› Introduction
In the United States, environmental and technological standards for the automotive sector are set at the Federal and State level. The main actor at the federal level is the Environmental Protection Agency (EPA), which enforces environmental laws enacted by the Congress, and develops research programmes.

|
In addition, each of the 50 U.S. States is allowed to implement additional rules, if they meet the minimum standards set at the Federal level.
As an independent global body, the Society of Automotive Engineers (SAE) provides certification and engineering standards for the automotive sector, including Mobile Air Conditioning systems (MAC). |
› Overview
There are four major sources with an impact on Mobile Air Conditioning systems (MAC):
- The Clean Air Act is the basic Federal law for emission from any stationary or mobile source. It rules the phase-out of ozone-depleting chemicals. Since 1990, it has regulated refrigerants in MAC systems and their recycling.
- The Significant New Alternative Policy (SNAP) reviews and regulates alternatives for refrigerants in MAC that will be phased out. SNAP recognizes R744 as an acceptable substitute.
- The Mobile Air Conditioning Climate Protection Partnership identifies alternatives for the refrigerant HFC-134a and supports innovative MAC technologies. Within the frame of the partnership, the SAE J-2727 standard rules testing procedures for MAC and certifies improved systems.
- The California Global Warming Solutions Act of 2006 (AB 32) is the nation’s first cap on global warming. The Act and a bill targeting passenger cars’ emissions in particular, regulate greenhouse gas emissions from automobiles.
