This document gives recommendations for implementing monitoring protocols, with a strong focus on participatory methods and tools. The document is part of Work Package 5 – “Monitoring and Documentation”, and it was developed in close collaboration with and for many project partners. The document language and length are meant to be understood by a wide range of people, with or without scientifi c knowledge in monitoring, as it is the intention that this document is an operational tool for anyone who aims to monitor ECS performance. The document is structured in four main sections: The first section sets out basic knowledge and questions that seem essential when considering to implement a monitoring protocol. What, how and when to consider a monitoring protocol is introduced, too. The following two sections, “Plan your monitoring” and “How to collect you own data” are meant to be used as look-up sections, with clear topics to consider, recommendations and examples of common methods used in monitoring protocols, in particular when considering participatory methods. The last section is an illustration of the implementation of such protocols in the Living Lab of the City of Oslo – one of the Front-Runner Cities in the project. This section should be read as an example of a possible application of the principles outlined in the document and is not necessarily representative of the real situation, as the selection of indicators and appropriate methods is still under development.
