World Cup stadiums earn LEED green building status but scientists warn of record carbon emissions from 2026 tournament

Thirteen of the 16 stadiums hosting the 2026 FIFA World Cup have achieved LEED certification, the global standard for green buildings. The upgrades save over 100 million gallons of potable water per year and eliminate more than five million single-use plastics annually. FIFA has committed to cutting emissions by 50% by 2030 and reaching net-zero by 2040. Using existing venues instead of building new ones also avoids construction-related carbon pollution. Despite these gains, scientists warn the 2026 World Cup will be the most polluting tournament ever. The expected nine million metric tons of carbon emissions from fan and team air travel across North America equals the annual output of nearly 6.5 million British cars. The article highlights the tension between venue-level sustainability gains and the massive travel footprint of an expanded 48-team tournament.
