lights with light emitting diodes (LEDs) in many signs and
decorations including numerous holiday installations.
In 2006 Disneyland Resort invested in a Central Energy
Plant and permanently eliminated eight combustion sources,
all of which produced nitrogen oxide, a major contributor
to smog. The Hotel also replaced two old boilers with new
state-of-the-art, high efficiency water heaters that burn
natural gas. This renovation is projected to reduce annual
natural gas usage by as much as 200 million cubic feet,
equivalent to a full year’s usage of approximately 1,500
homes, and will reduce annual CO CO, NO emissions by
2 x
11,000, 240, and 30 tons respectively.
At Tokyo Disney Resort, a Central Energy Plant provides
energy to all facilities of Tokyo Disney Sea Park, and col-
lects and reuses waste heat to produce steam with help
from a boiler. Power is generated using a gas turbine sys-
tem fueled by municipal gas, providing approximately
16% of the power required. Likewise, the Tokyo Disney-
land Central Energy Plant was rebuilt to increase energy-
efficiency, eliminating the need for local air compressors
and leading to a 10% decrease in air-conditioning-related
energy consumption.

A more recent adopter is Hilton Hotels Corporation, which in
2008 announced short and long term goals for building sustainabil-
ity into the core fabric of its businesses. By 2014, the worldwide hotel
chain aims to reduce direct energy consumption, CO emissions, and
2
solid waste by 20%, and water consumption by 10%. In addition, the
company will focus on high-impact areas, such as sustainable build-
ing design, construction, and operations and renewable energy infra-
structure for hotels and corporate offices. Already, in the European
region, energy and water consumption were reduced by 10% from
2005 to 2007, and in the United Kingdom and Ireland, introduction
of carbon-free electricity has reduced CO emissions in participating
2
Hilton hotels by more than 56%. In the United States, Hilton was the
first in the hotel industry to install a commercial fuel cell system
atop the Hilton New York.
