"As a worldwide leader, Otis has been working hard to establish a
direction for our industry that preserves the planet for future generations,"
said Didier Michaud-Daniel, president of Otis Elevator Company. "We have
introduced energy-efficient products and established two sustainable
manufacturing sites, while reducing our greenhouse gas emissions. Today, we
underscore Otis' steadfast commitment to show customers and suppliers The Way
To Green by continuing to set aggressive goals, maintain our innovative edge
and foster a strong culture of continuous improvement and efficiency."

As a multi-faceted, 'end-to-end' initiative, The Way to Green integrates
and builds upon the company's significant accomplishments to date, which
include:

    Products and services
    -- The award-winning line of Gen2(R) elevator systems featuring ReGen(TM)
       drives reduce energy consumption by up to 75 percent compared to
       conventional systems with non-regenerative drives. Under the
       prestigious European VDI 4707 standards, which assess elevator energy
       performance, the combined energy efficiency rating across the full
       range of Gen2 systems with standard configurations is class A, the
       highest rating possible. Verein Deutscher Ingenieure VDI (The
       Association of German Engineers) established its 4707 standards to
       assess elevator energy performance.
    -- The Gen2 system's coated steel belts and machine require no additional
       lubrication, eliminating the need for storage, cleanup and disposal of
       hazardous waste.
    -- LED illumination is now standard on Gen2 systems and lasts up to 10
       times longer than conventional fluorescent lamps. In addition, the
       advanced, automatic switch-off mode makes the lighting up to 80
       percent more efficient than conventional options.
    -- On Otis escalators and moving walkways, optional ReGen drives reduce
       energy consumption by up to 60 percent, an efficient automatic
       lubrication system reduces annual oil usage by up to 98 percent versus
       conventional systems, and LED lighting options are up to 30 percent
       more energy efficient.
    -- In maintaining its service portfolio of 1.7 million units worldwide,
       Otis proactively audits all operations, monitoring vehicle fleets, and
       optimizing service routes. This has enabled Otis to reduce worldwide
       greenhouse gas emissions by 12 percent from 2006 to 2010. Recycling,
       safe waste removal and environmentally friendly cleaners are also
       incorporated in all Otis' operations worldwide.

    Operations and manufacturing
    -- Otis implements processes that recycle 97 percent of industrial waste
       produced by Otis facilities.
    -- The Otis manufacturing facility in Madrid uses solar panels to
       generate about 60 percent of the site's energy needs.
    -- The Otis TEDA Manufacturing Center in China has achieved Gold-level
       Leadership in Energy and Environmental Design (LEED) certification.
       Advanced technologies in use at this location reduce energy usage by
       at least 25 percent compared to conventional design and manufacturing
       methods.
    -- By incorporating more efficient vehicles, by "right-sizing" vehicles
       to the job being performed and by launching innovative training
       programs focused on reducing fuel consumption, Otis has reduced
       greenhouse gas emissions from the company's transportation fleets by
       11 percent.
    -- Otis facilities have reduced water consumption by 12 percent by
       optimizing conservations through rainfall collection, recycling and
       the use of water-efficient fixtures.
    -- As a unit of United Technologies, Otis will take part in the
       corporation's voluntary pledge to reduce energy intensity by 25
       percent over the next decade. This commitment was made through the
       U.S. Department of Energy's Save Energy Now LEADER program.

More than 200,000 Gen2 elevator systems, covering a wide range of
applications, have been sold to date, making it the fastest selling product
in Otis company history. Notable installments of the system include Los
Angeles International Airport (LAX), Burj Khalifa (world's tallest building)
and Shanghai World Financial Center.

"Otis' global presence and growth will enable The Way to Green to
generate immediate and continuing environmental benefits for the thousands of
markets we serve," explained Michaud-Daniel. "Working with our employees,
suppliers and customers, we look forward to continuously improving our
environmental technologies and practices in the years to come."
