The US Energy Department has announced its latest climate change goals to incorporate two new rules.
These proposed rules centre around commercial refrigeration equipment, walk-in coolers, fridges and supermarket displays and aim to cut energy bills by up to US$28bn and cut CO2 emissions by more than 350m metric tonnes over 30 years.

The first proposed rule is to improve energy-efficiency standards for commercial refrigeration equipment, which is estimated to save on energy bills by up to US$4bn in the US and result in CO2 emissions reductions of 55m metric tonnes.

The second rule is to improve energy efficiency standards for walk-in coolers and freezers.

Writing on the White House Blog last Thursday, deputy assistant to the President for energy and climate change Heather Zichal said that these 'critical steps' would 'bolster' the energy productivity of the US economy, shave energy costs for American families and businesses, and 'leave a healthier planet for future generations'.
