National Multipollutant Emissions Comparison
Sometimes it is important to examine multiple pollutants together. The chart below compares the percent contribution from source sectors across the common pollutants. Ammonia is also shown because it contributes to particle pollution. This helps discern which sectors contribute to emissions of multiple pollutants. This comparison is based on the most recent emissions inventory.
