaches (such as direct air capture, bioenergy with carbon capture, and afforestation) interact with air pollutant emissions, economic costs, and climate outcomes, highlighting that the net benefits depend heavily on how CDR is implemented and scaled.

Fossil fuel combustion is the principal source of both greenhouse gas (GHG) emissions and criteria air pollutants such as particulate matter (PM2.5) and ozone (O3).

In the U.S., air pollution causes 100,000–200,000 premature deaths annually, valued at $0.9–1.8 trillion USD2020 based on the Environmental Protection Agency (EPA) $9.25 million USD2020 value of statistical life.

Economy-wide efforts to achieve net-zero emissions offer climate and air quality-related public health benefits from reducing fossil fuel combustion. However, carbon dioxide removal (CDR) may be necessary to address residual emissions.
