Sustainability, appears to be something that is desirable, but the engineer (student or practicing) is left ignorant as to what it specifically implies for them.

3. SUSTAINABILITY AND
SUSTAINABLE ENGINEERING
• Misconceptions about sustainability and
sustainable engineering
– Green engineering
– Renewable energy
– eco-design, disassembly/recycling and
designing
– stop polluting, reduce emissions, prevent
waste

4. What does ‘sustainability’
mean?
• The Brundtland definition:
Development that meets the needs and
aspirations of the present without
compromising the ability to meet those of the
future is sustainable development

5. Few points observed from
Brundtland definition of
sustainable engineering:
• Not only concerned about environment
• No mention of technology
• Engineers- there is again no explicit
mention of them
• no mention of the commercial spectrum

6. Sustainability and Development
• Sustainability implies at minimum
• Development is not mere survival

7. AN ECOSYSTEM APPROACH
FOR SUSTAINABILITY:
sustainable development
means development of the
whole ecosystem including
humans, biota, environment,
and all.

9. Sustainability and the stool
• Triple Bottom Line
Three pillars of sustainability – economy,
environment and society

10. Sustainable engineering
• Sustainable engineering can be defined as
‘ensuring the sustainability of the entire
commercial spectrum, from product to
planet, across the Triple Bottom Line of
socio-, enviro- and econo-sustainability’.

11. Product examples:
The millennium development goals (MDGs) by UN:
The goals are:
1) Eradicate extreme poverty and hunger
2) Achieve universal primary education
3) Promote gender equality and empower women
4) Reduce child mortality
5) Improve maternal health
6) Combat HIV/aids, malaria, and other diseases
7) Ensure environmental sustainability
8) Develop a global partnership forTemplates

13. Key principles that underpin
sustainable engineering :
• KP 1: While the varied understandings of sustainable engineering
are all valid in themselves, a full understanding requires all three
aspects of the Triple Bottom Line.
• KP 2: Designing for the environment is not designing for
sustainability.
• KP 3: Product line longevity is a requirement, and can lead to
econo- and socio-sustainability.
• KP 4: A product must satisfy its key functions if it is to be econo-
sustainable.
• KP 5: The quality of sustainable products must be at least as good
as that of the equivalent non-sustainable product, if not better.
• KP 6: Econo-sustainability, and thence all sustainability, relies on a
true understanding of the consumers wishes and demands and the
consequent product functionality required

14. Conclusions of Sustainability
and Sustainable Engineering
• Key principles can help practising engineers and
engineering students, who are usually not specialists in
sustainability,to find the place of sustainable engineering
within their own disciplines and professional lives
• Triple Bottom Line of socio-, econo- and enviro-
sustainability.
• Equally, it must be remembered that econo-sustainability
is only the starting point that socio- and enviro-
sustainability can build on.
