Earth from space
Greenpeace has always fought to defend the atmosphere from industrial pollution.
From the early 1980s, we confronted factories across Europe and North America who were causing acid rain and documented its effects: dead lakes and forests and acid-eroded historic buildings.
Greenpeace also launched an international campaign to halt the depletion of the ozone layer. In 1992 Greenpeace scientists developed Greenfreeze, a refrigeration technology that uses hydrocarbons in place of ozone-eating CFCs and climate-busting HCFCs and HFCs. Greenfreeze was the world's first refrigerator technology which is safe both for the ozone layer and the climate and it has spread like wildfire throughout Western Europe and to other parts of the world.
