The NOx Budget Trading Program (NBP) is a market-based cap and trade program created to reduce emissions of nitrogen oxides (NOx) from power plants and other large combustion sources in the eastern United States. NOx is a prime ingredient in the formation of ground-level ozone, a pervasive air pollution problem in many areas in the East. The NBP was designed to reduce NOx emissions during the warm summer months, referred to as the ozone season, when ground-level ozone concentrations are highest. This report provides background on ozone formation and effects and evaluates progress under the NBP in 2006. The report examines reductions, reviews compliance results and market activity, and compares changes in emissions to changes in ozone concentrations.

The NBP, a Cap and Trade Program, Is Effectively Reducing Emissions across a Broad Region

There Have Been Improvements in Nonattainment Areas in the East since Implementation of the NBP

Ozone Season NOx Emissions Have Declined across the Region

Sources Achieved a High Level of Compliance

Decreases in Ozone Have Occurred since Implementation of the NBP

Changes in 8-Hour Ozone Nonattainment Areas in the east, 2001-2003 (Original Designations Versus 2004-2006)   Ozone Season NOx Emissions from All NBP Sources
This picture of the Eastern United States shows the changes in the 8 hour ozone nonattainment areas from 2001-2003.  The map shows small regions of air quality above the NAAQS standards around eastern US cities.   This bar chart shows the ozone season NOx emissions from all NBP sources.  Emissions in 1990 were 1,860,000 tons and in 2006 were 491,000 tons.
