With support from the Government of Japan, Mitsubishi Corporation conducted a feasibility study in Vietnam in 2010 to assess the possibilities and prospects of bilateral cooperation mechanisms in the field of energy efficiency through the use of high performance air conditioners or inverter air conditioners.
Research results showed that CO2 emissions when using an inverter air conditioner reduced by 30 percent compared to the use of a non-inverter air conditioner. In addition, it recorded a 42 percent energy savings in those households installed with inverter air conditioners in Hanoi and a 36 percent in Ho Chi Minh City.
A widened use of inverter air conditioners can improve the efficiency of power consumption, helping Vietnam cut a significant amount of CO2 emissions. Therefore, this project will provide the prerequisite for the implementation of the Vietnam-Japan joint emission reduction certificate mechanism (JERCM) in the coming time.
According to General Director of Ministry of Natural Resources and Environment's Department of Meteorology, Hydrology and Climate Change Le Cong Thanh, a reduction in gas emissions is always a difficult problem for developing countries, including Vietnam. Therefore, the Ministry of Natural Resources and Environment continues to appreciate the support of international organizations to reduce greenhouse gas emissions in Vietnam. JERCM is also one of the important mechanisms to promote technologies to reduce greenhouse gas emissions.
JERCM has been developed with the purpose of facilitating the dissemination of technology, products, systems, services, and advanced low-carbon infrastructure; and the implementation of carbon reduction measures in order to contribute to the sustainable development of developing countries. Before JERCM, the clean development mechanism (CDM), a similar mechanism, was implemented in Vietnam, however, JERCM seems to be more advantageous than CDM. Specifically, CDM is a mechanism of cooperation between many different countries while JERCM is a mechanism based on a bilateral agreement between two nations. JERCM is deployed in the form that the developed countries will help developing countries with financial mechanisms for investment in economic development solutions with low carbon emissions.
Vietnam and Japan have conducted JERCM negotiations over nearly three years, and along with these negotiations, some of the JERCM projects have been carried out in Vietnam. "Mitsubishi is currently implementing several JERCM projects in Vietnam. Specifically, after examining Vietnam's energy efficiency potential, the Mitsubishi Group has extended support to businesses in the hospitality sector as an energy service company (ESCo). For example, it has installed a building energy management system (BEMS) at the Legend Hotel Saigon to control energy consumption there, which helped the hotel save about US$100,000 per year, plus also reducing 700 tonnes of CO2 emissions," Mitsubishi Group's senior consultant Nakamura Satoshi said.
"However, JERCM should need closer cooperation between the two sides, especially on methodological issues and a list of equipment and technology will be preferred," Deputy Director of Ministry of Industry and Trade's Science and Technology Department Nguyen Huy Hoan said.
According to Deputy Director of the Ministry of Natural Resources and Environment's International Cooperation Department Pham Van Tan, apart from methodological issues, a lack of JERCM consultant teams in Vietnam is also a major issue. To deploy JERCM effectively, these issues should be promptly addressed in order that both sides may soon come to a JERCM agreement./.
