Our new paper on holistic sustainability of community supported agriculture is available! It is really impressing what community supported production and consumption systems can contribute to sustainability already today.

Yet, both come with burden shifts toward the social and economic dimensions: total impacts rise by 8 % for the blend-fuelled ICEV and by 30 % for the BEV.

Our new paper applying the HILCSA method to passenger cars highlights an important point: alternative drivetrains are not automatically more sustainable.

Paludiculture offers a promising land-use pathway to cut GHG, restore biodiversity, and support sustainable development. Using the HILCSA method, socio-ecological interactions could be better understood. However, reliable primary I/O data is still too scarce to conduct LCAs.

Thrilled to have joined the 1st Int. Conference on Absolute Sustainability – “From Less Bad to Good Enough” at DTU! In my talk and this article, I explored some systemic implications that Absolute Sustainability Assessments have but are often neglected: systemic transformations.

🌍 In a time of accelerating ecological overshoot and inequality, we need bold, systems-level approaches. This work brings together ideas from cybernetics, democratic planning, and sustainability science to explore how we might govern economies in service of both people and planet.

🚀 Just had the honor of presenting at the openLCA Conference 2025!
🎤 My talk, “Exploring New Frontiers in Absolute Sustainability: Cybernetic Democratic Economic Planning”, introduced a novel framework to monitor and plan the satisfaction of societal needs within planetary and regional boundaries.
The recording is now online:

Für das Landesamt für Umweltschutz Sachsen-Anhalt (LAU) haben wir mit HILCSA drei Fallbeispiele (Baustoffe, chemische Industrie und Nahrungsmittel) gerechnet und analysiert: Nicht alles, was biobasiert ist, ist auch nachhaltig. Es braucht eine ganzheitliche Perspektive!

On December 18th 2024, Solveig Degen and me held a presentation on "#Banks in the #DemocraticEconomicPlanning Debate" at the Workshop "Banks and #PostGrowth" from Center for Sustainable Economic and Corporate Policy (ZNWU). Thanks Janina Urban for inviting us!
The new German bioeconomy monitoring report was published! We contributed results from stakeholder participation, which will soon be published. Unfortunately, the current development of bioeconomy is going in the wrong direction from the perspective of our stakeholders.

It was a pleasure to be there! Stay tuned for our future activites and publications in this regard.
