RSB Japan FIT (Biomass) Certification

RSB’s Japan FIT (Biomass) Certification is for use by operators producing, procuring and importing biomass into Japan under Japan’s Feed in Tariff (FIT) system.

RSB’s Japan FIT (Biomass) Certification is applicable to operators producing, processing and trading biomass, including vegetable oils, residues and end-of-life products destined for use for power generation in Japan.

Currently, the following residues-based feedstocks are accepted under the RSB Japan FIT (Biomass) Certification:

  • palm kernel shell (PKS)
  • palm trunks

Example Claims

  • RSB Japan FIT Compliant Biomass
  • RSB Japan FIT Compliant Biomass


This regional adaptation of RSB’s sustainability standard has been developed to enable biomass producers and traders to demonstrate compliance with the sustainability requirements of RSB and to unlock access to Japan’s Feed in Tarif (FIT) system. FIT sets out a system of incentives for the production of renewable electricity in Japan which includes subsidies for the procurement of biomass which includes vegetable oils as well as various agricultural and industrial residues and end-of-life products.

Specific requirements for the certification of biomass – including for chain of custody – were published by Japan’s Ministry for Economy, Trade and Industry (METI) in April 2020.

The RSB Japan FIT standard incorporates these requirements so that products certified under this standard will be eligible under Japan’s FIT system.

RSB’s approach to sustainability is anchored in our 12 Principles for the sustainable production of biomass and products.



Risk-based approach: not every requirement applies to every producer and by completing the self-risk assessment and screening exercise during the certification process, your context-specific sustainability requirements will be set out.

Which documents apply to me?

Depending on the type of operator you are, you will only need to work with some of these documents. The specific sustainability requirements that apply within your operation will be clarified in your self-risk assessment as part of the RSB certification process.
