It turns out that the single most significant way to reduce CO2 emissions is to change the way we keep ourselves, and our food, cool. That's according to Project Drawdown, an organization working to identify, research and model the top solutions to climate change. But what makes cooling such a significant contributor to a warming planet? Refrigerators and air conditioners work by using chemicals to absorb and release heat, and while ozone-damaging CFCs and HCFCs have been largely phased out, their replacement -- HFCs -- are a climate change disaster, with a "1,000 to 9,000 times greater capacity to warm the atmosphere than carbon dioxide."
But as the stories in this collection (see below) demonstrate, people around the world are coming up with diverse and innovative solutions for keeping things cool. From district energy systems in Malaysia and storing snow in Japan and Sweden, to a zero-energy brick and charcoal fruit cooler in Kenya, technologies exist around the world for sustainably maintaining cold.
