With the recent climate agreement in Paris, many countries are looking at improved energy efficiency as a way to reduce greenhouse gas (GHG) emissions to contribute to the agreed climate goal of keeping global warming below two degrees Celsius.
Innovative air-conditioning (A/C) technology, just launched by a Thai A/C manufacturer in cooperation with the Government of Thailand and the Federation of Thai Industries, will not only save consumers and the country energy, it will eliminate emissions of ozone depleting, high global warming refrigerants with little to no additional costs. At scale, this technology can play an important role in global climate mitigation efforts.

Last month, China was granted US$95 million to reduce its production of hydro-chlorofluorocarbons (HCFCs), substances that are used primarily for cooling, refrigeration, and the manufacture of foam products. The funding comes from the Multilateral Fund (MLF) of the Montreal Protocol, because HCFCs deplete the ozone layer and are controlled under the Protocol. With access to these funds, between now and 2015 China will reduce its production of HCFCs by 10%, or 47,000 metric tons from 2010 levels, allowing it to meet the first reduction targets set by the Protocol.
This alone is worth celebrating because China is the world's largest producer of HCFCs. Nearly 50% of its production is consumed by other developing countries, all of whom also face HCFC consumption reduction targets under the Protocol. Herein lies one secret to the Protocol’s success: its ability to regulate both production and consumption worldwide simultaneously, putting into practice an economist’s dream to tackle both supply and demand in tandem. By addressing the supply side of the problem through support to China’s production phase-out, the demand side - in China and in developing countries around the world - can build a sustainable HCFC consumption phase-out response. The ozone layer, and human and environmental health, will all be the better for it.
