FIFA faced significant challenges in managing sustainability and player safety during this year’s World Cup held across the United States amid some of the most extreme heat conditions experienced in tournament history. Federico Addiechi, FIFA’s head of sustainability, outlined the complexities involved in staging the quadrennial event under soaring temperatures, which raised new concerns about climate change’s impact on global sporting events.

The World Cup, like the Olympics, often draws criticism for its environmental footprint, given the substantial carbon emissions associated with international travel, fossil fuel sponsorships, and extensive venue construction required to accommodate the tournament. This year’s edition in the US was no exception, but the addition of extreme heat presented unique challenges that necessitated new measures for player health and event management.

To mitigate the risks associated with high temperatures, FIFA adjusted the scheduling of matches to avoid the hottest parts of the day. Venues that lacked roofs were equipped with enhanced cooling systems and air conditioning to maintain safer conditions for athletes and spectators alike. Additionally, the tournament introduced mandatory water breaks during each half of the game—an unprecedented move aimed at preventing heat-related illnesses among players.

These measures follow similar concerns raised during the 2022 World Cup in Qatar, which was rescheduled to the autumn months to avoid the region’s intense summer heat. The 2026 tournament underscored how climate change is increasingly influencing the planning and logistical aspects of international sports competitions.

FIFA’s efforts to address sustainability amid these challenges reflect a broader recognition of environmental issues within the world of sports. While the organisation continues to face scrutiny over the environmental effects of its events, officials emphasize their commitment to adapting and improving practices to safeguard both players and the planet as climate risks intensify.
