“…A calculation model, called RIEP (Refrigerant Inventories and Emission Previsions), was developed based on a bottom-up approach as defined in IPCC 2000 [IPC00]. The work done by the CEP during the last eight years was taken into account for the update of the Tier 2 method as described in the IPCC 2006 guidelines [CLO05], [ASH04]. The covered sub-sectors are those listed previously, defined by the IPCC 2006 guidelines, and the disaggregation leads to the definition of 35 sub-sectors.…”

“…These emissions are usually higher for field-assembled and fieldcharged equipment than for the factory-produced ones. For example, these emissions include those taking place when hoses and valves are being connected or disconnected [CLO05].…”

“…These emissions are a function of ambient temperature conditions, with higher leaks occurring in warmer climates. We estimate regular leaks for each city by exponentially fitting the best available experimental regular emissions data reported by taken at three ambient temperatures (30 °C, 40 °C, and 50 °C), using eq . R i = 2.836796603 0.06393 T i = any city The latest version (3b) of the model allows for a leak rate correction using an average SAE J2727 value of 8.8 g yr −1 for each city in the model as provided in ref .…”

In 2008, 95% of the vehicle fleet in the developed countries and 80% of fleet in the developing countries were equipped with mobile air conditioning systems (MACs). Greenhouse gases (GHGs) are emitted due to refrigerant leakage (direct emissions) and due to the energy consumed by MACs operation (indirect emissions). In response to reducing the global warming impact of MACs, policy makers and the industry are investigating alternative refrigerant systems that use low global warming potential (GWP) refrigerants. The GREEN-MAC-LCCP model assesses the direct and indirect CO(2) equivalent emissions related to MACs usage, as well as those associated with the production, use and disposal of alternative refrigerants and MACs components. This model provides a platform for simple data input and provides an output summary as well as details that can be analyzed in a custom fashion by the user. It provides engineers and policy makers a state-of-the-art tool, based on sound engineering data and methods, in order to facilitate the process of evaluating alternate refrigerants with low lifecycle global warming impact as well as providing the total impact of any MACs on the environment. It has been recognized as the standard of the MACs industry.
