It's so depressing to see all this brand new housing in apartment buildings in car-centric streets.

I think that a building with the best temperature energy efficiency but within a bad urban form (to which the building itself is contributing), shouldn't get a good energy certification.

🔝 Are you ready to shape the future of environmental and social research?

🤩We're offering six fully-funded PhD positions in the framework of the María de Maeztu Unit of Excellence.

hahah that is true. The document I was reading is anything but anarchist as well.

Like this local knowledge should be one step of policy and also of some science. But now many policies and strategies are tested/modelled/explored by scientists and we should be giving some fundamental idea of what could be discussed in local policymaking and what is not possible, right?

I'm not going to know how to express this well but I don't like policy advice that focuses more on ideas like 'local knowledge' and 'co-production' and not specific solutions.

Yo no entiendo de cronobiología pero en el Mediterráneo solo hay temperatura agradable (fresquito) muy temprano por la mañana en verano, y es justo donde más raro quedaría el horario de invierno de amanecer en verano. Ahora mismo es lo único que me preocupa de todo este tinglado y no se habla

Hi ha una idea que és la base de molts debats actuals (inclosos el canvi climàtic, l'educació o el català): per fer aprendre o actuar hem de ser seductors o hem de ser exigents?

Transparency in turbine composition is still a challenge due to the opacity of industry, but WindTrace offers a flexible, open approach to have informed estimates to bills of materials and life cycle impacts.

We compared WindTrace to Ecoinvent, ran sensitivity analyses, and explored how different design choices affect climate change impacts per MW and kWh.

In this new paper, we present WindTrace: a parametric Life Cycle Inventory model for onshore wind turbines built in Brightway, led by Miquel Sierra Montoya (@icta-uab.bsky.social). It estimates bills of materials and environmental impacts based on turbine and farm parameters.

Turbine composition is largely intransparent and existing Life Cycle Inventory datasets rely on outdated wind turbine models such as the 4.5MW cement tower in Ecoinvent, which don't reflect currently evolving and growing turbines and can overestimate environmental impacts.

Someone on Twitter replies to me: "meh. buy american or stfu." 

Two hours later, in a separate thread, the write: "$30 for a single button-up is ridiculous unless it is decent quality silk."

This two-parter below is exactly why it's hard to make clothes in the United States.

Let's look at how much it costs to produce a button-up shirt in the US. 🧵

Raul Velasco: The invisibilized burden: care work and its unequal global exchange"
YouTube video by ICTA-UAB Raul Velasco: The invisibilized burden: care work and its unequal global exchange"

Missed Raúl Velasco’s webinar last Tuesday?

You can now watch it in full on YouTube! 🎥

In this REAL project talk, he explores how the Global North’s growth relies on massive amounts of unpaid care work—mostly by women—appropriated through unequal exchange.

(clarification: I've known about this since I started working with value added, but this sounds like accounting engineering to ensure GDP growth)

Imputed rent - Wikipedia

As a person who has previously worked with machines and production processes, value added is still a mistery (despite 8 years in ecological economics academia) and this imputed rent for home owners accounting for value added still sounds very weird to me. en.wikipedia.org/wiki/Imputed...

Sobre esto, acabo de quedarme boquiabierto con este cambio, que intuía pero que no creía de tal magnitud ni tan rápido. Viene del último informe del Observatorio de la Transición Justa (www.observatorio-transicionjusta.com/informe-2025...)

I'm thinking that there should be a number of pages for a single reviewer's comments that should be either considered as "reject" or as a co-author.

Isn't it a bit weird when we know some people are working separately on the same topic and research becomes kind of a race?

De fet dos ciclistes s'han hagut de parar i anar caminant pel costat, li han recriminat i el senyor del cotxe els ha respost de males maneres

Em sembla fascinant la mentalitat de superioritat de qui utilitza el cotxe d'aturar-se pràcticament bloquejant el carril bici quan tens dos carrils pels cotxes i no en passen gaires.
