In Rwanda, Africa, almost 200 countries signed the agreement, which must reduce greenhouse gas emissions from air conditioning. We are talking about the HFCs – according to scientists, their negative impact on climate can be thousands of times worse than carbon dioxide, notes the BBC Russian service. In early October, was ratified by the Paris agreement on climate change, regulating greenhouse gas emissions in General.
As pointed out by Reuters, many wealthy countries have already started to reduce the use of hydrofluorocarbons in the production of air conditioners and refrigerators. The agreement should, in time, to extend this approach to a large part of the world.
The agreement to reduce the use of hydrofluorocarbons has been achieved in the capital of Rwanda – Kigali. According to the deal, all countries are divided into three groups.
The first group includes developed countries, including the US and most European countries. They should reduce the use of HFCs by 10% by 2019, and by 85% by 2036.
The second and third groups of developing countries will no longer increase the use of hydrofluorocarbons in 2024 and 2028 years respectively. After that they will begin reducing the use of these harmful substances.
Manufacturers of refrigerators and air conditioners have started to use HFCs after was banned chlorofluorocarbons. These substances destroy the ozone layer, and they decided to replace HFCs. The replacement worked, but it was later revealed that HFCs hold heat in the atmosphere several thousand times more effective than carbon dioxide. Emissions of hydrofluorocarbons are steadily growing at 10-15% per year, as the demand for air conditioners is increasing, especially in developing countries.
U.S. Secretary of state John Kerry called the agreement reached in Kigali, the agreement “a giant step forward.”
