The 9% figure from the EPA report shook me last night
I was reading the new EPA emissions breakdown and found out commercial refrigeration accounts for 9% of US greenhouse gases. That's more than all passenger cars combined in some studies I saw. Has anyone looked into whether switching to natural refrigerants at local grocery stores is actually catching on?

Walmart and Target both made pledges to start phasing out HFCs in their coolers a few years back. But walk into any mid-size chain like Kroger or Safeway and half the cases are still running old refrigerant. The catch is the retrofit cost. Swapping a whole store's system runs into the six figures easy. Some places are testing CO2 transcritical systems now, mostly in new builds. Those work great in colder climates but lose efficiency when it's hot out. Until the EPA actually bans the old stuff instead of just reporting on it, most stores will keep kicking the can down the road.
