Abstract
Background: The European Commission (EC), based on the European Green Deal (2019) and the Recovery plan for Europe (2021) envisages investing 30% of the budget in climate-related programs, projects, and initiatives, which clearly shows Europe's commitment to becoming the first climate-neutral region by 2050. Activities are also planned for countries that are not members of the European Union (EU), which requires complex changes in the field of legislation, strategic planning, implementation, and monitoring. To successfully plan short-term and long-term activities on these grounds, it is necessary to have a realistic picture of the state of climate change in each country - as they spill over into the entire region of Europe. The main objective of this paper is to present the state of climate change in six Western Balkans countries, of which only Croatia is a member of the EU, for the needs of planning activities and initial harmonization with the EU plan to reaching net-zero greenhouse gas emissions (GHG) by 2050. Results: The main results of the research show that in all countries of the region, the average annual temperature increased by 1.2 °C compared to 1970, with stabilization and the beginning of the decline which can be expected around 2040. The main reasons for climate change in the region are: industry, energy, and heating sector based on coal exploitation, low energy efficiency, etc. Conclusions: It can be concluded that all countries of the Western Balkans have adopted (or are in the process of adopting) the necessary regulations and strategies towards climate change mitigation, but the implementation of specific activities is at a low level. The reasons for this most often lies in the insufficient commitment of decision-makers to make significant changes in the field of climate change transition (lower level of economic development, lack of investment, preservation of social peace). Finally, the paper provides an overview of climate change by country, scenario analysis, and policy recommendations.
