Of the seven stadiums Qatar built for the World Cup, one will disappear after the tournament.

That’s what the games’ organizers have said about Stadium 974 in Doha — a port-side structure with more than 40,000 seats partially built from recycled shipping containers and steel.

Qatar says the stadium will be fully dismantled after the World Cup and could be shipped to countries that need the infrastructure. Outside experts have praised the design, but say more needs to be known about what happens to the stadium after the event.

Buildings are responsible for nearly 40% of the world’s energy-related carbon emissions. Of that, about 10% comes from “embodied” carbon or the greenhouse gas emissions related to the construction, maintenance and demolition of buildings.

Qatar has faced international criticism for its treatment of low-paid migrant workers who built over $200 billion worth of stadiums, metro lines and other infrastructure for the World Cup. Qatar says the criticism ignores labor reforms enacted in recent years.

Stadium 974, named after Qatar’s international dialing code and the number of containers used to build the stadium, is the only venue that Qatar constructed for the World Cup that isn’t air-conditioned. During a match Friday in which Switzerland defeated Serbia, the air was noticeably more humid and hot than in other venues.

The stadium is hosting only evening matches, when temperatures are cooler.

Fenwick Iribarren Architects, which designed Stadium 974 and two other World Cup stadiums, says the idea was to avoid building a “white elephant,” a stadium that is left unused or underused after the tournament ends, as happened following previous World Cups in South Africa, Brazil and Russia.

Qatar says it has developed plans for the other six stadiums after the games are over. Many will have a number of seats removed.
