The recent heatwave in June cost Germany's economy at least €6.3 billion in losses due to falling productivity, signalling the direct and immediate impact of climate change on the country's financial system.
Context and impact on the forestry and agricultural sectors
Heat stress in Germany is beginning to reach levels typical of the Mediterranean region, seriously threatening tax revenues and placing additional strain on the healthcare and social systems. Although the report's main focus is on manufacturing, construction and services, agriculture and forestry are among the most vulnerable sectors
Extreme heat (above +40°C) directly affects animal welfare in food production, causing productivity losses and livestock mortality. At the same time, heatwaves in late June coincide with grain ripening and the start of harvest, intensifying drought, reducing crop yields and hampering fieldwork during the hottest hours of the day.
Prolonged, intense heat significantly raises the risk of forest fires and accelerates the spread of wood pests (such as bark beetles), which have been ravaging Germany's forests for years already. In such conditions, forestry workers face severe heat stress that brings planned work in the forest to a halt.
The June heatwave has cost Germany more than six billion euros
The unprecedented heatwave that hit Germany and much of Western and Central Europe in late June 2026 cost the German economy at least €6.3 billion through lost productivity, the newspaper Handelsblatt reports. In an analysis commissioned by the newspaper, the consultancy Prognos examined the drop in worker productivity during the hot period as the main driver of the economic losses. Companies surveyed said they had faced higher costs linked to increased demand for cooling, changes to working hours and protective measures.
The biggest impact on productivity was found in the manufacturing sector, where estimated losses reach €1.9 billion, followed by healthcare, social services and retail. Heat also significantly affected construction and the energy sector. High temperatures were particularly critical for workers in hot working environments, such as factories and construction sites, as well as for farm animals. The authors stressed that the estimated losses reflect only a lower bound, since higher energy prices, equipment damage and supply-chain disruptions were not included.
Late June brought temperatures above +40°C to many European regions, with several countries recording new temperature records. Manfred Fischedick, head of the climate think tank the Wuppertal Institute, told Handelsblatt that the economic threats posed by climate change should be taken just as seriously as, for example, competition from China: “These debates need to be linked.” Handelsblatt notes that experts estimate three to four similar heatwaves are possible in Germany each year, meaning annual productivity losses from heat stress could exceed €20 billion.
The insurer Allianz had already forecast in May a productivity drop of three percent for every additional degree above +30°C, while demand for cooling rises by 1.2% per degree. This, in turn, means higher costs for the state through lost tax revenue and additional spending on healthcare, infrastructure and social protection in response to high temperatures.
The Prognos analysis shows that on days when the temperature exceeds +35°C, economic losses can reach almost one billion euros a day. Earlier in the week, Germany's national weather service, the DWD, said the June heatwave was a “turning point” in Germany's adaptation to climate change, since the country must now prepare for the kind of heat stress that, until now, had been typical only of Mediterranean countries in Europe.
Long-term economic forecasts for Europe through 2030
Forecasts from leading insurers and international economic think tanks show that recurring, intense heatwaves will turn into a massive macroeconomic shock for the whole European Union by 2030. The downtime and productivity losses caused by climate change are no longer just a theoretical risk but a real factor that will significantly reduce European countries' gross domestic product (GDP) and distort financial markets within the next few years.
A possible collapse in national GDP and investment
The economic losses will hit the largest economies of Southern and Central Europe hardest. Calculations by the insurance giant Allianz Trade show that, by 2030, the direct impact of heatwaves in France, Italy and Spain could cause GDP to fall by 5–7% compared with a baseline scenario in which no climate crisis occurred. In monetary terms, that translates into losses of roughly $240 billion for France, $147 billion for Italy and $120 billion for Spain. Even Germany, Europe's economic engine, which sits in a more temperate climate zone, will face a GDP decline of up to 3% by the end of the decade, equivalent to losses of around €112 billion.
The most significant threat lies in the fact that heat undermines not so much short-term consumption as companies' willingness and ability to invest in future growth. Experts estimate that corporate investment in France could fall by 14.7% due to heat, and by 12.8% in Italy. Returns on capital decline for businesses because vast sums have to be redirected into solving everyday problems, such as cooling premises, maintaining infrastructure and protecting workers, rather than into innovation or expanding production.
Food price inflation and the risk of stagflation
The European Central Bank (ECB) stresses in its reports that global warming and increasingly frequent droughts will directly affect consumer prices. It is forecast that, by 2030 already, heatwaves in Europe will push up food price inflation by 0.4–0.9 percentage points. This effect could even double in the coming decades. Falling agricultural yields and rising logistics costs (for example, rivers drying up and paralysing freight transport) create serious risks of stagflation – a situation in which economic growth stalls or slows while the cost of living and prices keep rising sharply.
Fiscal pressure on national budgets
Every degree above the +30°C threshold reduces workers' productivity by roughly 3%. For governments, that means a double hit to the budget. On one hand, tax revenue shrinks, because companies produce less and workers earn less (in Germany, tax revenue is forecast to fall by 0.7% a year). On the other, government spending will rise sharply, since the heat will require funding additional healthcare services for those who fall ill, adapting critical infrastructure such as railway tracks and power grids, and providing social support programmes for sectors hit by heat-related downtime. Year by year, Europe will feel itself getting more “scorched”, both literally and figuratively.
