• To get accreditation
• To stake claims – Green label, Eco-mark• To market and promote product
• To get Tax and other fiscal benefits
• To improve export of the products
• To improve product design
• To improve products environmental quality
• To improve production process
• To improve energy efficiency
• To find appropriate alternate rawmaterials

EIA How it is done
Steps
Select a product
Collect base line data
Quantitative inventory of raw materials used
Quantitative inventory of production process steps used Identify environmental issues associated with each material & process
List Environmental issues that are needed to be resolved
Prepare priority list for environmental remediation
Look for alternative raw materials that are environmentally safe
Quantify the environmental costs/indicators/indexes
Normalize the above
Compare the normalized values with benchmarks/standards or
competitors identical product
Draw conclusions

EIA Environmental Remediation
Reduce burden on Environment: 3.
Take care of post life remnant of the product:
Take back the used up material and recycle or dispose in the safest
manner
Compensatory measures:
Tree plantation (carbon sequestering)
Recycle waste materials totally
Use renewable energy
