Refrigerant leak CO2 equivalent calculator

Enter the leaked mass in kilograms and the refrigerant global warming potential, and the calculator multiplies them using the standard mass-times-GWP relationship. It is useful for maintenance records, emissions inventories, incident reviews, and preliminary reporting checks. The calculation is deterministic, runs without a network lookup, and clearly rejects a negative leaked mass rather than producing a misleading negative emissions value.

Enter the leaked mass, not the installed charge by default

The first input is the amount of refrigerant that actually escaped, expressed in kilograms. If a system contains a larger installed charge but only part of it was lost, enter the lost portion unless your assessment assumes a complete release. For example, a unit charged with ten kilograms that lost one quarter of its contents has a leaked mass of 2.5 kilograms. Maintenance logs, recovery-cylinder measurements, or the difference between pre-service and post-service quantities may help establish this value. Keep the measurement basis with your record because the calculator evaluates the number supplied; it does not estimate leakage from pressure, operating time, equipment type, or charge capacity. Zero is valid and produces zero carbon dioxide equivalent. A negative leaked mass is not physically meaningful for an emissions event, so the calculation rejects it with an input error. If recovered refrigerant must be accounted for separately, calculate or document that inventory adjustment before entering the net leaked quantity here, following the rules applicable to your report.

Use the correct global warming potential

Global warming potential, usually abbreviated GWP, is a dimensionless factor that compares the warming effect of a refrigerant with the effect of the same mass of carbon dioxide over a defined time horizon. Enter the factor required by the inventory method, regulation, contract, or reporting framework you are following. The calculator deliberately does not select a factor from a refrigerant name because published values can differ by assessment report, time horizon, blend treatment, and reporting rule. Recording the source and version of the GWP beside the result makes the calculation reproducible during an audit. The factor must be a finite, nonnegative number. Do not enter a percentage, carbon-equivalent value, or a factor that has already been multiplied by mass. For a refrigerant blend, use the GWP value prescribed for that blend rather than informally averaging its components. When comparing records across years or organizations, confirm that they use the same GWP basis before treating differences in calculated emissions as operational changes.

Interpret kilograms and metric tonnes of CO2 equivalent

The calculation multiplies leaked mass in kilograms by the selected global warming potential. The primary result is kilograms of carbon dioxide equivalent, and the calculator also divides that value by one thousand to report metric tonnes of carbon dioxide equivalent. These two outputs describe the same climate impact at different scales; they must not be added together. Retain enough precision for your reporting procedure, especially when many small leaks will later be summed, and apply any mandated rounding only at the appropriate final stage. This result is a direct emissions conversion, not a full life-cycle assessment. It excludes electricity consumption, manufacturing, transport, servicing activity, avoided emissions from recovery, and any leakage that was not included in the entered mass. It also does not determine compliance thresholds or filing obligations. Use the output as a transparent arithmetic component within the relevant inventory or maintenance process, together with the leak date, equipment identity, refrigerant designation, mass evidence, GWP source, and any required review or approval.
