Soil Carbon Credits Gain Benchmark Backing

Independent standard boosts credibility, raising data demands and reshaping finance for regenerative agriculture  

12 Feb 2026

The voluntary carbon market has tightened its standards, and soil carbon developers are moving to meet them.

The Integrity Council for the Voluntary Carbon Market (ICVCM) has approved the US Soil Enrichment Protocol under its Core Carbon Principles (CCP) label, giving buyers greater assurance over soil-based carbon credits. The CCP framework is an independent benchmark for high-integrity credits and, while voluntary, is increasingly treated as a de facto standard by large corporate purchasers.

The decision is influencing how regenerative agriculture projects are financed, verified and marketed across North America.

Soil carbon credits have long faced questions over how accurately carbon gains can be measured and how permanent they are. Under the CCP label, developers must demonstrate that removals are real and durable, undergo independent third-party verification and guard against double counting. The higher bar is intended to address concerns that have weighed on the sector.

Indigo Ag, whose soil carbon programme aligns with the approved protocol, described the decision as validation for regenerative agriculture. Market analysts say clearer standards could support larger and longer-term offtake agreements, particularly from multinational buyers.

Microsoft, one of the most active corporate purchasers of carbon removal credits, has prioritised science-based and transparent projects. Independent benchmarks such as the CCP framework are designed to help companies navigate investor scrutiny and climate disclosure requirements. Credits that meet recognised thresholds are increasingly favoured over those without external validation.

The shift brings operational challenges. Meeting stricter criteria requires more extensive soil sampling, improved data systems and tighter oversight. Smaller project developers may face higher compliance costs, and farmers could encounter greater reporting demands.

In the near term, supply may tighten as projects adjust to the new requirements. Over time, however, proponents argue that stronger screening could improve buyer confidence and support more stable pricing.

The broader effect is to move soil carbon towards a more formalised phase of development. With independent benchmarks shaping procurement decisions and institutional demand rising, soil-based removals are becoming a more established part of North America’s voluntary climate market.
