Using a carbon market-like tool to control air pollution can help developing countries such as India, where the standard approach of limiting the emissions with policymaking is falling short, a new study has found.

Air pollution is one of the most pressing health issues in India, where the country¡¯s 1.4 billion people breathe air exceeding the World Health Organization¡¯s guidelines for particulate matter.

Those are particles finer than human hair that can cause severe health issues, such as respiratory infections and lung cancer.
