Calculating carbon emissions is a complex process. The different types of emissions need to be identified and collected company wide. From this information, the amount of each type of gas released into the environment needs to be calculated. In addition, tracking methods need to show the daily use of refrigerant gas. The end result will show the global warming potential for each facility with a refrigeration and air-conditioning (RAC) system or heating, ventilation and air conditioning (HVAC) system. Refrigerant systems use high levels of greenhouse gases, so the EPA established the Climate Registry Protocol for calculating carbon emissions on a regular basis. The international equivalent of this requirement is outlined in the Montreal Protocol and Kyoto Protocol. The main purpose for calculating carbon emissions is to begin reducing the damaging effects that refrigerant gas has on the environment. Commercial refrigeration and air-conditioning (RAC) systems or heating, ventilation and air conditioning (HVAC) systems operate on refrigerant gas, which is made up of hydrochlorofluorocarbons (HCFCs), chlorofluorocarbons (CFCs) and perfluorocarbons (PFCs). When broken down, these substances contain carbon, chlorine, fluorine and hydrogen. These gases are major ozone depleting substances. By calculating carbon emissions, government environmental agencies will be able to better understand the situation. Companies who fail to report their carbon emissions will be issued a substantial fine. Various carbon emissions reporting protocols have emerged from the EPA, ISO, World Resource Institute, and Climate Registry protocols. All of these documents define in great detail how organizations must collect data, calculate carbon emissions, and report the results. In short, the monitoring, tracking, and reporting requirements mandate that all locations where refrigerants are being used or serviced must collect, organize, and calculate as part of an enterprise's carbon emissions. Some volume of carbon is released into the environment by any company with a refrigerant system. Trying to determine how much carbon is emitted is an intricate process. Calculating carbon emissions begins by collecting data across the entire company and all its locations and identifying the gases. From there, a determination on how much of each gas is released must be made. Then various reports that include tracking methods need to be completed and submitted. Refrigerant management programs can best handle the tedious process of calculating carbon emissions. With so many components involved, a computerized refrigerant management program is much more effective than manually handling and reviewing paper reports. A refrigerant management program that includes a solution for refrigerant gas tracking and an automated way to calculate carbon emissions is important. Solutions like this make is easier to handle calculating carbon emissions for all AC/HVAC systems operated by a company. There are several reasons that led to the EPA and international environmental agencies to require companies to include calculating carbon emissions in their reports. It is an important step to define your organizational boundaries, where you do business, and to identify the refrigerants you own or other sources of greenhouse gases (GHGs). Equally important is to establish a tracking mechanism for determining how much harmful gases are released at any given time. The information and data collected for the emerging refrigerant management programs will enhance and improve atmospheric conditions with specific requirements for reducing carbon (CO2) emissions. By calculating carbon emissions, companies will be able to recognize the extent of their carbon footprint. For companies with multiple locations using refrigeration and air-conditioning (RAC) systems or heating, ventilation and air conditioning (HVAC) systems, the task becomes even more critical. But there is help to address this challenging issue. Emerging software provided by clean-tech development firms track carbon dioxide gas emissions across all sites so companies can do their part to ensure a healthy environment for years to come.
