We are very pleased on the occasion of the 30th Montreal Protocol Anniversary International Ozone Day, to present you with our latest application – The GWP-ODP Calculator.

We very much hope you will find this application useful. It was designed for you as Montreal Protocol National Ozone Unit staff. The application allows 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.
    • Full instructions are included in the app.

The app is available for free from the Google Playstore. (iOS version available very soon). Search for “GWP ODP CALC” in the Playstore to install.

Download and start using it now!!!
