The duty to know: monitoring, reporting and verification as an obligation of due diligence in the legal protection of blue carbon ecosystems
Blue carbon ecosystems—mangroves, tidal marshes, and seagrass meadows—are increasingly central to national climate strategies, yet their legal protection under international law requires further clarification. Emerging jurisprudence highlights a critical “epistemic conditionality”: States are obligated to *know* the condition of these ecosystems, and protection hinges on their ability to provide legally verifiable proof. This article analyzes this obligation, demonstrating that monitoring, reporting, and verification (MRV) extends beyond climate policy, fulfilling binding duties under the United Nations Convention on the Law of the Sea.
