The environmental impact of the 2026 World Cup is significant, with greenhouse gas emissions far exceeding previous tournaments. The health of players, officials, and fans is also at risk due to extreme heat, particularly in cities like Houston, Dallas, and Atlanta. The reliance on air-conditioned stadiums in some locations further contributes to energy consumption and emissions. Critics have labeled FIFA's sustainability efforts as 'greenwashing,' pointing to the lack of meaningful action to reduce the tournament's carbon footprint.
