Training activities of the project "Supporting the design of sustainable development policies with policy modelling tools" were completed for Nicaragua, in Managua, on 6-9 July 2015. Workshops were organized for training government officials in the use of an economy-wide model and an integrated energy system to assess policies for sustainable development. Trainees are now well equipped to work on a number of policy notes, covering issues of relevance for sustainable development, which will be presented to and discussed with high-level policymakers in October 2015.
