A Pathway Towards Sustainability

How the engineering profession can contribute to the movement towards sustainability

by

William A. Wallace

Sr. Vice President

CH2M HILL

presented to the

Engineers International Roundtable

National Academy of Engineering

13 September 2002

moving toward a sustainable future
Moving Toward a Sustainable Future
  • How do you shift from a non-sustainable pathway toward a sustainable pathway?
  • Problems
    • Legacy investment in non-sustainable technologies, processes and systems
    • Sustainable development viewed as an expense, not as an opportunity
    • Poor environment for innovation
three steps
Three Steps
  • Develop a practical awareness of the sustainable development issue
  • Create a sustainable project roadmap
  • Develop a sustainability knowledge base
developing a practical awareness of the sustainable development issue

Developing a Practical Awareness of the Sustainable Development Issue

Is sustainable development an issue worthy of concern? What are the metrics of sustainability

conditions for sustainability
Conditions for Sustainability
  • Renewable resources (ecological)
    • Use < Regeneration
  • Non-renewable resources (minerals, fuels)
    • Use < Development of renewable substitutes
  • Pollution emissions
    • Emissions < Carrying capacity of environment
the debate over sustainability
The Debate Over Sustainability

ResourceConstrained

ResourceAbundance

Ecological Resources (Renewable)

No real resource shortages

Little ecological damage

Substantial ecological damage

Impending resource shortages

Reaching carrying capacity

Carrying capacity not in jeopardy

Minerals, Metals, Fuels Resources (Non-Renewable)

No real resource shortages

Technology not capable of making additional needed resources economically available

Impending Resource Shortages

Technological advances will continue to “save the day”

creating a sustainable project roadmap

Creating A Sustainable Project Roadmap

If sustainability is an important issue, then how will we change course? Making progress project by project.

approach
Approach
  • Create a sustainability framework for evaluation
  • Advance the state-of-the-practice
    • Determine current state of the practice
    • Set targets based on best-in-class technologies, achievements by others
    • Evaluate using sustainability-based criteria
    • Systems evaluation
  • Sustainability is a journey, not a binary choice
  • Economic viability is critical!
five step process
Five-Step Process
  • Step 1: Project Vision
    • Where are you going
  • Step 2: Fatal flaw analysis
    • What issues might cause the project to fail?
  • Step 3: Benchmarking
    • What existing projects can be used as indicators and benchmarks for sustainable development?
  • Step 4: Sustainable technologies
    • Which technologies can be incorporated into the design that meet SD principles?
  • Step 5: Systems integration
    • Do systems meet target benchmarks?

developing a sustainability knowledge base

Developing a Sustainability Knowledge Base

Develop and maintain a knowledge base of sustainable projects and technologies

developing a sustainability knowledge base13
Developing a Sustainability Knowledge Base
  • Scan the world of technologies
    • Evaluate technologies against sustainability criteria
    • Use a sustainability framework (TNS, other)
  • Scan the world of projects
    • Learn and record what has been achieved
    • Verify performance
  • Maintain and disseminate the information
technology evaluation

Challenge

Training of engineers:

  • who have the skills and tools appropriate to address the issues that our planet is facing today and is likely to face within the next 20 years
  • who are aware of the needs of the developing world
  • who can contribute to the relief of the endemic problems of poverty afflicting developing communities worldwide

”ESE is a multidisciplinary (engineering, science, social science, and governance) process of solution development that takes a holistic view of natural and human system interactions. The goal of ESE is to better understand complex, nonlinear systems of global importance and to develop the tools necessary to implement that understanding”

(National Academy of Engineering, 2000)
