Nairobi, 21 nov (EFE).-controlling the rise of global temperatures requires urgent action against a group of chemicals increasingly used, as the industrial gases known as HFCs (hydrofluorocarbons), warned today the United Nations programme for the environment (UNEP).
Los HFCs, which could make the temperature to rise by more than two degrees in the 21st century, used “air conditioning, refrigerators, material against fire and insulating foams machines”, and replaced more and more often to those who have been banned to protect the ozone layer, UNEP said in a statement issued from its headquarters in Nairobi.
UNEP today presented a report according to which by the year 2050 HFCs could cause the emission of 3.5 billion tons and 8,500 million tons of carbon dioxide, comparable to the current annual issue of the means of transport (about 6,000 or 7,000 million tonnes).
This report, entitled “HFC: link key in la protection of the climate and the layer of ozone”, is the first of the three that it intends to present UNEP this week, on the occasion of the Summit of climate change (COP 17) UN to be held in Durban (South Africa) from November 28 to December 9.
“More than 20 years of international effort to save the ozone layer is one of the best examples of cooperation between Nations,” which meant the removal of chlorofluorocarbon (CFC) in 2010, said today the executive director of UNEP, Achim Steiner.
However, said Steiner, Nations now have come to use HFCs, “Although not damaged and practically the ozone layer, yes causing a greenhouse effect”.
According to the head of UNEP, “the good news is that today there are alternatives,” do not use HFCs, as designing homes for the air conditioning is not necessary to use fiber instead of foam to insulate buildings. EFE
