At a meeting of the joint committee for the Joint Crediting Mechanism (JCM) between Japan and Cambodia, Japan's Ministry of the Environment announced Feb 28, 2020, that it has decided to issue credits for the first time in Cambodia.

The amount of JCM credits is 181t-CO2, of which the Japanese government will obtain 92t-CO2.

This time, the ministry decided to issue the JCM credits for its project for the "Introduction of Ultra-lightweight Solar Power Generation System to International School," which was carried out as the ministry's JCM facility aid project for fiscal 2015. Asian Gateway Corp (Chiyoda-ku, Tokyo) and International School of Phnom Penh are responsible for the project on Japan's and Cambodia's sides, respectively.

In the project, 200kW of ultra-lightweight solar panels were set up on the roof of an international school located in "ING City," a satellite city located to the south of Phnom Penh. All the electricity generated with the panels is consumed in house. It is expected to reduce greenhouse gas emissions by 104t-CO2 per year.

The solar panel to be introduced uses chemically-reinforced special glass as cover glass. As a result, its weight is 50% lighter than the weight of the previous product. Structures in Cambodia generally have a low strength. So, the technology of the ultra-lightweight solar panel is expected to be widely used in developing countries.

Japan's JCM partners are Mongolia, Bangladesh, Ethiopia, Kenya, the Maldives, Vietnam, Laos, Indonesia, Costa Rica, Palau, Cambodia, Mexico, Saudi Arabia, Chile, Myanmar, Thailand and the Philippines (17 countries). Through the projects of the Japanese government that are carried out within a budget secured for every fiscal year, it is expected that CO2 emissions will be reduced (or absorbed) by 50,000,000-100,000,000t in total by fiscal 2030.
