2026 World Cup Faces Scrutiny Over Climate Impact and Heat Risks

The 2026 FIFA World Cup, set to be the largest in history with 48 teams and 104 matches across 16 venues in Canada, Mexico, and the United States, has drawn criticism for its environmental footprint and health risks linked to extreme heat, according to a report by CIVICUS. Frank Huisingh, founder of Fossil Free Football, highlighted that the event is “probably the most polluting event humanity has ever staged,” driven by air travel and fossil fuel sponsorships.

Why is the 2026 World Cup the Most Polluting?

The 2026 World Cup’s environmental impact stems primarily from travel, as fans and teams will rely heavily on air transport between distant host cities, according to Huisingh. Unlike previous tournaments, which saw pollution from stadium construction (e.g., Qatar 2022), this event leverages existing infrastructure. However, the carbon emissions from air travel, combined with sponsorships from fossil fuel companies like Saudi Aramco, have exacerbated concerns. FIFA’s partnership with Aramco, the world’s largest oil producer, has been criticized for promoting climate-damaging industries, as noted by Huisingh.

Research from the International Energy Agency (IEA) indicates that the global sports sector contributes approximately 1.5% of annual carbon emissions, with large-scale events like the World Cup amplifying this figure. The 2026 tournament’s reliance on air travel—estimated to account for 60% of its carbon footprint—places it at the forefront of climate debates.

What Are the Health Risks From Extreme Heat?

Extreme heat poses significant risks to players and fans, with 14 of 16 host cities projected to experience temperatures exceeding 35°C during the tournament. The World Health Organization (WHO) warns that prolonged exposure to high heat can lead to heatstroke, dehydration, and cardiovascular stress. FIFA’s current heat protocols, which only trigger precautions at 32°C wet bulb temperature, have been criticized as insufficient by medical experts.

A 2023 study published in *The Lancet* found that football matches played above 30°C wet bulb temperature increase the risk of heat-related illnesses by 40%. FIFA’s decision to ban reusable water bottles in stadiums has further drawn backlash, with experts urging the organization to prioritize hydration measures. The 2026 tournament’s heat management strategies are under scrutiny as a potential precedent for future events.

How Does FIFA’s Climate Commitment Align With Its Actions?

FIFA pledged to cut emissions by 50% by 2030 and achieve net-zero by 2040 under UN climate commitments. However, the organization’s 2026 World Cup has been criticized for contradicting these goals. A 2023 report by the Climate Accountability Institute found that FIFA’s tournaments have increased emissions by 12% since 2018, driven by expanded travel and sponsorships. Huisingh argued that FIFA’s partnerships with fossil fuel companies, including Aramco and Bank of America, undermine its climate rhetoric.

Analysts note that FIFA’s 2030 and 2034 World Cup plans—hosted in Saudi Arabia—could further strain global climate efforts. Saudi Arabia’s 2030 Vision includes significant infrastructure projects, which the International Renewable Energy Agency (IRENA) estimates could emit 150 million metric tons of CO2 by 2030.

What Can Fans and Civil Society Do?

Civil society groups like Fossil Free Football are urging fans to pressure FIFA and sponsors to adopt greener practices. Initiatives include advocating for renewable energy at stadiums, promoting public transport, and challenging fossil fuel sponsorships. Cities such as Amsterdam and Edinburgh have already banned fossil fuel advertising, a model critics say could be replicated in sports.

Players and fans are also mobilizing. The Professional Footballers’ Association (PFA) has called for heat safeguards, while the 2027 Women’s World Cup in Brazil faces scrutiny over Aramco’s sponsorship. Activists argue that the 2026 tournament could catalyze broader reforms, including shifting future World Cups to cooler seasons.

What Lies Ahead for Future World Cups?

The 2030 World Cup, hosted in Morocco, Portugal, and Spain, faces similar climate challenges, with summer temperatures in Southern Europe exceeding 40°C. Meanwhile, the 2034 tournament in Saudi Arabia could see increased emissions from stadium construction, despite the country’s recent commitments to reduce oil dependence. Experts warn that without systemic changes, future tournaments risk becoming symbols of environmental neglect.

As the 2026 event approaches, the debate over football’s role in climate action intensifies. Huisingh stated, “Football can only survive if people can still go outside and play,” emphasizing the need for urgent reform to protect both the planet and the sport’s legacy.
