Membership in the World Index ranks Praxair among the top ten chemical companies worldwide in terms of sustainability leadership.

A significant portion of Praxair's annual revenues are derived from applications technologies which help our customers reduce their environmental footprint, improve their energy efficiency and/or increase the throughput, or yield of their production process, thereby decreasing their use of raw materials.
