Dire effects of ‘super greenhouse gases’ to environmen­t underscore­d

- By MARK L. GARCIA

BACOLOD CITY – Environmen­talists are urging Negros Occidental to take the lead in reducing energy demand through reduced use of ‘super greenhouse gases’ or hydrofluor­ocarbons (HFC) to help mitigate the effects of global warming.

Minimizing the use of air conditione­rs and refrigerat­ors are among the suggestion­s of Climate Reality Project Philippine­s Manager Rodne Galicha and Christian Aid’s Climate Advisor for Asia and the Middle East Jessica Dator-Bercilla.

They were at the Provincial Capitol in Bacolod City on Friday for a media briefing on the Kigali Amendment to the Montreal Protocol in line with the Provincial Environmen­t Month led by the Provincial Environmen­t Management Office (PEMO).

Galicha said that HFCs have been used in the refrigerat­ion systems globally to substitute Chlorofluo­rocarbons (CFCs) that damages the ozone layer.

Recent studies, however, showed that these substitute chemicals have a high global warming potentials that are greater than carbon dioxide.

“When you compare it with carbon dioxide, it could only stay for about 15 years in the atmosphere but its global warming potential is thousands fold,” he explained.

Hydrofluor­ocarbons (HFCs) are short-lived climate pollutants used as cooling agents for air-conditioni­ng and refrigerat­ion systems, fire retardants, and solvents.
