Fugitive Emission 1.2. Fugitive Emissions Calculation Engine - Help Page Fugitive emissions refer to leaks or uncontrolled releases of gases, primarily from HVAC systems (heating, ventilation, and air conditioning), refrigeration equipment, fire suppression systems, and other gas-based systems. These emissions typically result from the escape of refrigerants, which contain greenhouse gases (GHGs) that contribute significantly to global warming. The Fugitive Emissions Calculation Engine is designed to accurately calculate and report these types of emissions, which are generally classified under Scope 1 as direct GHG emissions. ### How to Use the Calculation Engine **Identify Equipment Types and Refrigerants:** * Begin by identifying which equipment (e.g., air conditioners, refrigerators, fire suppression systems) has the potential for fugitive emissions. * Select the types of refrigerants used in these systems (e.g., R-22, R-134a, R-410A). ### **Determine Annual Leakage Rate:** * For each type of equipment, determine the annual leakage rate, usually expressed as a percentage of the total refrigerant capacity of the equipment. * Use direct measurement data if available. If not, standard leakage rates recommended by authorities like the IPCC or EPA can be used. ### **Review Purchase Records:** * When determining the annual leakage rate, you can also review the equipment’s refrigerant purchase and refill records. This approach helps track annual refrigerant consumption and aids in calculating a more accurate leakage rate. ### **Input Leakage Data:** * Enter the equipment capacity (e.g., the amount of refrigerant in kilograms) and the determined annual leakage rate. * The calculation engine will use these inputs to estimate the amount of refrigerant that leaks into the atmosphere annually. ### **Apply Emission Factors:** * The calculation engine automatically applies a specific emission factor (Global Warming Potential - GWP) for each type of refrigerant. * The GWP factor indicates the CO₂ equivalent emission potential of the refrigerant. For example, R-410A has a GWP of 2088, meaning its impact on global warming is 2088 times that of CO₂. ### **Calculate Total Emissions:** * Based on the input data and applied GWP values, the calculation engine computes the total amount of fugitive emissions and expresses it as CO₂ equivalent (CO₂e). * These emissions are then added to your organization’s total Scope 1 emissions and included in sustainability reports. ### Reporting and Analysis * The calculated fugitive emissions are presented in detailed emission reports. * These reports can be analyzed to identify the sources of leaks and to develop mitigation strategies. ### Usage Tips * **Regular Maintenance:** Regular maintenance of HVAC and refrigeration systems can significantly reduce fugitive emissions. * **Accurate Data:** Ensure the use of accurate and up-to-date data in your calculations to guarantee reliable emission reporting. * **Equipment Upgrade:** Replacing old and inefficient equipment with new systems that use low-GWP refrigerants can greatly reduce fugitive emissions.
