The first and second Global Good Practice Analyses (GPA 1.0 and 2.0) were carried out in 2014 and 2015 in a collaborative effort between Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the UNDP Low Emission Capacity Building Programme (LECB), under the aegis of the International Partnership on Mitigation and MRV. After the introduction of the Enhanced Transparency Framework with the Paris Agreement in 2015, the International Partnership on Mitigation and MRV was renamed in Partnership on Transparency in the Paris Agreement (PATPA), which continues to support the exchange of good practices, joint learning and policy dialogue between Policy makers and practitioners. In 2018, PATPA, the IKI NDC Support Cluster, the UNDP NDC Support Programme, the LEDS Global Partnership (LEDS GP) and the NDC Partnership established the Good Practice Database (GPD), which serves as a central hub for case studies on learning and leadership in climate action and NDC implementation. The case studies developed as part of GPA 1.0 and GPA 2.0 have been merged into the GPD.

In continuation of the successful GPA 1.0 and 2.0, this analysis of new case studies for the GPD enhances and expands the existing repository of good practice examples with a focus on NDC implementation. A project team led by adelphi and comprising NewClimate Institute, The Energy and Resources Institute (TERI), Libélula and Centre de Suivi Ecologique (CSE) was asked to identify and examine a new selection of cases which demonstrate how mitigation and adaptation action can be effectively designed and implemented across different country contexts. The objective of this summary report is to synthesise the key findings from these new cases, highlighting key elements of good practice and success factors that appear across multiple cases and can be considered important building blocks for designing and implementing ambitious climate action. The findings of the GPD Summary Report confirm and corroborate central outcomes of earlier GPA Summary Reports and reflect conclusions from the briefing Fostering Success Factors for NDC Implementation1, published in early 2019.
