• Joint research and studies for model projects are underway with China and Indonesia, following the respective ministerial agreements in 2007. Continuous cooperation for a co-benefits approach were agreed between Japan and China in April 2011, and between Japan and Indonesia in July 2015. Capacity building, feasibility study for mitigating air pollution and GHG reduction have been conducted in China. In Indonesia, capacity building and studies including demonstration for the co-benefits type waste water treatment have been conducted.
• In Mongolia, demonstration project for improving air pollution and GHG reduction have been conducted with capacity building since 2014.

2. Multilateral cooperation

• The "Asian Co-benefits Partnership" was launched in November 2010, at the "Better Air Quality 2010 (BAQ2010)" conference in Singapore. The objective of the partnership is to mainstream a co-benefits approach and promote co-benefits type projects in Asia. The partnership has regular conferences, provides information by their website and publishes the "Co-benefits white paper" for further promotion of a co-benefits approach.
• Support to the research project to improve capacity building for policy-making and implementation in Asian developing countries, promoting wastewater management and water quality conservation policies considering low carbonization, by providing necessary information and policy evaluation methods.

3. Development of evaluation methodology

• A Manual for Quantitative Evaluation of Co-Benefits Approach to Climate Change Projects was developed in FY 2009. Efforts are underway to disseminate the methodology for quantitative evaluation of the accompanying environmental control benefits (co-benefits) of CDM and other project implementations.
