Celanese Manufacturing Facilities Recognized for Achieving ENERGY STAR® Challenge for Industry

DALLAS & FRANKFURT, Germany–(BUSINESS WIRE)–$CE #Celanese–Celanese Corporation (NYSE: CE), a global technology and specialty
materials company, today announced that its Bay City, Texas vinyl
acetate monomer (VAM) and Frankfurt, Germany polyoxymethylene (POM)
manufacturing facilities have been recognized by the U.S. Environmental
Protection Agency (EPA) for achieving the ENERGY STAR® Challenge for
Industry (the Challenge) in 2017.

The Challenge is a national call-to-action by the EPA to improve the
energy efficiency of America’s manufacturers by 10 percent or more. By
taking the Challenge, manufacturing sites set a goal to reduce their
energy intensity by 10 percent within five years. Although the Challenge
is a U.S.-centric initiative, Celanese’s facilities outside the U.S.
participate in the Challenge as part of the company’s commitment to
global environmental stewardship.

“By achieving the ENERGY STAR® Challenge for Industry, the Bay City VAM
and Frankfurt POM facilities have reduced more than 150,000 tons of
greenhouse gas emissions caused by energy usage and have saved enough
energy to power 16,000 homes annually,” said Jon Mortimer, Vice
President of Global Manufacturing for Celanese. “Taking the Challenge
and achieving these significant energy reduction milestones demonstrates
Celanese’s commitment to strong energy management practices that produce
positive results for the environment, our customers and our communities.”

These facilities used a variety of creative approaches which yielded a
reduction of their energy intensity by 14.4 percent and 13.4 percent,
respectively, within two years.

Celanese, an ENERGY STAR® partner since 2014, has been recognized by the
U.S. EPA for its superior performance in energy management and for
outstanding contributions to protecting the environment through energy
efficiency. Celanese has been designated as an ENERGY STAR Partner of
the Year for 2016 and 2017.
