Recent LinkedIn posts by Tristan Springer (Valorize Systems) and David Hughes (PlantVillage+) raise an important question for the biochar carbon removal community: Are current MRV requirements always grounded in empirical evidence, or are some based on precautionary assumptions that may unnecessarily constrain market development?

Springer points to examples where certain registry requirements for tracking retail biochar products to their final end use may be technically feasible but commercially impractical. He argues that while permanence is critical, MRV requirements ultimately shape which end markets remain viable.

Building on that discussion, Hughes draws a historical analogy to the evolution of measurement standards. Before modern metrology, commerce relied on locally defined units that functioned but were largely authority-based rather than scientifically standardized. He suggests that carbon markets face a similar challenge when registry rules establish reversal risks without clearly presenting the empirical basis behind those assumptions.

Neither author questions the importance of permanence or the role of registries. Rather, both advocate for greater transparency and proportionality: if a reversal scenario is supported by evidence, the corresponding safeguards are justified; if the risk is only hypothetical, the monitoring burden should reflect its actual likelihood.

These perspectives raise an important question for our community:

How should the biochar industry balance scientific rigor, practical implementation, and commercial scalability while maintaining confidence in carbon removal credits?
