Reducing the contribution of the power sector to ground-level ozone pollution : an assessment of time-differentiated pricing of nitrogen oxide emissions
Nitrogen oxide (NOx) is a prevalent air pollutant across the United States and a requisite precursor for tropospheric (ground-level) ozone formation. Both pollutants significantly impact human health and welfare, so National Ambient Air Quality Standards (NAAQS) have been established for each. As …
