Pratt & Whitney Canada Nova Scotia facility recognized for environmental excellence

June 4, 2008, Halifax – Pratt & Whitney Canada (P&WC) has received an Environmental
Excellence in Business award from Dalhousie University’s Eco-Efficiency
Centre for championing green practices at its Halifax, Nova Scotia
manufacturing facility. Pratt & Whitney Canada is a United
Technologies company.

The award was presented during the Centre’s 9^th
Annual Environmental Excellence in Business Breakfast this wee, coinciding with Canadian Environment Week. The event recognizes Nova
Scotia companies working on economic and environmental improvements
through innovative thinking and proactive strategies to reduce their
ecological footprint.

"We are honoured to be recognized for our
ongoing commitment to protect the environment," said Marc Paquet,
Halifax Plant Manager, P&WC. "This award is a tribute to all our
employees in Halifax, who are dedicated to conserving water, reducing
energy use and preserving our natural resources in our day-to-day
operations."

P&WC’s Halifax plant, which specializes in the
sub-assembly of engine components, precision machining of turbine
blades, and complex engine castings, was recognized for a number of
green initiatives.

• The plant has reduced its
  consumption of potable water by the equivalent of 168,000 gallons per
  year by removing silicates from water used in a chemical process tank,
  extending its life expectancy.
• Several large air
  conditioning units have been converted to a non-ozone depleting
  product, reducing carbon dioxide (CO2) emissions by 30 metric tons a
  year and energy usage by 15%.
• The replacement of solvent-based
  cleaning processes with an innovative water-based cleaner developed by
  P&WC has reduced overall process air emissions by over 70% in one
  year.

Dalhousie University’s Eco-Efficiency Centre, which is
celebrating its 10th anniversary this year, works with partners to
build a competitive economy that is sustainable for future generations.
It promotes responsible stewardship of resources, ecologically inspired
design of products and processes, technologies that are ecologically
and economically efficient and solutions that are innovative and
environmentally adaptable.
