Our project looked at climate neutrality 🇩🇪 2045.
Buildings built in '25 have an operational greenhouse gas emission budget of 6.86 kg CO2e/(m²*a) + embodied 6.41 kg CO2e/(m²*a).
By 2045, these budgets will be reduced to 1.05 and 0.79 kg CO2e/(m²*a), respectively.

Cool, but why should homes be built out of bricks in the first place.

I hate to break it to you, but most modern insulation (the pink stuff you see in new construction) is actually made from glass. Primarily recycled glass bottles and the like. It's also non-flammable, unlike straw. Why try to find issues where none exist? Spend your energy somewhere where it matters.

Complete peatland restoration is an absolute no brainer. It's such a low hanging fruit, that it's a litmus test if your government is serious about climate goals, biodiversity etc.
"Drained peatlands in Finland can become carbon sinks within just 15 years of restoration, suggests a study published in Restoration Ecology."
Restored peatlands can become habitats right away and stop harmful discharge to the rivers and lakes.

We have to insulate >9 billion square meters until 2050 in the EU.
I don't think it needs many brain cells to realize that this needs to be done with regenerative materials like straw; which is available and cheap instead of fossil, synthetic materials.

Every straw panel factory could take a byproduct of local agriculture (wheat straw) and produce 40,000m² of panels every year, locking up 4,000 tonnes of CO₂e
For comparison, an average carbon footprint of a person in UK is 10 tonnes of CO₂e per year

Freue mich sehr auf den Vortrag. Damals wurde ich belächelt als ich in Unis/Berufsschulen zeigte, wie #Lehmbau geht. Damals brachte ich meine Gartenerde mit. Nun sind ehemalige Teilnehmehmende in der ganzen Welt @ #Bauwende unterwegs. Bin froh Teil des Wegs zu sein.

In the midst of a climate crisis and the sixth mass extinction, it should be the bare minimum of responsibility to build data centers climate-neutral. This applies not only to their operation, of course, but also to their construction.
