本题解释:
正确答案： A
系统解析: The project building needs a 10% reduction in at least 3 of 6 impact categories - one of which must be GHG emissions. This means the reduction will need to occur in 2 of 5 categories, plus GHG emissions. No impact category can have an increase of more than 5% in order to ensure there is a net improvement in the environmental footprint of the design building versus the baseline building.
