Texas lays claim to the most extensive, aggressive air monitoring program in the nation. Despite its fast-growing population, Texas has seen significant air quality improvement over the last ten years. Successes include:
From 2000 to 2011, ozone levels in Texas decreased by 23 percent.
To date, there are 74 stationary air monitors that measure volatile organic compounds (VOCs), like benzene, in the state of Texas, more than in any other state.
Between 2000 and 2011, point-source nitrogen oxide (NOx) emissions decreased 60 percent, and measured ground-level ozone concentrations decreased 23 percent.
Of the 20 states with the highest power-plant NOx emissions, Texas ranks third in lowest emissions per capita.
