Engineer's Role in Mitigating Global Warming


The American Society of Civil Engineers has published a 73-page, a special issue of Leadership and Management in Engineering (July 2008) entitled Engineering Strategies for Global Climate Change. In this collection of feature articles, several writers present visions of the future for which the engineering profession needs to further respond and act.

Topics Include

  1. Power Generation: An array of 130 wind powerturbines located off the coast of Cape Cod, Massachusetts could provide up to 75% of that region’s electricity needs with zero carbon dioxide emissions, but the project is not without controversy. This project can be seen as a business case study of the trade-offs the United States must face for its energy future.
  2. Building Design: Designers of the next generation of buildings will aim for "zero energy" buildings in which there will be no need to draw energy from a region’s power grid. In this approach, climate and environment are used to advantage rather than being treated as adversaries and buildings become sources of energy, like batteries.
  3. State Climate Change Action Plans: These could mitigate the impacts of global warming andsave the economy billions of dollars, influencing how governments and agencies plan transportation projects in the future. In the absence of federal guidance, local action plans in the Western states are becoming increasingly prevalent.
  4. Storms, Flooding and Coastal Dikes: If reducing our carbon footprint is not enough, or such measures are of a scale that may not be effective or implemented in time, then we are compelled to consider the possible need for dikes, tidal, and wave protection structures for our coastal cities. This forward vision is discussed in "Must New York City Have Its Own Katrina?"
  5. Droughts and the Water Supply: The Southwest United States and other regions may run out of water as part of naturally occurring droughts potentially exacerbated by global climate change. The concept of a "water footprint" similar to that of the "carbon footprint" and the relationship between energy, carbon greenhouse gas emissions, and water is described.
  6. Land Use Implications: Alternative biofuels such as ethanol hold a prospect of reducing humanity’s carbon footprint, but the cycle of fuel delivery has important land-use, policyimplications. The jury may still be out on all the implications of these proposedgreenhouse mitigation policies and technologies, and the degrees to which they are likely to enhance our future.
  7. No-Regrets Technologies: A contrarian view is presented to what has now become the generally accepted consensus that the present global warming is largely caused by mankind’s activities. It acknowledges that global warming is occurring, but that it is a natural phenomenon, part of a 1,500-year cycle. Despite this, the writer advocates what he terms the use of "no-regrets" technologies.
