In Belgium alone, more than 1,200 excess deaths linked to high heat were recorded during the June 2026 heatwave.

• The ~1,200 figure was a provisional estimate announced by the Belgian Health Ministry in early July 2026 (about 1,200 deaths, later specified as 1,222, between 18 and 29 June); the consolidated toll was subsequently revised upward to a minimum of 1,747 excess deaths (some later reports cite around 2,000).
• The metric is all-cause excess mortality above the seasonal baseline during the heatwave period, conventionally attributed to the heat, rather than deaths certified as directly caused by heat.
• The primary source consulted (health.belgium.be) may have been published on or just after the session date, but the data it reports (18-29 June 2026) and the Ministry's announcement (2 July 2026, per Reuters) predate the session of 8 July 2026, so the MEP could have known the figure.
