Key facts
- Europe's extreme summer heat is projected to erase the EU's entire economic growth for 2026, costing €180 billion.
- France is expected to experience economic contraction.
- Over 14,000 people died during a late June heat wave.
- Drought conditions are severely impacting agriculture, transport, and energy production.
- Rebuilding costs from wildfires are expected to be in the billions.
Europe's scorching summer is projected to erase the European Union's entire economic growth for 2026, costing an estimated €180 billion, with France facing economic contraction. The continent is grappling with severe consequences of extreme heat, including widespread wildfires, devastating droughts, and record-low river levels.
Experts emphasize that global warming, rather than climate policy, is the primary driver of these economic damages. The summer has seen over 14,000 deaths during a late June heat wave and forced nearly half a million people to flee wildfires. The costs of rebuilding from fires in Spain and France alone are expected to run into the billions.
Lost productivity due to high temperatures is significantly impacting businesses, with workers' output declining and energy costs rising due to increased demand for air conditioning. Insurance group Allianz estimates cumulative GDP losses of up to 7 percent between 2026 and 2030 across several major European economies.
Drought conditions are wreaking havoc on agriculture, with the June heat wave wiping out an estimated 9 million tons of European grain crops, resulting in a €2 billion revenue loss for farmers. Critical transport arteries like the Rhine River have reached record-low levels, forcing barges to reduce loads and disrupting supply chains, potentially impacting Germany's GDP.
Energy supply is also under strain. Low water levels in the Danube River are threatening nuclear power stations in Hungary and Romania, leading to reduced output and potential shortages. Serbia's hydropower is strained, and its oil refinery faces potential closure due to shipping disruptions. France has also shut down nuclear reactors due to drought and low river levels.
The economic toll of wildfires is substantial, with previous studies estimating annual losses of up to €2.1 billion for Southern European countries. France estimates the cost to restore burnt forest land at €10,000 per hectare.
