Europe's burned area is heading for +39% to +192%, and suppression spending is the swing factor

A study led by the Potsdam Institute for Climate Impact Research (PIK), with contributions from the Senckenberg Society for Nature Research, projects that the area burned each year in Europe rises by roughly 39% under a low-emissions pathway (SSP1-2.6) and by about 192% under a high-emissions one (SSP3-7.0) by the end of the century ^[1][2][3]. The same paper finds that continued improvement in prevention, early detection and firefighting could cut projected burned area by 92% in a 1.8C world and 72% at roughly 3.6C, which moves suppression capacity from a public-safety topic to a capital-planning variable with a modelled return ^[8].

The numbers are comparisons of the projected 2070-2100 annual average against a modelled 2000-2030 reference period ^[4]. The two scenarios correspond to warming of about 1.8C and about 3.6C respectively, according to lead author Maik Billing ^[5]. Billing says increases in burned area are widespread even at the lower figure, and that at 3.6C fires become much more prevalent around the Mediterranean and across much of Western and Central Europe, including areas that have not seen many fires to date ^[6][7]. That last clause is the land-use point: the exposed set is not the historically exposed set, so siting rules, vegetation management and access planning written against a fire history are calibrated to the wrong baseline.

The distance between the two scenarios is roughly five times in percentage terms ^[14], but the distance between managed and unmanaged outcomes within a single scenario is larger. That is the part operators control. Co-author Thomas Hickler of Senckenberg frames it as an investment question covering trained crews, proper equipment and coordination, while warning that containment may break down above some fire intensity and that the location of that threshold is not known ^[10]. He points to the recent record fires in France as evidence that past experience is not a safe basis for extrapolation ^[10]. The authors also flag that their own fire-management results may be optimistic about how well suppression works in a much warmer climate ^[9]. A 92% reduction is a modelled ceiling under continued improvement, not a promised delivery.

Current-season data gives the near-term scale. The European Forest Fire Information System recorded around 550,000 hectares, or 1.36 million acres, burned across the EU as of 12 August 2026, about two and a half times the 20-year average for that point in the year ^[11]. That implies a 20-year benchmark of roughly 220,000 hectares by mid-August ^[15]. Co-author Kirsten Thonicke says the fires in France, Spain and Greece show how quickly hot, dry, windy weather stretches firefighters and their resources, and that conditions could become extreme enough to hit hard limits on prevention and suppression once fires pass a certain size ^[12]. The paper's stated position is that emissions cuts remain essential and that prevention, detection and suppression have a key role alongside them ^[13].

Worth noting what is not in the results: they are expressed in burned area, not in losses, claims or budget lines ^[2][3]. Anyone converting these percentages into reserving or procurement assumptions is adding a step the paper does not supply.

What to watch: whether the unknown containment threshold Hickler describes gets bounded by later work ^[10], whether EFFIS end-of-season totals keep running multiples above the 20-year average ^[11], and whether newly exposed regions in Western and Central Europe budget for capacity before their first bad year rather than after it ^[7].
