DENR Policy on Car Aircon

DENR-6 advises motorists of new policies on car aircon
Iloilo City (22 November 2005) -- The Department of Environment and Natural Resources advises all car owners that effective January 1, 2006, registration of vehicles will be regulated in accordance with the National Chlorofluorocarbons (CFC) Phase-out Plan.

RED Celso V. Loriega, Jr. said that car owners should check the models of their vehicles. All vehicles of 1999 models and up that still use CFC 12 or Freon in their airconditioners shall not be allowed to register or renew their registration with the LTO. All old model vehicles with CFC-using airconditioning system will only be allowed to ply the road until 2012. This restriction is to encourage vehicle owners to use cooling agents in their vehicles such as hydroflourocarbons (HFC-134A) and other blends, which are more ozone-friendly alternatives.

RD Bienvenido Lipayon of the DENR Environmental Management Bureau said that he had already coordinated with the regional LTO office to explain to the various transport groups and motorists regarding the need to phase-out CFC- 12 or Freon in mobile air-conditioning units.

The phase-out of ozone depleting substances is a commitment of the Philippine government as one of the 188 country-signatories to the Montreal Protocol on Substances that Deplete the Ozone Layer. We are committed to reduce and eventually phase-out the production and consumption of ozone depleting substances. Among these are the CFC used as cooling agent for refrigerators and air conditioners, blowing agent for foams, propellant for aerosol and metered-dose inhaler, and cleaning agent for computer circuit boards. Under the Montreal Protocol schedules, CFCs are set for total phase out by 2010 in the Philippines.

Engr. Virgilio Fabronero of EMB explained that chlorofluorocarbons or CFC is a chemical which consists of carbon, chlorine and fluorine atoms. It was discovered in 1928 and was considered a miracle compound in 1930 having the quality of an ideal chemical-seemingly harmless to humans and the environment, inert and immensely stable, odorless, non-flammable, non corrosive and non toxic, inexpensive to produce and easy to store.

The most ozone-depleting CFCs having a potential of 1.0 are CFC 11 (Trichoroflouromethane) CFC 12 (Dichlorodiflouromethane), CFC 13 (Chlorotriflouromethane), and CFC 114 (Dichlorotetraflouroethane). Others ranges from.8 to .33. CFC known as Freon has a lifetime up to 100 years. Each chlorine atom that breaks away from the CFC compound can destroy up to 100,000 ozone molecules. The rapid destruction of the ozone layer can open a hole for the UV rays of the sun to penetrate to the earth surface thus creates harm to human beings and every living thing. The only way to prevent this is to stop using CFCs.

One of the strategies to stop the use of Freon is to ban its importation. It is also imperative that old models of vehicles should now gradually retrofit their air conditioning units so that they can already use the ozone-friendly chemicals and technologies.

John 3:16-18 ESV
For God so loved the world, that he gave his only Son (Jesus Christ), that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
