Fifa's report compared the emissions produced by the building of Stadium 974 to the average emissions of the four permanent stadiums that have a similar capacity of 40,000-45,000.
It found the temporary stadium "initially emits more carbon emissions due to the use of carbon-intensive materials such as metal and steel" - as opposed to mainly concrete in permanent stadiums - which allows it to be dismantled and reassembled multiple times.
So, as it stands, Stadium 974 has a higher carbon footprint than the comparable permanent stadiums built for Qatar 2022.
For the temporary stadium to have a lower total footprint than multiple permanent stadiums, Carbon Market Watch said it "depends on how many times, and how far, the stadium is transported and reassembled".
Fifa's study assessed three different scenarios for the future of Stadium 974, in which it is reused once, twice or three times in a series of differing locations.
It found if the temporary stadium is reused only once, it must be relocated "within a total sea and road travel distance of 7,033km" to be more "environmentally advantageous" than building two permanent stadiums. It also highlighted the environmental benefits of the stadium being repurposed within the region, or specifically in Qatar.
That maximum travel figure rises to 40,118 km overall for two reuses and 72,616km for three.
All three scenarios were also modelled on the temporary stadium spending four years in the first location and in each subsequent location, before operating the remainder of a 60-year lifespan at its final destination.
Where is the stadium going?
No decision appears to have been made on the future uses or locations of Stadium 974.
Carbon Market Watch said while organisers have "highlighted the dismountable nature of the temporary stadium, we could identify no specific plans showing where the stadium will be moved, if at all".
Uruguay is approximately 13,000km from Doha, so if the temporary stadium is moved there, it would have to be reused again in a third location in order to be more environmentally advantageous than building separate new stadiums in each place.
When asked about future plans for Stadium 974 and any possible locations, the organising committee said: "Qatar is on track to deliver the first carbon neutral Fifa World Cup.
"That means all infrastructure projects - including the eight stadiums - must meet stringent sustainability benchmarks.
"During their construction, we have recycled and reused wherever possible and implemented a vast range of energy and water efficiency solutions. In addition, materials from sustainable sources were used and innovative legacy plans have been implemented to ensure the tournament doesn't leave any 'white elephants'."
