In an August 29 blog post, Deputy Assistant to the President for Energy and Climate Change Heather Zichal commented that proposed energy efficiency rules for commercial refrigerators and walk-in coolers and freezers will result in significant energy and monetary savings. The refrigerators rule will save $4 billion and curb carbon dioxide emissions by 55 MMT over 30 years and the walk-in coolers and freezers rule will save $24 billion and cut 298 MMT of carbon dioxide emissions over the same time frame. The rules will be finalized next year.
