While football fans focus on the performances of teams such as Curaçao, the environmental impact of the 2026 FIFA World Cup may go largely unnoticed. According to Greenly, the tournament could generate a record 7.8 million tonnes of CO₂-equivalent emissions—roughly comparable to the annual emissions of Sierra Leone. Nearly 88% of this footprint is expected to come from spectator travel, highlighting the climate implications of the expanded tournament format with 48 teams, 104 matches, and 16 host cities spread across three countries.
The tournament presents a climate paradox. On one hand, unlike previous World Cups, it required no new stadium construction, avoiding a major source of emissions. FIFA has emphasized sustainability measures, including public transport promotion, waste management, reduced use of diesel generators, and long-term infrastructure benefits for host cities. The organization also aims to cut emissions by 50% by 2030 and achieve net-zero emissions by 2040. On the other hand, the tournament’s vast geography shifts most emissions to areas that are harder for organizers to control, particularly the travel of millions of fans, media representatives, and other participants.
The debate extends beyond the total volume of emissions to questions of transparency and accountability. Following criticism of FIFA’s carbon-neutrality claims for the 2022 World Cup, sustainability reporting standards are becoming more rigorous. Updated frameworks, including ISO 20121 and the new GRI climate standards effective from 2027, require more detailed disclosure of Scope 3 emissions, calculation methodologies, and the use of carbon credits. For major sporting events, this means greater scrutiny of emissions from travel, accommodation, broadcasting, logistics, and other indirect sources before claims of carbon neutrality can be credibly made.
