Most importantly, we noted the fact that the industry is transitioning to low emissions technology because doing so will reduces HVACR energy consumption and GHG emissions. They are two sides to the same coin. Low emissions HVACR technology is energy efficient technology.

Since that newsletter came out, there has been considerable evidence of and impetus to change driven by international agreements. China and the US have agreed a broad agenda of emissions reduction including the commitment to phase down the use of HFC refrigerants. This agreement is similar to the initiative by the European Union to phase down HFC use by 79 per cent by 2030.

The Climate and Clean Air Coalition, comprised of 40 countries in association with UNEP, including Australia, has endorsed this policy and established an international working group specifically for the purpose. As a result, original equipment manufacturers worldwide are embracing the need to deliver refrigeration and air conditioning systems that are based on low-GWP refrigerants.
