The seminar is part of a cooperation program linking HCM City and Osaka.
The low-carbon city development programme between HCM City and Osaka has already resulted in a memorandum of understanding covering energy efficiency, public transport, sustainable water management, solid waste treatment, urban and industrial waste treatment, urban planning, clean water supply, irrigation, flood prevention, and applying information technology (IT) managing harmful waste.
The two cities have also collaborated on research into recycling energy via solid waste treatment.
Dao Anh Kiet, Director of the HCM City Department of Natural Resources and Environment, noted the programme is helping HCM City minimise its carbon emissions.
Seminar delegates used the lens of low carbon emissions to consider issues in water, waste water, transport, energy, and food.
They also discussed innovations in fuel, public transportation infrastructure upgrades, promoting electric motorbikes, powering electricity using waste, and environmentally friendly industrial waste water treatment in HCM City.
A Japanese Ministry of Environment representative introduced HCM City authorities to the programmes the ministry runs that encourage and support low carbon emission city development in Asia.
