Assessment of HCFCs use in Mexico in the cooling and air conditioning sector -2008
HCFCs, used as an alternative to replace CFCs, the main contributors to the depletion of the ozone layer, also have negative effects on the ozone layer; in addition to their high potential for global warming, they contribute significantly to enhancing the greenhouse effect. That is why, in 2007 the countries that signed the Montreal Protocol agreed to their global elimination, both production and consumption; for developing countries the deadline is set for the year 2030. In this study, the Mario Molina Center evaluated technological alternatives in order to eliminate the use of HCFCs in cooling and air conditioning systems in Mexico. As well as in the international market, Mexico maintains a high consumption of HCFC-22 (95% in cooling and air conditioning, due to their low cost). This is a result of the economic incentive generated amongst refrigerant producers to destroy HFC-23, a byproduct of the first, through the sale of carbon bonds encouraged by the Kyoto Protocol. This incentive can be reversed if its removal in the process becomes
Additionally, we found that replacing HCFCs with other alternative gases brings direct economic benefits, since these mostly require lower energy demand. According to the economic benefits and available technologies in the Mexican market, the Mario Molina Center identified that Mexico has the ability to accelerate the removal of these compounds by the year 2020.
