The article provides an overview of the Spanish legal system in terms of climate change legislation and the regulatory framework of the so-called energy transition. The configuration of the Spanish State as decentralised makes it necessary to allow the Autonomous Communities, as infra-state entities, to develop their own policy to fight climate change. The article thus explores the opportunity and advisability of adopting a multilevel model of relations between the State and the Autonomous Communities, in accordance with the European Union's climate neutrality requirements, and one that goes beyond the usual model of limited inter-administrative relations, based on the principle of coordination. First, the article deals with the basic State legislation on climate change and energy transition, with the aim of evidencing that the Autonomous Communities are necessary actors for the development and implementation of this framework. Second, it aims to provide an overview of what has been done so far by the Autonomous Communities. The article concludes with various reflections on the effectiveness of this decentralised model, insisting that its application is undeniable given that mitigation and adaptation actions have a territorial component that legitimises the intervention of infra-state entities.

The European Union climate policy and the subsequent energy transition are expected to cause fundamental changes in individual EU countries, their economies, and industrial sectors. Furthermore, in order to achieve them, high financial outlays are essential. The main purpose of the article is to present a comparative analysis of the pace, directions, and main factors of the energy transition in Poland and Spain against the changes in the EU energy and climate policy. In particular, the subject of the study is the changes in the fuel structure of electricity generation (energy mix) and the changes in the concentration of energy generation. The analysis concentrates on Poland and Spain against the background of the group of EU27 countries. The study adopted a long-term perspective (1990–2020). The methodology used taxonomic measures of variability of structures and measures of concentration, as well as measures of descriptive and mathematical statistics. The result of the research proves that the EU common climate and energy policy has explicitly accelerated changes in the energy mix, both in the EU27 and in the studied countries, including those traditionally based on coal. The concentration analysis demonstrated an increase in diversification resulting in a significant increase in the share of renewable and low-carbon sources. The taxonomic analysis additionally proved that there was a parallel process towards making the energy mix of the studied countries more similar to the EU27. The limitation of the research is the adopted triangulation arrangement of the studied structures (EU27, EU15, countries that accessed the EU after 2004), enforced in this pilot research, but possible to expand the field of perception in subsequent research. What serves as a proof of the originality of the study is the fulfilment of research gaps in the long-term study of the degree of changes in the concentration of the energy mix structure of EU countries, and especially the study of the degree of intensity of its similarity. The application value of the study is its use in the energy policies of countries traditionally based on coal for the indication of the taken position, the goals, and ways to achieve them based on the experience of other countries.

The aim of this article is to give an overview and systematic characterization of different national approaches to developing strategies of climate change adaptation from a spatial planning or regional development perspective, respectively. Based on this analysis, recommendations are made for the implementation of the Territorial Agenda of the European Union. The central research hypotheses addressed in this article are: (1) climate change impacts in Europe are distributed differently in European regions which influence the design of national adaptation strategies (NASs) in Europe as well as the planning-related fields of action; (2) the legal framework and the political-administrative system significantly determine how national adaptation responses are designed and by which institutions they are implemented and (3) spatial planning has the potential to play an important role in climate change adaptation due to its integrative, cross-sectoral character. In order to discuss the hypotheses, a meta-evaluation of already existing assessments of climate adaptation strategies was carried out, as well as nine in-depth country studies (Finland, France, Germany, Greece, Hungary, Poland, Spain, The Netherlands and the UK). The results show that spatial planning is only given minor attention in the assessed analyses and national strategies and that it is rather a matter of political willingness and capacity building than particular instruments or a high climate change vulnerability if spatial planning, however, plays an important role in an NAS.
