Alongside the accelerated growth in populations and urbanisation in Asia are the growing problems of road traffic, solid waste,s and air and water pollution. Torrential rains, flooding, landslides and droughts are intensifying, all of which are considered impacts of global warming. Present estimates show that cities count for more than 70% of global CO2 emissions, and that by 2050, Asia will be responsible for half of global energy consumption and CO2 emissions. Sustainable, low-carbon development of Asian cities is therefore an urgent and global challenge.
With the above circumstances in mind, the Ministry of the Environment, Japan (MOEJ) implements support for low-carbon city development in developing countries through city-to-city collaboration, to enhance and promote decarbonisation. Entitled “City-to-City Collaboration for Low Carbon Society” (hereinafter “City-to-City Collaboration Programme”), the support programme involves partnering up cities in developing countries with those cities in Japan, which that are experienced in sustainable, low-carbon development and city management, in order to effectively and efficiently bring about low-carbon cities. Any Ppromising low-carbon technologies that are identified can then make use of the MOEJ’s financing programme financial support scheme for Joint Crediting Mechanisms (JCM), which contributes to greenhouse gas reduction both in the partner country and in Japan. Since cities are home to various types of infrastructure, advanced low-carbon technology, products and systems can be used to promote low-carbon development and create co-benefits for climate mitigation and improved urban environments and services.
This guidebook was prepared for city officials and the private sectors within cities in developing countries interested in the City-to-City Collaboration Programme.
