A carbon dioxide-focused curriculum for community college and trade school HVAC and refrigeration programs is under development to address a shortage of technicians trained to install and service natural refrigerant technologies.

CO2 is considered a climate-friendly alternative to traditional hydrofluorocarbon refrigerants but its deployment Source: NASRCSource: NASRCin supermarkets and other facilities has been hindered by high initial costs, lack of performance data and a shortage of technicians trained in natural refrigerants. Limited training opportunities and resources pertinent to this emerging technology prompted the North American Sustainable Refrigeration Council (NASRC), a nonprofit group advocating adoption of natural refrigerants, and ESCO Group, an educational and training body for the HVAC and refrigeration industry, to collaborate on the creation of a CO2 curriculum.

A committee composed of CO2 experts, training specialists, contractors and technicians, equipment manufacturers and school representatives are now devising the course content, which is scheduled to be completed and made available to educational facilities in 2021.
