Tracking Nationally Determined Contributions (NDC) is a mandatory element of the Biennial Transparency Report (BTR) under Section III of the Modalities, Procedures, and Guidelines (MPGs). It is a key mechanism for assessing progress on climate commitments under the Paris Agreement; and ensuring that countries provide clear, consistent, and transparent information on NDC implementation and achievement.

The tracking process enhances accountability, supports global stocktaking and identifies gaps in climate action. By standardizing reporting through the Common Tabular Format (CTF), the MPGs also promote comparability and reliability in tracking emissions reduction and adaptation goals.

The NDC Tracking Tool supports countries in monitoring progress toward implementing and achieving their NDCs. It compares planned versus implemented mitigation and adaptation actions across all sectors. It also estimates the resulting greenhouse gas (GHG) reductions, measured against sectoral or national baselines and NDC targets.

The tool provides a modular, multi-sectoral approach to support the collection of information needed to complete the CTFs for electronic reporting, as required by the MPGs. It is designed to help countries review their progress in NDC implementation and inform future NDC enhancement planning.
