NETHERLANDS / RankWire.AI / – According to a report by Triodos Bank, extreme heat and drought conditions across Europe could slash about 1% from the European Union’s economic output in 2026. This estimated loss, roughly €180 billion, occurs amid a year already characterized by sluggish growth. The European Commission forecast from May projected EU gross domestic product to grow by 1.1% in 2026. This baseline suggests little margin between the anticipated economic expansion and the potential damage from this summer’s severe weather patterns.
The primary factor behind the projected decline is reduced worker productivity during extreme heat episodes, accounting for approximately 0.6% of EU GDP. Additionally, agriculture faces notable stress due to prolonged periods of heat and drought in key farming regions. The assessment estimates agricultural output could drop between 3% and 7%. Disruptions in energy production, transport networks, and logistics further contribute to the overall economic impact as high temperatures and diminished water levels interfere with normal operations.
This summer, Western Europe experienced record-breaking temperatures. According to Copernicus, June and July combined marked the warmest such period ever recorded in the region, with an average temperature of 21.62°C—2.79°C above the 1991-2020 average. July also brought widespread dry conditions across much of western and central Europe. Several areas, including parts of France, Germany, Austria, Hungary, and the Iberian Peninsula, reported their lowest soil moisture levels for July since at least 1979.
France experiences the greatest potential GDP decline
France faces the most significant impact among EU countries in the bank’s projections. The combination of heat and drought could cause a reduction of about 1.4 percentage points in French GDP growth for 2026. This translates to a nearly 0.6% contraction in annual economic output. Italy and Spain are also among the more vulnerable large economies, while Belgium is expected to see a notable effect. The Netherlands could experience a growth dip of roughly 0.8 percentage points, bringing its economic activity close to stagnation for the year.
This assessment comes amid already slowing economic growth in Europe. EU expansion slowed to 1.5% in 2025, with a further projected slowdown in 2026. The Commission’s spring outlook forecasted a 0.9% increase in the euro area this year. Severe weather events exert additional pressure through lost working hours, diminished agricultural yields, and disruptions to infrastructure. These effects often ripple across sectors, especially when low river levels hinder transportation or high temperatures impair electricity generation and industrial productivity.
Extreme climate events intensify food and manufacturing challenges
Research indicates a link between extreme heat and rising food prices along with declining corporate performance. The European Central Bank found that the 2025 summer heatwave contributed an additional 0.4 to 0.7 percentage points to euro area unprocessed food prices after one year. Separate studies at the firm level in Italy revealed that extreme heat reduced company sales by approximately 0.8%. Days exceeding 40°C also caused notable losses in production and efficiency, according to these findings.
The 2026 analysis emphasizes the immediate economic consequences of this summer’s heat and drought rather than long-term climate projections. Its estimated 1% reduction in EU GDP is close to the 1.1% growth forecast for the year. The largest portion of these losses stems from decreased labor productivity, with agriculture, energy, and transportation sectors also contributing. As Western Europe experiences unprecedented heat and widespread soil moisture deficits, these figures underscore how extreme weather has become a tangible factor influencing Europe’s economic outlook in 2026.
