                      Most of our air emissions come from burning fuel to produce energy. Many of our air quality improvements are the result of process modifications at our mills, the use of lower-emitting additives in our products, and pollution-control equipment that captures or destroys significant amounts of air emissions.  In the last two years, we made significant improvements including capital investments at several mills that included cleaner burning units, energy optimization and upgrades to emission control systems that helped reduce our carbon monoxide emissions by 24 percent from 2016 levels. These improvements also helped to lower our nitrogen oxides (NOx), sulfur oxides (SOx) and volatile organic compound emissions.

                      Another noteworthy event that occurred in 2018 was the opening of our new complex in Dierks, Arkansas with all modern equipment including four new continuous drying kilns, a planer and a facility for processing finished goods.

                      We continue to work on additional reductions, including significant upgrades to many of our facilities to comply with new regulations limiting hazardous air pollutant emissions from boilers and process heaters.

                      We share our company-wide air-quality data and invite you to look.

                      Our air emission accounting is most often based on emission factors and actual or estimated production levels at each site, making these numbers challenging to roll up and compare year-to-year. Over time, we noticed our emissions were changing more from accounting practices and revisions to emission factors rather than from actual process changes. Rather than set annual goals we are focused on facility-level improvements and meeting new, stricter air-quality regulations.
