The most important greenhouse gas is carbon dioxide (CO
2
). As part of Greenpeaces
campaign to protect the ozone layer, Greenpeace developed Greenfreeze technology,
which is a cooling system that is safre for the ozone layer and climate. Greenpeace
wants this solution to be applied throughout the world to replace [current]
refrigeration [technology].
In 1992, Greenpeace initiated the development of Greenfreeze, an ozone- and climate-
safe refrigeration technology. Greenfreeze uses a mixture of propane and isobutene
for this refrigerant. The technology has spread to other parts of the world. Cu
ba
decided in 1997 to convert its existing refrigerator factory to Greenfreeze technology.
Companies in Argentina, Turkey, and Russia are also set to produce Greenfreeze.
Strong interest
in the technology has also been expressed by companies in Tunisia,
India, Bangladesh, Ukraine, and Belarus.
Aerosols
Alternative application methods, such as stick and roll-on dispensers, mechanical
pump sprays, brushes and pads are among the wide variety of alternatives in
commercial use.
Alternative spray propellants include hydrocarbons,
and other compressed gases
such as air and CO2. Many developing countries have switched to, or have always
employed, propellants such as pentane and butane in industrial uses.
Even in medical applications, progress has been made. In Sweden and the Netherlands
over 60% of [people who suffer from asthma] are using dry-powder inhalers.
