3. What is the difference between primary, secondary, and tertiary data sources?
4. How are scoping, stakeholders and the Life Cycle Impact Assessment related?
Using the Carnegie Mellon EIO-LCA website (http://www.eiolca.net/Method/LCA_Primer.html), determine the life cycle impacts of The Papadopoulos family holiday gifts. Mrs. Papadopoulos received a new coat worth $100. Mr.Papadopoulos received two tickets to see his favorite hockey team play for $150. Their children received and XBox 1 and accessories worth $500.
a.) The Papadopoulos family lives in the United States and the year was 2013. Which EIO-LCA model should you use and why?
b.) To analyze the impact of the purchases, what EIO-LCA sectors should you use for each member of the household's gifts?
c.) The prices above are in 2013 dollars. Use the Bureau of Labor Statistics Inflation Calculator to estimate the 2002 prices for each of their gifts.
