The ADB project is supporting the expansion of “green” bus services in the People’s Republic of China, an initiative that will benefit low-income commuters, improve air quality and reduce GHG emissions. The initiative is in line with the $175 billion commitment made at the June 2012 UN Conference on Sustainable Development (UNCSD, or Rio+20) by multilateral development banks to improve transport in developing countries between 2012 and 2022.
