Switching Supermarkets from Using Halogenated to Natural Refrigerants

Objective and activities

The aim of the project was to pilot the conversion of the air-conditioning systems in two supermarkets owned by the Pick n Pay chain from fluorinated refrigerants to natural, environmentally compatible, energy-saving refrigerant technology. At the beginning, the project supported the supermarket chain in acquiring tradable carbon credits for future emissions reductions via the Clean Development Mechanism (CDM) as this was supposed to gain significant co-financing opportunities for investment in new systems. In the end, this idea was abolished due to low CER prices on one hand, but rather due to high and significant savings through energy efficiency measures. This savings were used to refinance the conversion of more supermarkets.
