‘We essentially cook ourselves’ if we don’t fix air conditioning, major UN report warns

by Dharna Noor, Gizmodo


  • A new report from the United Nations shows that 460 billion tons of greenhouse gas emissions could be avoided worldwide by switching to energy-efficient, climate-safe air conditioning
  • There are 3.6 billion cooling appliances, including refrigerators, freezers, and air conditioning units in use around the globe
  • Chlorofluorocarbons (CFCs), chemicals that were once used in air conditioning units, among other products, were banned after the Montreal Protocol. However, their replacement, hydrofluorocarbons (HFCs) are also negatively impacting the climate as they are 11,700 times more warming than carbon dioxide
    • In 2019 governments adopted the Kigali Amendment to the Montreal Protocol in order to phase out HFCs
    • Doing so could avoid as much as 0.7 degrees Fahrenheit of warming if adopted globally
    • However, major emitters such as the US and India are two of the 90 countries that have not signed on
  • Doubling the energy efficiency of air conditioners could save up to $2.9 trillion by 2050
  • Promoting the construction of energy-efficient housing with alternative cooling options like green roofs will reduce the world’s need for air conditioning

Fossil fuel divestment and the transition to 100% clean energy is critical to achieving The Climate Center’s goals under the Climate-Safe California Platform.

Air conditioning is making the world a hotter place

by Justin Fox, Bloomberg

With two-thirds of the U.S. experiencing a heat wave, it seems like a good time to talk about air conditioning. According to the annual Characteristics of New Housingdata released by the Census Bureau early this month, 94% of the new housing units completed in the U.S. in 2018 came with it built in, up from 65% in 1974.

My first thought was that this might be a result of the southward shift of the U.S. population, and that is part of it. But air conditioning has made its biggest market-share gains outside the South.
