3. INTRODUCTION
The shortage of raw materials ,climate change,
growing variety of customer –challenges.
automotive industry lightweight design
predominant innovation.
modern engineering need environmental
advantages across the whole product lifecycle
(PLC).

4. SUSTAINABILITY
Meeting the need of current and future generations through
integrating environmental protection, social advancement and
economic prosperity.
Field of sustainable engineering is management activities of
sustainable consumption of nature.
4 ways to be sustainable
Reduce usage of fossil fuels
Reduce use of synthetic substance
Reduce encroachment of nature
Meet human need effectively and fairly

11. STRATEGIES OF LMOD
 lightweight design requires an integrated view of product design,
material selection and production process .
 weight-optimized material selection process inside the regular product
development process.
minimizing negative environmental impacts within the product lifecycle
resulting from optimized materials use.
Economic growth

12. EXTERNAL ASPECTS AND
IMPACTS
Triangle of project management
Environmental aspects
3 fundamental strategies
Sufficiency
Efficiency
Consistency
Major levers
Design
Material
manufacture

13. The extraction of raw materials, the
manufacturing and processing, the
distribution and use as well as the end-
of-life phase, including the final recycling
or degradation process.
