Significant air emissions are calculated based on site-specific data and published emission factors. We use the same boundary in calculating these air emissions as in our greenhouse gas emissions calculations. R-22 is an ozone depleting substance with a high global warming potential. BAC destroys R-22 from our operations when we decommission equipment instead of re-selling to encourage the complete phase out of R-22 from the market. The impact of air pollution (SOx, NOx, CO, VOCs, and PM) is calculated using social cost factors of each pollutant as reported in the World Resources Institute ’s Transport Emissions & Social Cost Assessment Tool v 1.0.
