Climate Mitigation

Various International Approaches to Climate Change Mitigation Outreach

Based on the Nationally Determined Contributions (NDCs) submitted by countries under the Paris Agreement, OECC has been proactively engaged in research for planning and implementation, support for the formulation of national laws and regulations, and support for climate change measures among cities. In addition, OECC has been focusing on its support for the establishment of GHG measurement, reporting and verification system (MRV) in response to the growing need for assistance related to national reporting and GHG inventory preparation scheduled for submission in 2024 as stipulated in Article 13 of the Paris Agreement. Furthermore, with regard to the transparency of GHG emissions of businesses in the private sector, OECC is providing support for establishing and operationalizing transparency systems and improving access to Environmental Social and Governance (ESG) investments. In the future, we will also promote efforts to visualize GHG emissions through the supply chain, which involves emissions calculation and reporting (including Scope 3) from the perspective of promoting GHG emission reductions across the world.


Support for the Establishment and Implementation of the Bangkok Metropolitan Administration’s Climate Change Master Plan and Verification of Target Achievement

OECC has been engaged in capacity-building support for the establishment and implementation of a Climate Change Master Plan for the Bangkok Metropolitan Administration (BMA) of Thailand since 2009. Through a Japan International Cooperation Agency (JICA) technical cooperation project, the BMA was the first to establish and implement a full-scale master plan, resulting in a 24% reduction, far exceeding the 2020 target. The original goal was to reduce 13.57% GHG emissions compared to Business as usual (BAU), which means no mitigation measures are taken against Climate Change by 2020. We also cooperated with long-term experts dispatched to the BMA and participated in supporting the development of a new Master Plan on Climate Change for the period 2020~2030, taking into account net zero emissions in 2050. Furthermore, through the Ministry of the Environment, Japan’s Intercity Cooperation Program, we are enhancing our efforts to introduce and deploy Japan’s decarbonization technologies by supporting the partnership between the Bangkok Metropolitan Administration and the City of Yokohama.

Improving Transparency of GHG Emissions by Companies in ASEAN

OECC is the secretariat of the Partnership to Strengthen Transparency for co-Innovation (PaSTI) project, led by the Ministry of Environment, Japan since 2017, and has been supporting the improvement of transparency in GHG emissions to achieve net zero emissions under the Paris Agreement. Specifically, we support the establishment of GHG emissions calculation and reporting systems based on the needs of governments and companies in Vietnam, the Philippines and Thailand, as well as the promotion of ESG finance, which can function as an incentive for companies to report their GHG emissions. We are also supporting the establishment of a guideline that outlines the steps to be taken by each country to establish a corporate GHG emissions calculation and reporting system. This is in addition to the establishment of an information platform on the efforts of each country, utilizing the Japan-ASEAN Integration Fund (JAIF), an international fund, thereby helping to improve the transparency of GHG emissions in the ASEAN region as a whole. This is one of the ways we are contributing to the transparency of GHG emissions in the ASEAN region.
