Which option identifies what Steven should use during the process in the following scenario and correctly explains why? Steven is conducting a life-cycle inventory of all of the energy and raw materials used in every stage of the production of an eco-friendly home. It is important that this is done correctly since the impact analysis evaluates the effects of the product on the environment, and also on human health, based upon the product’s energy and raw material input and output.
Exact numbers should be used so that calculations can be as precise as possible.
Exact numbers should be used, but calculations can be rounded to the nearest estimate.
Estimated numbers should be used so that calculations can be as variable as possible.
