For ecological footprint of manpower, refer Sect. 0 in methodology.
The ecological footprint of DWB box is calculated on the basis of raw materials
required and their individual ecological footprints (Table 8)
b. Sample Calculation of Industrial Sustainability Index (ISI)
ISI is calculated based on Eq. 1
ISI =
RVA ∗ EMP
CO 2 emissions
RVA = 4.912Million Rupees/year . . . (data from industry for FY 2018−19)
EMP = 13
CO 2 emissions = Energy Consumed through various sources ∗ Emission factor
CO 2 emissions = 55, 150 kWh ∗ 0.001186 tCO 2 /kWh = 65.4tCO 2
ISI =
4.02782 Million Rupees ∗ 13 persons
65.4tCO 2
ISI = 0.80 units
The environmental and economic analysis of the industry is done for the existing
technology and suggested modes. The effects of the earlier discussed modes in
Sect. 1.2 are explained as follows:
c. Mode 1 (Replacement of grid-based electricity with grid-connected solar
PV electricity)
