Question

In Battle Environmental Evaluation System (BEES) of Environmental Impact Assessment (EIA), "air pollution'' has a Parameter Importance Unit (PIU) of 52. The Environmental Quality (EQ) score of a project with respect to air pollution was 0.8 before implementation and 0.6 after implementation. The difference in Environmental Impact Unit (EIU) is \(\underline{\hspace{1cm}}\). (round off to 2 decimal places)

Hint:

EIU directly scales with PIU. A small change in EQ results in a large change in EIU if PIU is large.

Answer 1

Correct Answer: 10.4

Environmental Impact Unit (EIU) is given by:
\[ EIU = EQ \times PIU \] Before implementation:
\[ EIU_{before} = 0.8 \times 52 = 41.6 \] After implementation:
\[ EIU_{after} = 0.6 \times 52 = 31.2 \] Difference in EIU:
\[ \Delta EIU = 41.6 - 31.2 = 10.4 \] \[ \boxed{10.40} \]
