Overview of Specifications


In order to achieve its goal of carbon neutrality by 2050, in February 2023, the Japanese government announced the introduction of an "emissions trading system" as part of the carbon pricing system design in its "Basic Policy for the Realization of GX." Trial trading is scheduled to begin in FY2023 and full-scale operation in FY2026, so as part of this, there are expectations for a carbon credit market to be created in FY2023.
Based on the knowledge and market operation experience gained from the "Technical Demonstration Project for Carbon Credit Market" commissioned by the Ministry of Economy, Trade and Industry (METI) in FY2022, Tokyo Stock Exchange, Inc. (TSE) has established a carbon credit market.

Note: Carbon Credit Market is different from Tokyo Stock Exchange's financial instruments markets such as cash equity market, etc.
