Course Evaluation

• The Good
• This was an excellent course and I found it very
  interesting. It should help me further my
  employment when I get out of school
• Dr. Jansson is a great professor who teaches
  pertinent information about global issues. This
  course is a prime example of how Rowan
  differentiates itself from other learning
  environments
• Excellent job of stimulating critical thinking
  and discussion of the issues in class.
• I really enjoyed and learned a lot from this
  class. Prof. Jansson did a very good job making
  the material very understandable.
• It is a good class. The work load is set
  properly for the number of credits. I personally
  thought the energy part of this course was very
  interesting and very enjoyable.
• Great job!!! Prof. Jansson shows a level of
  enthusiasm rarely seen in the classroom.
• Prof. Jansson has taught me a lot about
  sustainability and environmental engineering.
  This course was a refreshing look at other ways
  to think of engineering.
• Prof. Jansson is really cool. Overall, very
  enthusiastic about subject and knowledgeable.
• Very enthusiastic and intelligent about the
  subject. Work load was excellent.
• Prof. Jansson has done a very good job at
  blending many aspects of Sustainable Design and
  presenting each of them in a very clear manner.
  As future engineers and designers, we now have
  the practical and analytical tools to contribute,
  in some way, to the field of sustainability.
• Prof. Jansson takes an interest in the students
  and their progress. He demands a high degree of
  commitment from students
• Very enthusiastic!

6
Course Evaluation

• The Bad
• The LCA portion needs some work to make it a
  little more interesting.
• The tests are too hard.He could attempt to
  involve students a little more in class - for
  example, group discussions, fun quizzes, etc.
• Often (I think) the assigned work was more
  perfunctory than thought-provoking. Give
  students more in-class group exercises, it helps
  particularly in this sort of subject
• The Ugly.
• Homework and tests were graded harshly.
• Assignments required intuitive thinking and were
  graded harshly.

25
Sustainable Development

• Although the idea is simple, the task is
  substantial. It means meeting four objectives at
  the same time, in the UK and the world as a
  whole
• social progress which recognises the needs of
  everyone
• effective protection of the environment
• prudent use of natural resources and
• maintenance of high and stable levels of economic
  growth and employment.

26
Quotable Quotes

• The pursuit of Sustainable Development is not an
  option - it is nothing more or less than a
  necessity for our economic survival Sir
  Iain Vallance - BT Chairman
• Sustainable Development is a widely accepted
  unifying concept for policymaking and the major
  new business challenge for the next century
  Dr. Colin Hicks - Director, Environment
  Directorate DTI
• The sustainability agenda is developing faster
  than any other part of the business agenda
  Livio Desimone - Chairman 3M
• We are about to go through a sustainability
  revolution which will rival the agricultural and
  industrial revolutions in its impact on society
  John Battle - DTI Minister of State

27
An Important Distinction

• Development
• application of resources human, physical,
  natural and financial to meet effective and
  prospective market and human needs. (improved
  quality not nec. quantity)
• Growth
• an increase in size or quantity by the accretion
  or assimilation of materials.

28
Key Issues of Sustainability

• Are There Limits to Growth? Resource Constraints
  vs. Substitution, Catastrophe vs. Expanding
  Horizons with Technology, Population Constraints,
  
• The Limits of Natural Capital
• Atmospheric CO2, Global Warming via Greenhouse
  Gases, Ozone Depletion
• Land Farming vs. Housing and Urbanization,
  Fertitility, Biodiversity
• Water Runoff, Pollution,
• Resource Limits Oil, Food, Minerals, Water

29
Some Important Concepts

• Exponential Growth
• Natural Capital
• Atmosphere
• The Oceans Hydrosphere
• Forests, Land Use, Resources Lithosphere
• Global Biosphere 3 Symbiotically Integrated
• Sustainable Levels/Rates

30
Doubling Times with Exponential Growth
31
Examples of Exponential Growth

• World Population
• World Industrial Production
• Atmospheric CO2 Concentration

32
Recent Growth Rates 1970-1990

• Global Human Population 2.0
• Number of Automobiles 4.1
• Use of Petroleum 1.7
• Coal Consumption 4.2
• Electric Generation Capacity 4.4
• Aluminum Used for Cans US 15.3
• Generation of Rubbish OECD 1.7

33
The Biosphere -Earths Natural Capital

• The integrated natural functioning atmosphere,
  lithosphere and hydrosphere working in cyclical
  patterns to sustain life on Earth. This includes
  the plant, animal and human species as well which
  all play a role at times in concert with and
  opposition to the apparently natural, sustainable
  cycles and rhythms.

34
Sustainable Levels/Rates for

• Renewable Resources (soil, water, forests, food,
  etc.) can be no greater than the rate of
  regeneration by the Biosphere
• Non-Renewable Resources can be no greater than
  the rate at which renewable resources can be
  substituted for them
• Pollutants no greater emission than the rate at
  which pollutant can be recycled, absorbed or
  rendered harmless by the Biosphere.

35
Current Great Debates

• Are there limits to growth?
• Have we solved the Ozone crisis?
• Is Oil running out any time soon?
• Is Global Warming really a problem?

36
Limits to Growth Debate

• THERE ARE LIMITS exponential growth is not
  sustainable when we must deal with a world of
  finite resources, therefore, policy-makers must
  intervene in the system and lead the way toward a
  sustainable future.
• LIMITS WILL BE REMOVED BY TECHNOLOGY any limits
  that exist will be removed as technology advances.

37
Ozone Problem Solved?

• YES Action taken to eliminate CFCs from
  manufacturing in Developed Nations should reduce
  trend of ozone depletion.
• MAYBE CFCs are only banned in some countries.
  Also, other gases high in the atmosphere,
  aircraft exhaust as well as supersonic transport
  will continue to disrupt the natural formation of
  O3 .

38
Ozone O3

• Absorbs harmful UV-B rays in stratosphere
• 10-50km layer above the Earth
• Very fine balance in its creation and destruction
  pattern O2 stripped via high radiation collides
  with available O2 -gt O3
• Very little in atmosphere

39
Quiz Show

• All the atmospheric Ozone if brought to sea level
  would have the volume of
• A) Rowan Auditorium
• B) A small refrigerator
• C) Cover of a book
• D) The head of a pin

40
Quotable Quote

• It is astonishing and terrifying to contemplate
  the narrow margin of safety on which our lives
  thus depend. Were this trifling quantity of
  atmospheric ozone removed we should all perish
• Dr. Charles Greeley Abbot of the SMITHSONIAN
  INSTITUTE quoted in NEW YORK TIMES - 30 October
  1933

41
Progress on Ozone Depletion

• While levels of Ozone depletion will continue to
  rise until 2010, it is believed that the ban on
  CFCs phased out by developed countries in 1996
  will have the effect of ultimately reducing CFC
  concentrations in the stratosphere. Hopefully,
  subsequent Ozone destruction after 2010 will
  significantly decline bringing the atmosphere
  back to pre-1980 Ozone levels by mid next century

42
Oil is Running Out Debate

• IT IS Our current supplies will last less than
  25 years at present growth rates and economic
  disruption is just around the corner (5yrs)
  unless we curtail use now
• IT IS NOT Our economically extractable reserves
  are over 1 trillion barrels and they will last
  over 40 years at present use levels, let the free
  market forces work.

43

• 1988-1998 220 BB
• Current Rate 25 BB/year
• Reserves 1-2.5 GB
• Growth in Use 2.0
• Depletion Years 20-40 years
• Peak Year 2000 - 2015

45
Oil and the Economy

• Supply vs. Demand
• 1970s US Experience of Arab Oil Embargo
• 1999-2000 Impact of OPECs 2.1M/day reduction in
  oil supply price tripled
• Restricted Investment Capital
• more to energy, more to food
• less for growth, jobs, expansion, etc.
• Increased Material Prices / Inflation

46
Global Warming Debate

• THE EARTH IS HEATING UP A broad spectrum of
  scientists have agreed that human activity is
  having a deleterious impact on global
  temperature.
• THE EARTH IS NOT HEATING UP All of the forces of
  nature make mans impact miniscule on the scale
  of things, we are observing normal fluctuations
  only.

47
Global Warming Is Real

• Man-made pollution rate increases 10 times
  between 1890 and 1970 levels
• CO2 levels are really rising in air
• Other Greenhouse Gases are rising in
  concentration also NOx,CH4, CFCs,
• H2O level in air will rise as well as temperature
  increases and compound the problem
• MUCH MORE NEXT WEEK
