New Delhi, (Agencies): India and the US on Friday set up a task force with the aim of reducing gases which cause global warming amid New Delhi's emphasis on a four-layered approach including international treaties and national level regulations and incentives to deal with the issue.

The decision to set up the task force was taken at a Joint Indo-US workshop on HydroFluoroCarbons (HFCs) attended by Environment Minister Jairam Ramesh and US Deputy Assistant Secretary of State for Environment Daniel A Reifsnyder.

"At the conclusion of the meeting it was decided to establish a Joint Indo-US Technical Task Force comprising industry representatives, scientists, and government officials to suggest options for HFC phase-down," the Environment Ministry said in a statement.

"The Joint Task Force will submit its report latest by August 1, 2011," it said.

Speaking at the workshop, Ramesh said, "India recognizes that while HFCs, a substitute for CFCs and HCFCs, are a 'solution' from an ozone depletion perspective, they are a 'problem' from climate change perspective, since they have high global warming potential."

HFCs are a substitute for ozone depleting gases chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).

Speaking on the occasion, Reifsnyder noted the need for the transition out of HFCs, and emphasised that an early transition would help avoid high costs.

He said that the US was advocating a "phase-down", and not a "phase-out" of HFCs.
