Carbon Marker Watch said emissions from the eight World Cup stadiums had been under-estimated. It also questioned the way in which organisers said they would buy carbon credits to compensate for emissions that come from the tournament that runs from November 21 to December 18
A climate activist group on Tuesday cast "serious doubts" on claims by the Qatar World Cup organisers that this year's tournament would be carbon neutral.
"The event will have a large carbon footprint, and the findings of this report suggest that the 'carbon neutrality' claim is not credible," Carbon Market Watch said in a study that the World Cup organisers called "speculative and inaccurate".
CMW said emissions from the eight World Cup stadiums had been under-estimated. It also questioned the way in which organisers said they would buy carbon credits to compensate for emissions that come from the tournament that runs from November 21 to December 18.
Qatar, which has spent tens of billions of dollars on new stadiums and World Cup-related infrastructure, said last year the tournament would be "the first" carbon neutral World Cup.
