Air emissions reductions

We continue to seek opportunities to reduce environmental impacts from our operations by reducing air emissions.

In 2012, our combined emissions of volatile organic compounds (VOCs), sulfur dioxide (SO2) and nitrogen oxides (NOx) decreased by nearly 8 percent from 2011, and has decreased 42 percent from 2002 levels.

For new projects, we evaluate the purchase of equipment like gas turbines that can reduce NOx emission levels. At our Baytown Olefins Plant, we deployed enhanced programs using a “SMART LDAR” camera that detects leaks and other fugitive emissions sources. In its first full year, the site estimates a 10 percent reduction in VOC emissions. We have purchased additional cameras and are increasing use of them globally.
