A methodological framework for assessing regional climate efforts. Learning from its application in Italy

In multi-level governance systems, regions are key actors in tackling climate change, acting as a bridging authority between the state and municipalities. Regions can provide a common framework and support local action, in particular through ad-hoc or mainstreamed mitigation and adaptation strategies. Despite this, their contribution to multi-level climate planning is still little explored in the scientific literature. This work proposes a methodological framework developed to comprehensively assess the climate efforts of regional governments, based on three dimensions: ambition, robustness, implementation and progress. Ambition qualifies the regions' commitment. Robustness assesses the evidence-based approach of the plan and its link with the regional sustainable development strategy, as well as the regions’ involvement in transnational networks. Implementation and progress, records the availability of indicators to provide evidence of the actions taken, monitor progress, and inform stakeholders. Applying the proposed methodology to the Italian multi-regional case study sheds light on the weaknesses that limit the impact of climate action, while defining the factors that enhance climate performance. The results show that transnational networks can raise the level of ambition for mitigation, but less so for adaptation, where there are no quantitative targets or fixed target years. A science-based approach and a strong link to the regional sustainable development strategy provide a good degree of robustness, while tracking implementation and progress remains the most challenging factor. Good practices were also identified, based on the successful experiences of some Italian regions, which can be profitably transferred between regional authorities, but also to other sub-national governments. • A methodological framework for evaluating regional climate planning efforts. • No quantitative targets or time horizons characterise adaptation ambition. • Transnational networks can raise the level of ambition for mitigation. • Evidence-based approach and links to sustainability plans increase robustness. • Tracking implementation and progress is challenging, especially for adaptation.
