Forest fires are gaining attention as a climate issue because they release greenhouse gases—mainly CO2—and because the forests that burn lose their ability to store carbon. In Hungary, the direct CO2 emissions from forest fires make up only about 0.29% of the country’s yearly emissions, but they still matter in the bigger climate picture. However, the long-term cumulative impact, the high emission rate per hectare and the resulting reduction in CO2 removal capacity are strategically important issues in achieving the 2050 climate neutrality goals. This research fills a research gap. It provides a quantitative analysis of forest fire emissions and removal losses using data from the European Forest Fire Information System (EFFIS) and national forestry statistics. The total CO2-related climate burden is projected to be approximately 4,300 kt by 2050. Despite modest absolute values, forest fires represent an under-recognized but growing risk in national climate planning. The results support the need for long-term policy integration of fire mitigation, afforestation and forest management strategies. This study provides a replicable methodology and practical knowledge for shaping climate policy in smaller EU Member States.
