Green Gold Label (GGL) is an international certification programme for sustainable biomass. Established in 2002, GGL is amongst the earliest biomass certification schemes, having established a unique track record in the certification and tracking & tracing of the complete supply chain from production, processing, transport to final use of biomass products, including wood chips, pellets, and biofuels (including PKS), with a focus on sustainability and environmental protection.

The GGL program sets standards for the production of biomass and provides assurance to buyers that the products they purchase are produced in a sustainable manner. The program aims to promote the use of sustainable biomass as a renewable energy source and to reduce the impact of biomass production on the environment. The Green Gold Label certification is an important tool for promoting sustainable biomass production and use, and helps to ensure that biomass products are produced in a responsible and sustainable manner.

CARSURIN is the sole holder of KAN accreditation for the GGL certification scheme (biomass category 1-5, inclusive). This is particularly applicable to exports of Palm Kernel Shell (PKS) to Japan.

To promote the use of sustainable biomass, the Japanese government has established the Renewable Energy Certificate (REC) system, setting out a number of regulations and requirements for biomass certification, including the use of renewable energy sources.

This system provides certificates for the generation of renewable energy and allows for the trade of these certificates between buyers and sellers. To obtain an REC, a generator of renewable energy must meet certain requirements, including the use of sustainable biomass, as evidenced by GGL certification.

A successful GGL certification will lead to the entity being accepted as a source of biogenic waste/residues (biomass category 5) under the GGL scheme requirements for the Japanese market and ensures that category 5 biomass delivered to the Japanese market are in compliance with the METI (Ministry of Economy, Trade and Industry) FIT (Feed in Tariff) scheme.

By requiring this certification, the Japanese government aims to support the development of a low-carbon energy sector that reduces greenhouse gas emissions and contributes to a more sustainable future.

Whether your position in the supply chain is as producer or trader, CARSURIN is uniquely placed to assure your compliance and reduce your risk in the supply of biomass products.
