ADEME has already committed to providing Project Managers and an operational guide for those public authorities who have already engaged in a PCET (Regional Climate and Energy Plan) process, with a view to helping these authorities to monitor and evaluate their approach. The guide sets out the key principles of the evaluation process, as well as practical feedback to illustrate the methodological elements. This guide is an additional reference framework. It is intended to give public authorities the tools and guidance they need to evaluate their PCET effectively, irrespective of their existing level of knowledge and resources, and the progress of their PCET. This practical, user-friendly guide approaches evaluation in a holistic manner, focusing on the design, management and implementation of a PCET.
