WhatGas?

WhatGas? is a comprehensive mobile application developed by the UN Environment Programme (UNEP) OzonAction designed to assist stakeholders such as customs officers, Montreal Protocol National Ozone Officers, and refrigeration technicians. It serves as an easy-to-use reference for identifying refrigerant gases including ozone depleting substances (ODS), hydrofluorocarbons (HFCs), and their alternatives.

The app offers detailed chemical information like names, formulas, trade names, and key identifiers including CAS numbers and ASHRAE designations. It incorporates updated scientific data on ozone depletion potentials (ODP) and global warming potentials (GWP), adhering to the Montreal Protocol and IPCC reports. Features include support for new refrigerant mixtures, the latest 2022 harmonized customs codes, hazard details, and multilingual support in French and Spanish. WhatGas? facilitates compliance with environmental regulations by providing quick, on-the-go reference data to improve fieldwork accuracy and efficiency in managing refrigerants globally.
