HCFCs destroy part of the atmosphere that protects against ultraviolet rays.
Substance used in refrigeration and sprays should be abolished by 2040.
It was introduced on Wednesday (27) Brazilian Program for the Elimination Hidroclofluorcarbonos (PBH), which aims to organize the replacement of these substances by others that are less harmful to the environment. The measure was published by Official Gazette
The hidroclofluorcarbonos (HCFCs) are now used widely in the 1980s and 1990s, to replace chlorofluorocarbons (CFCs). These gases are used in cooling - from refrigerators to air conditioners - and foams and sprays.
CFCs have been eliminated from an international agreement called the Montreal Protocol, signed in 1987 because it was proved that they were causing the increase of the hole in the ozone layer.
At the time, HCFCs emerged as an alternative, since they had the same destructive effect. However, they are still harmful to the ozone layer, and today there are other products used for the same purpose. Therefore, a recent review of the Montreal Protocol has proposed a gradual reduction in the use of HCFCs until their complete elimination in 2040.
The ozone layer shields the earth from the sun's ultraviolet rays that can cause skin cancer. By eliminating the use of CFCs, the hole located mainly over Antarctica is stable, and experts believe that the ozone layer will return to levels it had in 1980 until mid-century.
According to Magna Luduvice, coordinator of protection of the ozone layer of the Ministry of Environment, the institution of PBH is a milestone, but does not represent a change in the direction of environmental protection measures.
"We are preparing this program for years," said Luduvice. "The decree officially instituted only."
The representative of the Ministry explained that the initiative is a partnership between the government and the private sector. On the one hand, the Brazilian Institute of Environment and Natural Resources (IBAMA) controls the import of HCFCs - these products are not made in Brazil. On the other hand, companies that need to receive the substance tech support and commit to reduce their use.
Last week, the Brazilian Institute of Geography and Statistics (IBGE) showed that the emission of HCFCs increased between 2000 and 2010. According Luduvice, this increase was expected, as it represented an "intermediate step" to eliminate CFCs and thus served to protect the ozone layer.
In 2013, Brazil can not exceed the average level of emissions for the years 2009 and 2010. In 2015, the reduction shall be 10%. In 2020, 35%. In 2025, 67.5%. In 2030, 97.5%. In 2040, the elimination of HCFCs must be total.
