Introduction to Engineering and Environment

I have uploaded the questions (ass 1).

Paper is due to the 19th

1. Question 1.5 ( Rubin’s Book) :

How do concepts of green design, industrial ecology, and

sustainable development differ from past approaches to

engineering design? Prepare a brief report on this topic, using some

specific examples for illustration.

2- Using the Canadian National Pollutant Release Inventory

(through the Environment Canada Website), choose any 3

chemicals and determine their quantities released to the air,

water and land.

3- 3.Question 2.11(Robin’s book)

Investigate the estimated resource base of world energy supplies of either crude

oil or natural gas (choose one), one useful website is the Energy Information

Administration of the U.S. Department of Energy on (www.eia.doe.gov).

Comment on when or whether we might be “running out” of this non-

renewable recourse based on current estimates. Also discuss whether the

environmental implications of future energy resource extraction might change

because of the location or difficulty of exploiting the remaining reserves.

Summarize your findings in a brief report.

4-4.Question 12.15 (Robin’s book)

Use the 20-year Global Warming Potential (GWP) values in Table 12.9 to

calculate an equivalent CO2, emission rate for worldwide greenhouse gas

emissions as given in Table 12.1. Assume that total CFCs are divided equally

among the three compounds listed. What is the percentage contribution of

actual CO2 emissions to the total equivalent C02? What is the next most

important greenhouse gas emission based on this analysis? How do these

results compare to those using the 100-year GWP in Example 12.17?
