The impact assessment for a new sports stadium states that the stadium will contribute to climate change because it will emit around 1,800 kg of carbon dioxide per square meter. The builders’ priority is to make it as environmentally friendly as possible while still meeting the community’s needs. Which of the following recommendations is most likely to appear in the life-cycle interpretation?
The stadium should not be built because it contributes to climate change.
The stadium should be built because the city’s existing stadium emits slightly more carbon dioxide per square meter.
The city should pass legal limits on the amount of carbon dioxide emissions allowed.
The builders should cut carbon emissions by using concrete instead of steel in some areas.
