Indo-US task force to study HFC phase-down

India and the US have agreed to establish an Indo-US Technical Task Force on hydrofluorocarbons, or HFCs—super greenhouse gases. The global warming potentials (GWP) of HFCs range from 140 (HFC-152a) to 11,700 (HFC-23), according to the US EPA.

India’s Minister of Environment, Jairam Ramesh, hosted US Deputy Assistant Secretary of State for Environment, Daniel A. Reifsnyder, in New Delhi, along with members of industry and civil society groups to discuss the HFC issue. The Joint Task Force will submit its report by 1 August 2011.

HFCs are chemicals are potential substitutes for ozone-depleting and climate-warming CFCs and HCFCs currently being phased out under the Montreal Protocol treaty to protect the ozone layer. Although they don’t harm the ozone layer, HFCs are powerful climate warming gases and their emissions are expected to rise sharply over the next few decades without aggressive action, significantly contributing to climate change.

The task force will include industry representatives, scientists, and government officials from India and the US to evaluate a phase-down of the production and use of HFCs under the Montreal Protocol.

Reducing HFC emissions under the Montreal Protocol is the biggest, fastest piece of climate mitigation available to the world in the next few years and Minister Ramesh is one of the best-positioned people to lead the world on this important opportunity.

Minister Ramesh was a key climate leader in the Cancun talks last December, helping broker an outcome that moved the multilateral process forward to the next meeting of the UN climate talks in Durban, South Africa later this year.

Last year, the Federated States of Micronesia along with other vulnerable island countries proposed an amendment to the ozone treaty to phase down the production and use of HFCs. Once agreed, the amendment would ensure climate mitigation of up to 100 billion tonnes of CO2-equivalent by 2050, many times more than the Kyoto Protocol climate treaty. The United States, Mexico, and Canada also proposed a similar amendment.

Although India—with concerns about alternatives and available financing—did not voice support for the 2010 Micronesia or North American proposals, Minister Ramesh acknowledged on Friday that with international financing and technology support, there is no reason why India should not lead in the phase-down of HFCs.

Use isobutane and propane. Even with HFCs having a large greenhouse effect, they are produced in far too small a volume to even be noticed with all the methane and CO2 and H2O being released. The makers of HFCs are not to blame for their releases, but it is the people who do it, and if people are removed from the earth, then global warming is no longer a problem. Just because something causes heat retention is no reason to ban it. Water does it so ban water. People are the clear source of global warming so ban them. ..HG..
