NETHERLANDS / RankWire.AI / – According to an analysis conducted by Triodos Bank, Europe’s ongoing heatwaves and drought conditions could reduce the European Union’s economic output by approximately 1% in 2026. This estimated decline amounts to around €180 billion and coincides with a year already characterized by sluggish growth. The European Commission predicted in May that the EU’s gross domestic product would increase by 1.1% in 2026. This projection leaves minimal margin between the expected growth and the economic damage caused by this summer’s extreme weather events.
The primary driver behind the projected economic loss is a decrease in worker productivity during heatwaves, which the analysis estimates accounts for about 0.6% of EU GDP. Agriculture has also suffered considerably due to prolonged high temperatures and dry spells across key farming regions. The assessment suggests that agricultural output could decline between 3% and 7%. Additionally, disruptions in energy production, transport networks, and logistics further contribute to the overall economic impact, as elevated temperatures and reduced water levels interfere with normal operations.
During the summer, Western Europe experienced record-breaking temperatures. According to Copernicus, June and July combined marked the hottest period ever recorded in the region, with an average temperature of 21.62°C. This temperature was 2.79°C above the 1991-2020 average. July also saw widespread dryness across much of western and central Europe, with parts of France, Germany, Austria, Hungary, and the Iberian Peninsula experiencing their lowest soil moisture levels since at least 1979.
France’s GDP Faces the Largest Projected Decline
France is expected to bear the most significant national economic impact according to the bank’s estimates. The combination of heat and drought could cut French GDP growth by roughly 1.4 percentage points in 2026, translating to an approximate 0.6% contraction in annual output. Italy and Spain are also among the most vulnerable major economies, while Belgium is projected to experience a notable effect. The Netherlands might see a reduction of about 0.8 percentage points in growth, which could leave its economic activity nearly flat for the year.
This forecast of heat-related economic loss arises at a time when Europe is already experiencing a slowdown. The EU’s growth rate reached 1.5% in 2025, prior to the current deceleration projected for 2026. The Commission’s spring forecast predicted a 0.9% expansion for the euro area this year. Severe weather phenomena are exerting measurable pressure through lost working hours, decreased agricultural output, and infrastructure disruptions. When low river levels hamper transportation or high temperatures diminish electricity generation and industrial efficiency, these sector-wide effects tend to cascade across the economy.
Climate Extremes Increase Strain on Food Supplies and Manufacturing
Research has established links between extreme heat events and rising food prices, as well as declining corporate performance. The European Central Bank indicated that the 2025 summer heatwave contributed an increase of between 0.4 and 0.7 percentage points in euro area unprocessed food prices after one year. Separate studies at the company level in Italy have shown that extreme heat resulted in approximately 0.8% lower sales. Days with temperatures exceeding 40°C led to significant decreases in both production and productivity, according to these analyses.
The 2026 report emphasizes the immediate economic consequences of this summer’s heat and drought rather than longer-term climate projections. The projected 1% reduction in EU GDP closely aligns with the bloc’s 1.1% growth forecast for the year. The largest losses are attributed to decreases in labor productivity, with agriculture, energy, and transportation sectors adding further economic costs. Western Europe’s record heat and extensive soil moisture deficits underscore how severe weather phenomena have become a tangible factor shaping Europe’s economic outlook for 2026.
