Methods and Tools


Calculation tools

CO2 citizen calculator, waste calculator, building material assessment, municipal balancing tools - ifeu has developed these and other calculation tools in the context of scientific projects.


Instruments of quality control are more and more important for both public relations and the development and optimisation of policy programmes in the environmental sector. In consequence, ifeu has developed a strong focus on evaluation and accompanying social science research in recent years.


At ifeu, a range of state-of-the-art modelling tools are available for the quantification of technology and societal developments, environmental impacts, course of action, and impacts of policy or social interventions.

Sustainability assessment

In recent decades it is hard to think of any other term that has been so widely encountered and frequently misused as “sustainability” – or better still – “sustainable development”. ifeu has further developed the methods of sustainability assessment in many projects over recent years.

Life cycle assessment and material flow analyses

Life cycle assessments and material flow analyses are two of the most common methods used to map the potential environmental effects of products, processes, services and behaviour, and have been in use at ifeu since the end of the 1980s as key environmental assessment tools.

Risk analysis

ifeu conducts risk assessments, undertakes exposure analysis, and draws up environmental pathway models to evaluate chemical substances and radiation protection.


ifeu provides support with Environmental Impact Assessments (EIA) and Strategic Environmental Assessments (SEA) in the form of comprehensive studies, reviews and consultancy.

Life Cycle Impact Assessment

Ongoing work at ifeu continues to develop and update Life Cycle Impact Assessment methodology as part of Life Cycle Assessment. Our in-depth knowledge of indicators and models allows expert assessment of potential environmental impacts with appropriate methodology.
