Switching topics from reading test scores, here’s a downward trend Virginians can appreciate. Air pollution emissions in the Old Dominion continued their long-term downward trend in 2017 for most categories of emissions, according to an analysis of federal data by the Consumer Energy Alliance, an organization of major energy consumers.
Between 1990 and 2017 Virginia has seen the following:
• 68 percent reduction in carbon monoxide (CO)
• 51 percent reduction in ammonia (NH3)
• 61 percent reduction in nitrogen oxides (NOx)
• 30 percent reduction in coarse particulate matter (PM10)
• 35 percent reduction in fine particulate matter (PM2.5)
• 89 percent reduction in sulfur dioxide (SO2)
• 60 percent reduction in volatile organic compounds (VOCs
The state has achieved these gains despite a 35% increase in population, a 252% increase in GDP, and a 4% increase in vehicle miles driven per capita, says the report.
