This application was designed for Montreal Protocol National Ozone Units and should also be useful for other related stakeholders. It is intended to help in understanding and data reporting under the Montreal Protocol. The application allow you to easily convert ODP, CO2-eq and metric quantities of refrigerants and other chemicals.
  • Helps in understanding and reporting under the Montreal Protocol (and for your future commitments under the Kigali Amendment)
  • The calculator will automatically perform the conversion between metric tonnes, ODP tonnes and/or CO2-equivalent tonnes (or kg) and display the corresponding converted values
  • The app includes both single component substances and refrigerant blends
  • The components of a mixture and their relative proportions (metric, ODP, CO2-eq) are also displayed.
