Storyboard

3 basic types of indicators needed

why indicators, why sustainability?

what is my role as an engineer?

what personal development do I need?

thermodynamic realities

upstream design principles

redefine problem; look for human element

LCA & other tools

Sufficiency of human well-being for all

Sustainability of environmental integrity

Awareness of facts:Meadows/Daly framework for sustainable development indicators

Main point Sustainable development is a way of thinking that involves a) living within the thermodynamic limits of the natural system; b) Increasing the sufficiency of real human wealth for all.

Awareness of personal role:Mindset needed to engage in design for sustainable development

Awareness of strategies:Design strategies for sustainable development

Efficiency of creating well-being

Activity

What happens when expenses exceed income? Give examples of income, principle, and expenditures for economic, social and natural resources.

principle(economic, social

and natural resources)income

expenses ≤ income comfort, happiness, health

Using regenerated income, not principle

Increasing sufficiency of real human “well-being” for all

Engineer’s Creed

I dedicate my professional knowledge to the advancement and betterment of human welfare*. *welfare-health, happiness and fortune

Activity

Describe how preserving the environment is consistent with the “enhancement and betterment of human welfare” stated in the Engineer’s Creed. Alternative Activity

Draw a causal loop diagram that illustrates how preserving the environment is consistent with the “enhancement and betterment of human welfare” stated in the Engineer’s Creed.

Engineer’s Creed (National Society of Professional Engineers, 1954)

Sustainable Development

Sustainability Health Safety The joy of living

Activity

How do each of the four areas fit within the role of the engineer as expressed in the Engineer’s Creed?

Alternative Activity

Draw a causal loop diagram showing how the four areas fit within the role of the engineer as expressed in the Engineer’s Creed?

Classroom Activity

(2 minutes)

Discuss the above definition. What are needs of the present? What are needs of future generations? How those needs are met?

“Sustainable development meets the needs of the present without compromising the

ability of future generations to meet their own

needs”

(The World Commission on Environment and Development, United Nations,1987)

Our Earth: A Closed Thermodynamic System

Activity (2 minutes)

Identify the sources and sinks for materials used in our economy, which sits wholly within a closed, thermodynamic system? Do the same for energy.

Current human activity Michigan requires an equivalent of 8 x the actual area, or 4.6 M km2.

Is this sustainable?

Find five resources that are likely to run out first. How long are these resources expected to last? Do we need the products they support?

Materials Flows in the Economy

Interaction among Human and Environment

Evidence of past 30 years:

•the shrinking ice in the Arctic;

•melting glaciers;

•growth of cities like Las Vegasl

•forest loss in the Amazon;

•the decline of the Aral Sea and Lake Chad

Indicators

A Report to the Balaton Group, The Sustainability Institute, Hartland, VT (1998)

Sustainable Development

Indicators

like “design specifications”, they help you know when you have achieved your goal

Well-being

Natural capital

Social, human, and built capital to convert resources to well-being

From the Daly Triangle

19

Harmony, community, Enlightenment, self-respect

Knowledge, wealth, mobility

Labor, tools, infrastructure

Raw materials, solar energy, biosphere, biochemical cycles

Sustainable Development

Sustainable Development Indicators

real human well-being

environmental integrity

sufficiency for all

sustainability

measures ratio,or efficiency of converting resources to real human well-being2

Meadows suggests three indicator types:

Activity (2 minutes)

Pick any two of these three types of indicators. What would be the danger of only measuring these two?

Indicators = “design specifications”

Sustainable Development

Life Cycle Assessment (LCA)

o Inventories inputs and outputs of product or process life cycle;

o Converts inventory to impact in categories (e.g. global warming, acidification, aquatic toxicity, human health);

o Applies value-based weighting of categories to compute a single impact number.

Activity (5 minutes)

What is more valuable, to reduce atmospheric carbon dioxide emissions, to prevent aquatic toxicity, or to protect human health?
