What is Sustainability?


    AMEC’s Definition
           Sustainability is an
           approach to
           managing our
           earths resources
           and environment for
           the best interests of
           all those affected by
           what we do both
           now and in the
           future.

Principles of Sustainability

    Basic Principles
       – minimizing the use of
         non-renewable
         resources
       – minimizing impacts on
         the natural environment
       – protecting biodiversity
       – using renewable
         resources in a
         sustainable manner

Sustainable Development

    Development that meets the need of the
     present without compromising the ability of
     future generations to meet their own needs.

Ultimate Sustainable Roads
Green House Gas Eating Pavements


     Pavements in Westminster, London may soon have a role that
     goes far beyond creating smooth roadways. Japan's Mitsubishi
     Materials Corporation has developed a paving stone called
     "Noxer" that uses the catalytic properties of TiO2 to remove
     nitrogen oxide (NOx) from the air, breaking it down into
     environmentally benign substances that are washed away by
     rainwater. NOx is produced in abundance through vehicle
     emissions.

Tools for Measuring Sustainability
European Technology



    The Waste & Resources Action Program

    The tool focuses on giving an estimate of the CO2 saved in selecting
     different construction techniques and supply alternatives (use of
     primary or recycled and secondary aggregates).
    The tool uses Microsoft Excel and is designed to assess the CO2
     output resulting from four types of construction involving aggregates:

       – • bitumen bound
       – • cement bound
       – • water bound
       – • unbound

Sustainability – Should We Worry?

    A few Comments from England:
       – Because of the potential environmental impacts of major
         construction projects, alternatives to new road construction
         will be thoroughly investigated first. (Recycling)
       – New roads are expensive. They impose substantial
         environmental costs. Can problems can be solved by
         making better use of the existing network before adding
         additional infrastructure? (Environmental Issues)
       – Road-building must be accompanied by measures to lock
         in the benefits, i.e. prevent new traffic from filling up the
         new road space. (Restricted Traffic Use)

China’s Reaction to Transportation
Sustainability

    By 2004 their rail network was the 3rd largest in the
     world, the road system the fourth largest, the expressways
     ranked second. Rate of growth was not controlled or
     sustainable.

    Recognising the seriousness of this situation the China
     Council for International Cooperation on Environment and
     Development (CCICED) decided, in November 2003, to
     establish a Sustainable Transportation Task Force

    The Sustainable Transportation Task Force was charged
     with implementing a project entitled "strategy and policy
     for the development of sustainable transportation in China

What is Changing? Why this
emphasis now?

    Growing awareness of
     problems or issues
    Increasing intolerance with
     use of “free goods or
     services”
    Mistrust of global
     organizations
    Information age has
     increased power of third
     parties.
    Expectation that something
     be done

These Are The Facts!

    Oil prices are approaching $100/barrel.
    Hydrocarbon Emissions are ever increasing.
    Environment activists with Power Point
     presentations are winning the Nobel Prize.
    None renewable resources are decreasing.
    Our world is warming up.
    Canada is committed to a path of environmental
     sustainability.
    Are we doing our share in the transportation
     sector?
