Reducing Greenhouse Gases

Synthetic refrigerants such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) have a negative impact on the earth’s atmosphere. The CFCs and HCFCs destroy the protective ozone layer so that the sun’s aggressive ultraviolet rays can reach the surface. The radiation causes genetic damage in the cells of people, plants and animals. Therefore, the international Montreal Protocol started the phase-out of ozone depleting substances in 1987. With success: According to the latest  scientific assessment by the World Meteorology Organization and UNEP the ozone layer could recover to a large extent by 2050.

The ozone-friendly successors however, the also synthetic hydrofluorocarbons (HFCs), contribute to global warming up to 4,000 times more than CO2. Even though they are specified as greenhouse gases under the Kyoto Protocol, they are still widely used in refrigeration appliances. The concentration of greenhouse gases in the atmosphere is at an all-time high and the contribution of HFCs is growing.

Therefore, Refrigerants, Naturally! looked for alternatives. Our member companies support climate-friendly technologies.

 

A sustainable alternative for HFCs is already on the market - natural refrigerants: Hydrocarbons such as propane and iso-butane, carbon dioxide, ammonia, water or air. They can all be found in nature. In the amounts used in refrigeration their greenhouse gas emissions have no or negligible impact on the climate.

Therefore we, the members of Refrigerants, Naturally!, replace harmful fluorinated gases –CFCs, HCFCs and HFCs – in our point-of-sales cooling and freezing units. We are especially concerned with improving or at least maintaining energy efficiency in our new technologies.
