Efficient Nationally Determined Contribution (NDC) tracking systems are necessary for demonstrating and reporting progress. Existing Measurement, Reporting and Verification (MRV) systems must be strengthened to this end. The project provided partner countries with tools and resources to track the implementation and impact of their NDCs and underlying policies. It identified further mitigation opportunities for future NDCs and supports development of Long-term Low Emission Development Strategies (LTS). Countries could implement the MRV requirements of the Paris Agreement and report their results on international levels. Partner countries thus became regional and global centres of excellence for communicating successful MRV methods, enhanced NDCs and new LTS. Lessons learned fed into the United Nations Framework Convention on Climate Change (UNFCCC) to develop of a robust system to track and report progress of NDC mitigation measures. The project also supported the NDC Partnership.
