For all their differences, Texas and California have a few big environmental challenges in common: large populations that drive significant miles on roadways, major industry that drives economic sustainability, and the resulting air pollution. Specifically, high levels of air toxics are linked to ozone pollution, and thus associated with higher risks of cancer and respiratory problems.
Fortunately, California has a new study detailing successes the state has had in addressing these issues – and it contains valuable lessons for Texas. The “Ambient and Emission Trends of Toxic Air Contaminants in California” study, authored by the California Air Resources Board (CARB) and published last month in Environmental Science and Technology, demonstrates how emissions and health risk have decreased due to landmark clean air standards on air toxics. Between 1990 and 2012, CARB monitored the seven most significant air toxics that are responsible for cancer risk in California and found that the state’s efforts resulted in a staggering 76 percent decline in the risk of cancer from exposure to air toxics.
