# Approved ICR Methodologies This section is for methodologies that have successfully completed the International Carbon Registry (ICR) approval process. Each methodology is designed to meet the ICR methodology requirements following the ICR Methodology Approval Process, ensuring scientific integrity, transparency, and alignment with global best practices such as ISO 14064-2. Approved methodologies provide clear, transparent, and scientifically validated specifications for quantifying, monitoring, and reporting greenhouse gas (GHG) emission mitigations. In addition to approved ICR methodologies projects seeking registration in the ICR Program that comply with all ICR requirements may use all currently active methodologies from the Clean Development Mechanism.
