The NDC Partnership launched its Climate Action Enhancement Package (CAEP) in 2016 to support interested countries in revising, implementing and re-developing their NDCs. CCA plays an important role in this. By mid-2020, more than 65 countries had already received support from this programme. Some countries, such as the Dominican Republic, Peru, Uganda and Zimbabwe, have started to get their subnational levels of government heavily involved in these efforts, and Rwanda is considered a particularly successful example.
