Programme for Brightcon 2023

Hackathon - Sept 16 & 17

On September 16 & 17, we will have a hackathon with the HESTIA team . HESTIA provides detailed and validated activity data on agriculture and food supply chains (currently the data are from more than 400 published studies and 35,000 farms). HESTIA also makes available nearly 500 models to gap fill farm activity data (e.g., to quantify ruminant grass consumption), to estimate agricultural emissions (e.g., N2O emissions related to fertiliser application), and to quantify resource uses. It is an open-source, open-access project and still in the development and testing stage, but is already the largest open dataset and model archive in this area. In the hackathon we will focus on integrating HESTIA with open LCA software, and simplifying the process of entering data into HESTIA.

Conference - Sept 18, 19 and 20

The conference will be a mix of talks, special sessions, and short courses. Being there in person is a lot of fun, but this year, with support from ecoinvent, we are also offering online attendance. Physical attendance is limited to 80 people, and we expect it to sell out, as it did last year.

The conference part of Brightcon 2023 will include (changes are still possible):
  • Premise hands on
  • Open data
  • Feedback on the Brightcon 2022 visualization contest
  • News from the Brightway development roadmap
  • What's new in the Brightway documentation project
  • Contribution analysis with Brightway and other modules
  • Full SQL database backend solution for Brightway
  • Overview of progress/plans for the AB

Instructors for Brightcon 2023


Researcher at the Technology Assessment Group of the Paul Scherrer Institute

Romain Sacchi is a researcher at the Technology Assessment Group of the Paul Scherrer Institute since June 2019. He contributes within the field of LCA applied to future mobility technologies. More specifically, Romain investigates the opportunities and challenges related to the electrification of mobility, considering all the environmentally-relevant phases along the life cycle of transportation services. More recently, he developed a keen interest in energy system models and Integrated Assessment Models and their application to LCA.


Professor at Aalborg University


PhD in Life-Cycle Assessment for Sustainable Aviation

Michael Weinold is a doctoral researcher in the Group for Technology Assessment at Paul Scherrer Institute and the Department of Mechanical and Process Engineering of ETH Zürich. His research interests include life-cycle assessment for sustainable aviation and methodological improvements for hybrizing life-cycle inventory. His research is undertaken as part of the WISER Innosuisse flagship, an interdisciplinary project funded by Swiss Innovation Agency. It is aimed at providing a web of interoperable digital services for knowledge on decarbonisation pathways.

Sander van Nielen

Sander van Nielen obtained his MSc in Industrial Ecology in Leiden in 2016. Afterwards, he worked at the municipal engineering department in Rotterdam for two years. Now he is back at CML, doing PhD research on the recycling of rare earth magnets. His research focusses on the development of ex-ante LCA methods and the resilience of supply chains. By combining insights from industry partners with sophisticated computational methods, more insight in the environmental aspects of magnet recycling will be created.
