The Urban Research Center at Kyushu University, led by Shunsuke Managi, CEO of aiESG, is launching a new initiative in collaboration with Calyx Global, the world’s largest carbon credit rating agency based in the United States, to enhance the credibility of the carbon credit market. In response to the widespread circulation of low-quality credits, this initiative aims to combine Calyx Global’s rigorous credit rating system with Kyushu University’s academic expertise to improve the visibility of high-quality carbon credits and elevate investment practices through ESG evaluation. The project also involves collaboration with the Natural Capital Credit Consortium (NCCC), promoting decarbonization investments that prioritize natural capital and social value. Through joint research using approximately 1,000 credit rating data points, the initiative seeks to clarify the impact of credit quality on corporate evaluations and investment behavior, ultimately enhancing market transparency and contributing to a decarbonized society.

Calyx Global is a company that assesses the quality of carbon credits. It aims to increase the credibility and transparency of the carbon credit market.

In this initiative, aiESG will use natural capital such as agricultural land, forest area, and air quality based on its own global statistical database to index ESG-related risks and natural regeneration effects, and support the creation of high-quality credits and the advancement of evaluation methods. Through these efforts, we aim to increase market transparency and promote the establishment of a foundation for decarbonized investment that emphasizes natural capital and social value.

The following media outlets have introduced this initiative. Please take a moment to read them.
