Continuously improving the GGL certification scheme

The GGL certification scheme continues to evolve in response to changing legislation, scientific insights and stakeholder feedback.This page provides an overview of topics that are currently under development or scheduled for future updates. By publishing these topics, GGL promotes transparency and keeps stakeholders informed about planned improvements to the certification scheme.

Introduction

Open development through transparency

Maintaining a robust and practical certification scheme requires continuous evaluation and improvement.

Pending Topics identify areas where additional guidance, new requirements or further assessment is being developed. They provide visibility into the ongoing evolution of the GGL certification scheme while ensuring that changes are introduced through a structured and transparent process.

Current Scheme Developments

Regulatory Developments

Updates related to evolving legislation, government policies and market requirements that may affect the GGL certification scheme.

Under assessmentLast updated · July 2026

RED II / RED III Recognition

GGL is progressing the recognition of its RED Module under the European Renewable Energy Directive (RED II/III). The module has been developed to align with the core GGL certification standards while incorporating the latest European legislation and implementing regulations. Once recognised, it will support certification of all solid biomass and address additional regulatory requirements, including the European Deforestation Regulation (EUDR).

Scheme Development

These topics concern the continuous improvement of the certification scheme itself.

Documentation Updates & Edits (6 July 2026)

Minor updates and clarifications have been published across several GGL documents on July 6 2026. These include improvements to FIT/FIP requirements, GHG default values, chain-of-custody requirements, moisture measurement provisions and supporting documentation. Stakeholders are invited to review the published versions and provide feedback before the documents become adopted.

You can find the new documents on our website with the Published status.

Some documents have been edited and updated, which GGL and its Advisory Council consider minor. However, for stakeholders under FIT/FIP, these edits and updates will have implications, such as:

  • Added the possibility for power companies to mix GGL Biomass with other biomass at the last and final inventory before conversion (Instruction B.0 - FIT/FIP Module);
  • Stricter requirements for integrating biomass from Endorsed schemes into the GGL Chain of custody, to safeguard the integrity of GGL Biomass (Instruction B.1 - FIT/FIP Endorsed schemes);
  • Updated the default values for Lifecycle GHG emission calculations (Instruction B.2 - FIT/FIP GHG emissions) with references to the Guidance in Japanese and a preliminary English translation; and
  • New possibilities for GGL Participants, under certain conditions, to use calibrated equipment for moisture measurements (GGLS1 - Chain of custody criteria).

After integrating feedback, the updated documents will become Adopted and valid as of 7 September 2026.

Newly PUBLISHED documents can be recognized by their status showing a pen icon!

All documents contain a Change log, for easy referencing to previous versions.

A document with version v1-0 that has Major changes receives a new version v2-0 while only with Minor changes the new version is v1-1.

Certification Bodies

Temporary measureCategory · Board resolutionLast updated · July 2026

Temporary Suspension Applications New Certification Bodies

Applications from new Certification Bodies are temporarily suspended until October 1st 2026, while GGL focuses on supporting the transition of existing Certification Bodies to the updated certification scheme. During this period, training, accreditation updates and harmonisation activities are being carried out to ensure consistent implementation of the revised documentation. Applications will reopen after the temporary suspension period.

How Pending Topics are managed

A structured approach to continuous improvement

Each Pending Topic follows a defined review and decision-making process.

Depending on the nature of the topic, GGL may conduct technical assessments, engage stakeholders, consult Certification Bodies or monitor regulatory developments before incorporating changes into the certification scheme.

Once adopted, updates are published through revised documentation and communicated to stakeholders.

Keeping stakeholders informed

Transparency throughout the development process

Publishing Pending Topics helps stakeholders understand which subjects are under consideration and how the certification scheme continues to evolve.

This open approach supports consistent implementation, encourages stakeholder engagement and contributes to confidence in the ongoing development of the GGL certification scheme.
