Und noch eine kleine Veranstaltung mit Freund_innen aus dem Netzwerk #demokratische #Wirtschaftplanung moderiert von @ninatreu.bsky.social Vielleicht kommen wir dem näher, was ein demokratischer #Sozialismus auch bei @dielinkesachsen.bsky.social bedeuten könnte <3

Wir lesen eure Texte schon relativ genau und die Kritik zielt auch genau auf den Text. Die Behauptung "Material und Energie [sein] auch Arbeit, nur in verwandelter Form" ist schon gewagt und letztlich läuft es ja doch nur auf Arbeitszeit raus. Und wenn man das "Konsumniveau an die individuell ...

Ich halte eine ausschließliche Arbeitszeitbilanzierung auch für problematisch, insbesondere wenn es die Fortsetzung der Lohnarbeit ist und der Fetisch von Wert und Arbeit beibehalten wird. Eine Diskussion der Ansätze fände ich sehr sinnvoll, hier unser Vorschlag: www.youtube.com/watch?v=glZc...

One of the projects that has influenced me most over the past few years - the @futurehistories.bsky.social podcast by Jan Groos - is entering an exciting new chapter. Take a look and follow along to see what’s ahead. Or are you confident that we can make it without any structural change?

That makes LCSA more practical, more transparent, and more usable for decision support in real-world sustainability transitions. Maybe as a digital sustainability product passport for European Commission?

15 after Jeroen Guinée helped inspire the field with his 2011 "Life Cycle Assessment: Past, Present, and Future", HILCSA is the first robust and mature integrated LCSA method available. It goes beyond separate assessments of environmental, social, and economic aspects and brings them together.

Walther Zeug @waltherzeug.bsky.social · 31/03/2026
This makes HILCSA especially relevant for researchers, policymakers, industry, and civil society who need a way to compare products and technologies. For the field of #LCA and LCSA, this is an important step.

Walther Zeug @waltherzeug.bsky.social · 31/03/2026
HILCSA supports up to around 80 detailed indicators, which are aggregated into easy-to-understand indices and figures, and is implemented in openLCA with data sources such as soca and #ecoinvent.

In late-stage capitalism, many “new” technologies don’t change the system — they tend to sustain existing patterns of production and consumption, rather than transform them.

Compared to petrol cars, blend-fuelled ICEVs and BEVs show reduced aggregated environmental impacts (−6 % and −2 %). 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.

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.
