Celanese holds itself to high air emissions standards. We comply with local and national air standards, plus our own internal policies which in some cases are more stringent than applicable regulations. In every community where we do business, our facilities meet or exceed local, regional and national environmental air standards.

Air emissions discussed in this report focus on greenhouse gas (GHG) and volatile organic compounds (VOC). To reduce GHG climate-changing emissions -- primarily methane and carbon dioxide -- we recover heat from waste, use process-to-process heat exchangers, optimize process controls and modify reactor systems. Our staff continually reviews hazardous and non-hazardous waste products with the goal of finding beneficial uses for products of our operations.

Celanese operations worldwide have decreased GHG emissions through reduced energy consumption and improved efficiencies in our waste management processes. From 2006 to 2007, we reduced our total GHG footprint from 6.7 million metric tons to 5.5 million metric tons and our GHG index from 0.68 to 0.65 ton/ton.

Tools such as Six Sigma, digitization and advanced process engineering help us define and implement new solutions. From 2006 to 2007, we reduced our global VOC footprint from 5,706 metric tons to 4,876 metric tons. Our VOC index was largely unchanged primarily due to a production decrease.

Looking toward 2008 and beyond, we are on-track to meet or exceed our 2010 goal of a 30 percent reduction in our VOC index. We will achieve this primarily through a combination of control technologies and implementation of global best practices worldwide. Additionally, in place site-based initiatives will reduce emissions from nontraditional sources such as wastewater and fugitives, reportable in 2008 and beyond.
