Hjem | Økonomiskolen 2025 Økonomiskolen er et progressivt kursusforløb, der præsenterer dig for emner og perspektiver på økonomi, som ikke prioriteres på danske økonomiuddannelser, og som sjældent indgår i den offentlige debat...

Det er i morgen, der er deadline på at ansøge til okonomiskolen.dk

Kom og vær med når vi sammen med en masse dygtige forskere konfronterer de store spørgsmål om verdens kriser og disses uretfærdighed.

Darum ist es so schwer, weniger Plastik zu produzieren Die Welt verhandelt weiter über ein Plastikabkommen. Warum ist es so schwer, die Plastikproduktion zu senken?

Why is it that capping the production of plastics is so contested?

Got to provide some input to this great piece by @katharinamau.bsky.social

Plast er olieindustriens redningskrans Bliver den punkteret i Genéve? Skal vi blive fossile brændsler kvit, så er det ikke nok at udfase olie, gas og kul som energiform. Danmark sidder med for bordenden ved de vigtige forhandlinger, der skal lukke plasthanen.

Klimamonitor sætter i dag sat ord på vigtigheden af en global plastiktraktat for klimadagsordenen.

Giver selv lidt perspektiv fra min ph.d.: »Kemiindustrien er fuldkommen sammenfiltret med olie-, gas- og kulindustrien. Dermed er deres skæbner også forbundne.«

Interesting developments... The contradiction on which the initiative is founded could not be contained.

The city of Beit Hanoun in the north east edge of Gaza is seen from above. It is completely destroyed, not a single building is standing. It is all rubble, as though the aftermath of a nuclear explosion. The city had a population of 52,000

Gaza is now single deadliest conflict for journalists in history.

This is not only an attempt to extinguish a whole people, it is also an attempt to extinguish the story of their genocide.

On a global scale, the claimed overcapacity does not lead to oil demand for petrochemicals peaking – the IEA expects demand for oil for petrochemicals to continuously increase throughout the decade.

Oil 2025 – Analysis - IEA Oil 2025 - Analysis and key findings. A report by the International Energy Agency.

The IEA has published its yearly report on the state of oil—a key publication when following trends in petrochemicals and oil as a material.

It confirms the increasing importance of synthetics in energy transitions: "Demand growth [is] underpinned almost exclusively by petrochemical[s]."

Ethvert folkedrab retfærdiggøres på samme måde: netop denne befolkningsgruppe er unik farlig og kan ikke behandles efter normale regler. Armenerne var forræderiske, tutsierne magtsyge, jøderne konspiratoriske. Nu er det så palæstinensere, der alle er terrorister eller ikke elsker deres børn.

Detoxification alongside defossilisation changes how we should think of and approach climate change

A/HRC/59/42: The imperative of defossilizing our economies - Report of the Special Rapporteur on the promotion and protection of human rights in the context of climate change The present report clarifies States’ international human rights obligations and businesses’ responsibilities to phase out fossil fuels and related subsidies within the current decade. The interlinked,...

Just learnt that the Special Rapporteur on the promotion and protection of human rights in the context of climate change is now also calling for a climate agenda beyond decarbonisation, including both defossilisation and detoxification.

🔹Humanitarian aid and supplies have not entered the #Gaza Strip for over 50 days now. Critical humanitarian supplies are rapidly depleting. UNRWA flour supplies have run out.

Notatet er tilgængeligt her.

Hovedresultatet er, at vi bør styre efter kraftige reduktioner frem mod 2035.

Hvad skal målene for de danske forbrugsbaserede udledninger være?

Klimarådet siger det. Klimabevægelsen siger det. Selv Dansk Industri siger det. Vi skal have pejlemærker for drivhusgasudledninger relateret til forbrug.

Men hvad skal de være? Det har vi i Klima- og Omstillingsrådet nogle bud på.

Thanks a lot, Rob!

Synthetic transitions: the political economy of fossil fuel as feedstock With simultaneous policy and scholarly attention to the pollution crisis and the climate crisis, there is growing recognition that the two are intimately interconnected through the demand for oil, ...

Transforming a Synthetic World: The Political Economy of Petrochemical Transitions

This paper builds on my PhD thesis and is an effort to unpack the most important conceptual and strategic implications that arise from understanding the role of fossil-based feedstock in production and consumption systems. portal.research.lu.se/en/publicati...

9/10

The dilemmas and limitations of defossilization strengthen the need to move beyond "plug and play" approaches to energy transitions, which focus on substitutability and shifts in technology and energy sources but not on ownership, control, modes of provision, or power relations.

8/x

1️⃣ Defossilization reveals a petrochemical complex that stretches across key sectors of the economy, from energy and agriculture to transport, health, and the military.

2️⃣ The current petrochemical complex enforces limited or "synthetic transitions," which are neither sustainable nor just.

7/x

We discuss the dilemmas and put forward a set of conceptual and strategic implications of appreciating fossil fuels as feedstock.

6/x

We know decarbonization, but what about defossilization? To decarbonize, we need to defossilize. But defossilization also risks entrenching existing inequities and perpetuating environmental and climate injustices.

5/x

However, that might very well be a fallacy. Research suggests that we need to defossilize—we need to do away with fossil carbon to begin with and base industrial production on renewables. Otherwise, lock-in ensures that fossil extraction continues at massively problematic scales.

4/x

Around 16% of the oil extracted globally ends up as synthetic materials. With electrification of transportation, this number is set to increase. In fact, in a net-zero world, the International Energy Agency expects that the share of oil for "non-energy purposes" will exceed 50% in 2050.

3/x

To get to a world without fossil fuels essentially requires an energy revolution. Fossil hydrocarbons are used not only for energy purposes but also to produce petrochemicals, used for all synthetic materials, be they plastics, textiles, or rubber. Even carbon fiber for wind turbine blades.

2/x

Together with @peternewell.bsky.social, I have a new paper out in RIPE.

In this paper, we explore why and how the use of fossil hydrocarbons for non-energy purposes (as raw material for synthetics) changes how we should approach the climate crisis.

In the final section of the paper, we discuss limitations, assumptions, lessons for practitioners and more, providing a schema for absolute environmental sustainability assessment informed by sufficiency-thinking.

Link to paper: eur02.safelinks.protection.outlook.com?url=https%3A...

We use the results to inform a sector-level sharing principle prioritising material and energy for fulfilling human needs.

For impact categories where additional ecological space below the boundaries exists, we allocate that space across activities by degree of luxury.

From this model, we find that for some impact categories, we do not stay within planetary boundaries.

For climate impacts, this is partly because the variables for the planetary boundary for climate change are already above their boundary level (419 vs. 350 ppm and +2.79 vs. +1 W/m²).

To make such a prioritisation, @jonaskromand.bsky.social developed an LCA model designed to meet decent living standards for all people in Denmark in 2050. A huge undertaking whose main goal was to define the environmental impacts of meeting human needs (find all details in the paper).

The question we ask is: How much ecological space can a given activity rightfully claim as a share of Earth's carrying capacity?

Many approaches exist, but we argue that we should start from a premise of sufficiency—prioritising goods and services that enable the satisfaction of human needs.
