About Us

日本語 English

We aim to promote sound climate financing mechanisms for natural capital

We combine remote sensing and causal inference techniques to assess the effectiveness of nature conservation projects with a high degree of accuracy. We also collaborate with national and international research and public institutions to incorporate cutting-edge knowledge on natural capital.

Credo

01. At war against greenwashing

  • We pledge to remain alert to prevent unintended involvement in greenwashing.
  • We will do our utmost to ensure that funds are channelled into natural capital without being complicit in the creation of junk carbon credits.

02. In search of new knowledge

  • We continuously put in our best effort to stay current with the findings of academic research in our daily work.
  • Knowledge can easily become out-of-date in our rapidly changing world and it is extremely crucial to regularly review and renew our understanding.

03. On the shoulder of giants

  • Our operations are supported by Earth observation satellites such as Sentinel and Landsat, and a wealth of previous research in forest science and ecology.
  • We aim to respect prior research and use that wisdom to build valuable services.

04. Next to leading institutions

  • The degradation of natural resources, such as through deforestation, is caused by a complex array of factors that we cannot tackle on our own and without external help.
  • We strive for collaboration alongside both domestic and overseas research institutes and business companies.
