    FIT non-fossil certificates are the most widely traded and standardized renewable energy certificates in Japan, and have the value of renewable energy sources such as solar, wind, small hydro, geothermal, and biomass.
    Tracked non-fossil certificates disclose information about where and how the power was generated.
    By obtaining non-fossil certificates, your company can demonstrate that your electricity is generated from renewable sources.
    The certificates can be applied to RE100, CDP, and the Act on Promotion of Global Warming Countermeasures.

    J-Credits are carbon credits issued under a national certification system in Japan. The amount of CO2 and other emissions reduced through the introduction of energy-saving equipment and the use of renewable energy, as well as the amount of CO2 and other emissions absorbed through appropriate forest management, can be certified and issued as carbon credits.
    The credits can be used for SBT, CDP*, RE100, the Act on Promotion of Global Warming Countermeasures, and the Act on the Rational Use of Energy. They can also be used for short-term, spot carbon offsets, such as for green events.

    • * may depend on the type of J-credit


    Can be transferred between companies or shared with subsidiaries

    No expiration date

    Voluntary credit

    Voluntary credits are carbon credits initiated by private organizations such as companies and NGOs. They include not only renewable energy, but also carbon credits generated from activities to protect terrestrial ecosystems such as marine ecosystems and forests.
