There are approximately 64 million domestic refrigerator-freezers
manufactured worldwide each year. The annual
growth rate in the refrigerator sector, especially in rapidly
developing countries like China, India and Indonesia is 15%, while
the growth rate in industrialized countries is 7%. In addition,
there are hundreds of millions of domestic refrigerator units
in use worldwide.
Until recently, most domestic refrigerators were
manufactured with the use of ozone depleting CFC-11 in the insulation,
and CFC-12 as the refrigerant. In 1990, the combined total of
CFC-11 and CFC-12 used in domestic refrigerators was approximately
40,000 metric tonnes.
In 1992, Greenpeace initiated the development of
the world's first ozone safe refrigerator technology - Greenfreeze.
Greenfreeze uses hydrocarbons as the blowing agent for the insulation
foam, and for the refrigerant. Hydrocarbons are completely ozone
friendly, and have minimal global warming potential.
Greenfreeze technology has revolutionized the domestic
refrigeration industry. It has spread like prairie wild-fire throughout
Western Europe and to other parts of the world, such as China
and Latin America, with extensive interest from countries such
as India, Cuba, Taiwan.
Greenfreeze technology is in direct competition for
market share with HCFC-141b and HFC-134a technologies, which are
environmentally unsustainable and technologically inferior.
Without the action of Greenpeace, the world would
now be on a different course, heading for a future in which millions
of consumers and businesses would be using chemicals which destroy
the ozone layer and which cause global warming.
