Nitrogen fertilizer manufacturing is an energy-intensive process. That’s why we regularly invest in capital improvement projects that enable us to improve energy efficiency and reduce emissions. In 2014, these improvements included energy-reduction projects at our Verdigris, Oklahoma, complex that resulted in approximate savings of 476,000 MMBtus, the equivalent average energy consumption of about 13,000 U.S. homes annually. We also installed selective catalytic reduction systems at two plants in Port Neal, Iowa, to reduce nitrous oxide emissions. In addition, new plants at Port Neal, Iowa, and Donaldsonville, Louisiana, include energy-efficient, state-of-the-art technology.

We not only invest in our own plants to make them run more efficiently and cleaner, but we also manufacture products that help other industries realize their own environmental goals. We are, for example, one of the largest producers in North America of Diesel Exhaust Fluid (DEF), which helps reduce nitrous oxide emissions of heavy-duty trucks by up to 90 percent and improve fuel efficiency by up to five percent.
