Ranking and results by 2050
- 89.74 gigatons reduced CO2
- Cost? Too variable to be determined
- – $902.8 billion net savings
Located under the “Materials ” section in the book ” Drawdown” by Paul Hawken, is the number one issue and most important or effective for drawing CO2 levels down , REFRGERATION. All air conditioners, supermarket cases, and refrigerators contain chemical refrigerants that absorb and release heat, giving us the ability to keep ourselves and our food cool. Refrigerants were composed of CFC’s (chloroflourocarbons) and HFC’s (hydfrflorochlourocarbons), which have been phased out but are still in high circulation. These chemicals cause alot of the depletion of our stratospheric ozone layer. Even their replacement, HFC (hyfrofluorocarbons) , while not affecting the ozone layer, still warm the earth’s atmosphere 1 to 9 thousand times greater than carbon dioxide.
In 2016, officials made an amendment called the Kigali Deal to the Montreal Protocol to phase out HFC’s. Natural refrigerants, propane and ammonium, are now phasing in to our use. This Kagali deal, unlike the Paris climate agreement, is mandatory. It has set in place specific time tables and targets of action. Scientists estimate this action will reduce global warming by close to 1 degree Fahrenheit!
Refrigerant recovery , removal, and transformation and purification to other chemicals that do not cause global warming is becoming standard practice.
