Abstract

This report examines the risks and opportunities of using carbon crediting mechanisms to fund the protection and restoration of coastal ecosystems. It evaluates seven projects registered in the voluntary carbon market, focusing on key challenges related to integrity risks such as additionality, quantification, permanence, safeguards, and double counting. Despite uncertainties in measurement methods, the report highlights that projects tend to adopt conservative estimates of carbon removals. Aimed at stakeholders in carbon crediting programmes, policymakers, and researchers, it emphasizes the need for improved data collection and peer-to-peer learning to enhance project outcomes.
