Triple bottom line: • Three dimensions or pillars of sustainability• Optimization of Financial capital, Social capital and Natural capital
• Trade‐offs between the dimensions?• Can the three dimensions be traded off freely?

Circular economy• eco‐design• increased efficiency of manufacturing
• reduced use of chemicals (accumulate through loops)
• product‐service systems, sharing economy
• use of recycled materials and resources
• industrial symbiosis
Products must be planned and engineered in a life cycle perspective

Life Cycle Engineering (LCE)Life cycle engineering (LCE) has a central role to play, but what is it?
• a systematic “cradle to grave” approach that “provides the most complete environmental profile of goods and services”1
• Focus on design and manufacture of products, optimizing the product life cycle and minimizing pollution and waste2 while at the same time encouraging economic progress
• LCE tools are life cycle‐oriented: • Analysis tools like LCA and LCC• Synthesis tools under the heading of Life cycle design
• … or life cycle stage‐oriented:• Green Material Selection, Design for Disassembly (DfD), Design for Recycling (DfR), energy efficient manufacturing, …

Life Cycle Engineering (LCE) framework – why and how?
Why?• Position engineering activities relative to other efforts to achieve a sustainable development
• Guide LCE practitioners towards creating engineering solutions that are sustainable in absolute terms
How?• Organize engineering activities throughout the life cycle of a product or a technology
• Position them according to their leverage in terms of promoting sustainable production systems and a sustainable society
• … considering the dimensions of scale and time • … introducing absolute boundaries for sustainability

The sustainability challenge
• I is the environmental impact
• Pop is the global population
• is the Affluence, the material standard of living
• is the Technology factor – environmental impact per created value

The sustainability challenge
• The global population may level off around 10 billion•Material standard of living will grow strongly in newly industrialised countries (Asia, South America)
• The environmental impact already exceeds sustainable levels in many areas
• So what is the challenge?

The technology factor
must decrease 4‐20 times in order to• counterbalance the expected growth in population and material consumption
• achieve the needed reduction in the environmental impact

LCE in absolute terms
LCE is thus redefined as • sustainability‐oriented product development activities within the scope of one to several product life cycles
• aiming to achieve sustainable manufacturing that allows fulfilling needs of both present and future generations without exceeding the boundaries of Earth’s life support systems

Outlook
Sustainability pushed into national and corporate agendas by UN’s World goals for 2030 and quest for circular economy Emphasis on importance of life cycle engineering
Focus of LCE must shift from triple‐bottom line thinking towards• environmental sustainability dimension (Earth’s life support function)• absolute sustainbility targets rather than relative improvements• developing tools that target eco‐effectiveness rather than eco‐efficiency improvements
• operationalizing large scale sustainability targets at the level of companies
The presented LCE framework aims to support this development
