Regreener compares carbon credit standards for corporate buyers in 2026

Regreener has published a guide comparing key carbon credit standards, including Verra, Gold Standard, Plan Vivo, Puro.earth, and Isometric, for corporate buyers in 2026. The guide highlights that the choice of standard depends on the specific climate claim a company aims to make, distinguishing between avoidance and removal credits, permanence, and stakeholder reporting needs. It outlines four critical factors for evaluating standards: additionality, permanence and durability, MRV (measurement, reporting and verification), and co-benefits. The analysis notes that while Verra dominates in volume and project type breadth, its quality varies, necessitating project-level due diligence.
