Hydrofluorocarbons (HFCs) are commonly used as refrigerants in Refrigeration and Air-Conditioning (RAC)equipment and have high Global Warming Potential (GWP [1]).In the atmosphere, HFCs are much more potent greenhouse gases than carbon dioxide and contribute significantly to global warming. On one calculation, replacing refrigerants that damage the atmosphere would reduce total greenhouse gases by the equivalent of 90bn tonnes of . How air conditioning could keep everyone cool without cooking the planet In a hotter world, people will need more cooling. Of that figure,. The result is an accumulation of substances in these applications which forms a previously unrecognized additional risk for climate change. With the world going green, air conditioning is becoming frowned at even though . And according to a Natural Resources Defense Council (NRDC) study, over its lifetime, a new air-source heat pump can reduce greenhouse gas emissions by 46 to 54 percent compared to natural gas alternatives. The researchers found that air conditioning is responsible for the equivalent of 1,950 million tons of carbon dioxide released annually — or 3.94 percent of global greenhouse gas emissions. Painted rooftops reflect the heat instead of absorbing it, reducing the need for air-conditioning and cutting greenhouse gases. The new research shows global emissions of HFCs have risen by more than half between 2007 and 2012. The proliferation of suburban development around city centers creates urban sprawl. HFCs are potent greenhouse gases commonly used in refrigeration and air conditioning equipment, as well as foams and many other applications. How to transition to heat pumps Air conditioners and fridges contain potent greenhouse gases known as hydrofluorocarbons (HFCs). The researchers calculated air conditioning is responsible for the equivalent of 1,950 million tons of carbon dioxide released annually, or 3.94% of global greenhouse gas emissions. World's Air Conditioning Boom Would Worsen Greenhouse Gas Emissions: Study Nations with emerging economies and spiking populations, including India and Brazil, are seeing air conditioner sales grow. Though these do not deplete Earth's ozone layer in the way the chlorofluorocarbons they replaced back in the mid . Keywords: GHG emissions, motor air conditioning, refrigerants Hydrofluorocarbons (HFCs) used in mobile air conditioning (MAC) and refrigeration equipment are an important contributor to greenhouse gas (GHG) emissions from motor vehicles. Most air conditioners use refrigerant gases called hydrofluorocarbons ( HFC s). In California, HFCs account for 4% to 5 % of greenhouse gas emissions today, said Pamela Gupta, a manager overseeing HFC regulations at the California Air Resources Board. • Direct emissions from purchased industrial gases. But the demand for refrigeration and cooling is growing as Earth warms, Gupta says: "They are the fastest growing source of greenhouse gas emissions in California . Yet outdoor air conditioning is part of a vicious cycle. As a greenhouse gas, HFCs are up to 12,000 times more potent as carbon dioxide as an agent causing climate change.
