The Swiss standards organization Gold Standard has published its first carbon dioxide removal methodology for biochar, titled Production and Application for the Removal of Carbon via Biochar. The framework establishes standardized certification criteria for crediting durable carbon removals across operations of varying scale. The structure accommodates artisanal kiln networks alongside large industrial facilities while maintaining consistent rules for durability, eligibility, and net accounting. Under this standard, projects earn credits exclusively for quantified carbon removals rather than emissions avoided through alternative biomass uses.

The biochar sector has historically faced significant challenges regarding standardization, additionality, and the inclusion of distributed producers without sacrificing environmental integrity. Manual and semi-mechanized operators frequently encounter prohibitive verification costs and administrative barriers, preventing capital deployment to smallholder communities. Conversely, industrial installations require rigorous life cycle emissions assessments and continuous monitoring to guard against over-crediting and non-additional feedstock diversions. Standardizing permanence across diverse soil and non-soil application sites has also presented major technical obstacles for carbon registries.

Gold Standard resolves these operational barriers by introducing a three-track compliance architecture matched to processing capacity. Track 1 governs manual and semi-manual kilns processing under one dry tonne daily through aggregators, utilizing a digital chain of custody and annual caps of 60,000 tonnes of carbon dioxide equivalent. Track 2 applies to mechanized units handling between one and 15 tonnes per day with direct feedstock weighing. Track 3 covers industrial plants exceeding 15 tonnes per day, mandating continuous stack monitoring and batch laboratory analyses. Credited removals are calculated on a 200-year storage baseline, require full life-cycle emissions deductions, and enforce a strict threshold where projects must store at least five units of carbon dioxide for every unit emitted.

The methodology provides project developers with clear compliance routes while excluding non-permanent outcomes such as fuel combustion and landfill disposal. Producers in Least Developed Countries and Small Island Developing States benefit from deemed additionality in distributed configurations, accelerating local climate finance. Requiring minimum buffer deductions of 2.5 percent ensures conservative crediting while protecting buyer confidence. By standardizing durable removals across distinct operating tiers, the framework enables broad market participation and strengthens the integrity of carbon markets.
