The principal aim of the OECD Environmental Performance Review (EPR) programme is to help Member and selected partner countries improve their individual and collective performance in environmental management by:
helping countries assess progress in achieving their environmental goals
promoting continuous policy dialogue and peer learning
stimulating greater accountability from governments towards each other and public opinion
This is the second EPR of Slovenia. It examines the country’s environmental performance since the previous review in 2012. Progress in achieving domestic objectives and international commitments provides the basis for assessing Slovenia’s environmental performance. Such objectives and commitments may be broad aims, qualitative goals or quantitative targets. A distinction is made between intentions, actions and results. Assessment of environmental performance is also placed within the context of Slovenia’s historical environmental record, present state of the environment, physical endowment in natural resources, economic conditions and demographic trends.
The OECD is grateful to the Ministry of the Environment, Climate and Energy for providing inputs on actions taken to implement select recommendations from the previous reviews, additional information and comments. We are also grateful to the Ministry for organising the review mission (17‑20 June 2025) and virtual policy mission (11 December 2025), as well as for facilitating contacts inside and outside government institutions. Thanks are also due to the representatives of the examining countries, Marek Engel (Slovak Republic) and Roald Wolters (the Netherlands), for participating in the review.
