The teams at International Biochar Initiative and HAMERKOP have been hard at work updating the guide with the latest information on the carbon removal market, standards and methodologies, and more since the first edition was released in 2024.

The digital guide provides a roadmap for biochar producers, investors, and stakeholders keen on understanding the intricacies of biochar carbon removal certification. Readers gain a clear overview of the various methodologies established by leading certification standards, with the goal of offering practical insights and comparisons to assist producers and investors in selecting the most appropriate approach for their specific biochar projects.

Some of the main 2025 updates include: 

• A new and improved section covering MRV, permanence, and more 

• Updated pricing information for each biochar certification standard and detailed step-by-step guides to help you choose the right methodology for your project

• An addition of the Isometric biochar methodology to the overall matrix 

This guidebook aims to inform the design of agricultural carbon projects and to support project developers in navigating key project development issues, drawing on lessons learnt from a pilot project; the Western Kenya Soil Carbon Project (WKCP) as well as feasibility studies in India and Madagascar.
