CIRP LCE 2018, LCA Short Course

Addressing the most critical issues in LCA: from theory to practice

Below is the detailed programme of the course. A downloadable version is available here.

Date and time: 29 April 2018, 08:30 – 17:00

Course length: Full day (08:30 – 17:00). Lunch is covered by the course registration fees.

Location: Tivoli Hotel & Congress Center*, Room Dansetten

*Please note that the entrance to the Tivoli Hotel Congress Center is right next to the main entrance to the Tivoli Hotel. Tivoli Hotel Conference Center is just across the street from the conference venue of IDA (Association of Danish Engineers Conference center).

Conference registration: the course participants can do their registration for the entire conference from 08:30 – 09:00 in Room Arkaden 6 of Tivoli Hotel & Congress Center before the LCA course starts.

Course objective: The objective of this course is to give guidance on how to address the most critical issues that an average LCA practitioner is faced with when carrying out and documenting an LCA study. Completing the course will allow participants for an educated and more confident modelling and reporting of LCA studies in the future.


Course level: The course is designed for those who are already familiar with LCA to some extent and have carried out or participated in carrying out an LCA before.

Instructors: Senior researcher Mikolaj Owsianiak & Associate professor Alexis Laurent, Division for Quantitative Sustainability Assessment, Dept. of Management Engineering Technical University of Denmark

About the course instructors

Mikolaj Owsianiak, Senior Researcher, PhD in Life Cycle Impact Assessment

LCA practitioner. Coordinator of LCA activities within several European research, demonstration and innovation projects.  He has also worked closely with small and medium size enterprises (SME) applying LCA to assess sustainability of technologies developed by the SMEs. Involved in an EU FP7 project LC-IMPACT on development of life cycle impact assessment methods for dealing with terrestrial toxicity of metal emissions. He is a contributor to methodology chapters providing a comprehensive and pedagogic introduction to LCA methodology, and first author of an illustrative case study providing an example of how to structure a report according to the ISO requirements (for details, see new LCA textbook Hauschild et al. 2018, Life Cycle Assessment. Theory and Practice).

Alexis Laurent, Associate Professor, PhD in Life Cycle Assessment

LCA lecturer, practitioner and developer. He has run the course on life cycle assessment given at DTU since 2014 (Master level, 80-120 students, 10 ECTS), in which students perform real-life full-fledged LCA case studies in collaboration with companies and institutions (for details, see Cosme et al. 2018, Learning‐by-doing: experience from 20 years of teaching LCA to future engineers). He has worked in the field of LCA for the past 8 years, with research focus on life cycle impact assessment (LCIA) method development (incl. normalisation), footprinting of large-scale systems (sectors, countries), and applications of LCA to systems in various domains, including waste management, nanomaterials and energy sectors.
