3. LIFE CYCLE ASSESSMENT
 “Life Cycle” - Major activities of a product’s life-span
from its manufacture, use, maintenance, to its final
disposal.
 “LCA” – Systematic evaluation to Identify , Measure ,
Characterize different potential environmental impacts
associated to each one of the stages of the life cycle of a
product.
 Identify environmentally critical points and prevent or
remove them using other materials or systems.
 Follows international rules (ISO 14040 standards).
 Quantitative and qualitative assessment.

7. NEED OF LCA
 Product / project - Development / improvement
 Strategic planning
 Public policy making
 Marketing and eco-declarations
 Improving environmental footprint
 Identify waste reduction
 Capitalize on regulatory changes
 Improve product/corporate image
 Develop metrics and enable comparison across the company
and among suppliers and partners
 Secure market and competitive positions
 Answer customer’s requests for environmental and social
information
 Identify cost savings

9. LIMITATIONS
 Inaccurate or limited data
 Comparison of products - differing system
boundaries, differing uses, different
statistical information
 Limited guidance – location specific
 Resources and time specific
 Uncertainties over implementation of results
 Lack of awareness
 Validity
