Carbon emissions, match-day temperatures, and fan attendance across every World Cup — from 1930 Uruguay to 2026 USA/Canada/Mexico. Track how the planet has warmed alongside the world's biggest sporting event.
The average temperature in host cities during World Cup match days, from 1930 to 2022. The rise since the 1970s is unmistakable — a direct consequence of global warming that is now shaping how and where the tournament can be held.
The temperature anomaly shows how much warmer (or cooler) each World Cup was compared to the 1951–1980 baseline for that host city. The trend line confirms a sustained upward trajectory driven by global climate change.
How much did each host country's national CO₂ emissions change between the year they won the bid and the year they held the tournament? This measures the "hosting cycle effect" — infrastructure, construction, and energy demand driven by preparation.
Total fan attendance per tournament. Higher attendance means more travel — a major driver of tournament carbon footprint. The 2026 expansion to 48 teams and 104 matches is projected to attract over 5 million fans.
