Can’t reduce refrigeration. That’s too important to the food supply.Ran some numbers based on greenhouse gas emission percentages (EPA) and the relative 100-year global warming potential of each greenhouse gas (National Oceanic and Atmospheric Administration).
Punch line is that the U.S. transportation sector (including commercial vehicles, airplanes, etc.) comprises only 0.5% of the country's hypothetical global warming impact. Passenger vehicles are responsible for about 40% of that amount.
According to government data, the main culprit of anthropogenic global warming is refrigeration and air conditioning, which is responsible for 82% of the U.S.'s hypothetical global warming impact.
What is my math missing? Why do we care about reducing automobile emissions when the benefit of cutting them to zero would be a rounding error?

AC on the other hand is a luxury that’s really hard to cut. I’ve been trying to lower my electric bill by reducing my AC usage in my house and not just sitting at home sucking up AC. It’s tough.
