Life cycle assessment (LCA)
LCA is a powerful tool for assessing the environmental performance of products, services or scenarios
It is based on material and energy flows for processes and materials that together form a life cycle

Life cycle assessment (LCA)
We use world-leading software and databases and apply ISO standards
- ISO 14040 Principles and framework- ISO 14041 Goal and Scope Definition - ISO 14042 Inventory Analysis- ISO 14043 Interpretation - ISO 14025 Type III environmental declarations

Inventory
What data do we need to satisfy the goal and scope?
Who do we need to contact for information?
With what level of information are we satisfied?
Incoming and outgoing material and energy flows for every process and material

Impact Assessment
How do we translate 1 kWh of electricity to an environmental profile consisting of different environmental impact categories?
By using equivalency factors for different substances and adding them up to a total:
From carbon dioxide and methane to global warming
1 kg carbon dioxide = 1 kg GWP-equivalents1 kg methane = 24 kg GWP-equivalents------------------------------------------------------------------
Total = 25 kg GWP-equivalents

Impact categories
A range of impact categories can be distinguished• global warming• depletion of non-renewables• depletion of the ozone layer• acidification• eutrophication• summersmog• aquatic ecotoxicity• terrrestrial ecotoxicity• human toxicity• energy• non-hazardous waste• hazardous waste• …

Our experience
We have an extensive experience gathered over a period of more than a decade in applying LCA to over 300 materials and many scenario studies
We build sector specific tools and databases
We assist producers in innovation and product improvements
We train people and organizations in life cycle thinking
What can we do for you?
