Annex B: Monitoring and Evaluation
This section details the set of indicators we will use to monitor our progress towards the Transport Just Transition Plan outcomes.
These outcome indicators have been selected following a comprehensive review of a wide range of published data sources, experimental data, and bespoke research reports. Each indicator has been assessed for relevance, accuracy, availability, and timing. For some outcomes, there are gaps in data availability which make it challenging to identify a robust indicator at this time. In these instances, we are working on data development and any alternative sources of information that we will use to track progress on an interim basis.
We will collaborate with stakeholders across industry, academia and the public sector in the coming months to build on these published metrics and develop a comprehensive monitoring and evaluation framework. This will include working closely with the Just Transition Commission to ensure our approach is aligned with recently commissioned research on monitoring of a just transition in Scotland.
