The U.S. Olympic team is one of a handful that will supply air conditioners for their athletes at the Paris Games in a move that undercuts organizers’ plans to cut carbon emissions.

U.S. Olympic and Paralympic CEO Sarah Hirshland said Friday that while the U.S. team appreciates efforts aimed at sustainability, the federation would be supplying AC units for what is typically the largest contingent of athletes at the Summer Games.

“As you can imagine, this is a period of time in which consistency and predictability is critical for Team USA’s performance,” Hirshland said. “In our conversations with athletes, this was a very high priority and something that the athletes felt was a critical component in their performance capability.”

The Washington Post reported earlier this month that Germany, Australia, Italy, Canada and Britain were among the other countries with plans to bring air conditioners to France.
