Ukraine is Europe! We stand by Ukraine. We will step up our support to Ukraine so that they can continue to fight back the agressor. Today, it became clear that the free world needs a new leader. It’s up to us, Europeans, to take this challenge.

"cooling within a decade"... with carbon storage in construction products from fast growing plants. Seems like a nobrainer to me, am I crazy? LET'S DO THIS. You can't? Ask. journal-buildingscities.org/…

Seems we've made it.🙌 EcoCocon has been featured in Financial Times. A well written introduction to our system, as well as straw's massive potential as an untapped, renewable and widely available resource.🌱 ft.com/content/b1709f76-0995…

We should build a new presidential office in the shape of a giant upside down pyramid! Sure, they’ve built normal pyramids before, but a giant upside down pyramid? That takes advanced technology.

Today we have a sneak peek of something very special brewing over in Sweden.👌 Perhaps you’ve heard of the popular British TV show Grand Designs? Well, this straw beauty will be the main star of an episode of the Swedish version of the show.🌱 1/2

Thought I would check out ChatGPT to see how well versed it is in straw bale building. Disappointed at first, but my mistake asking the wrong question!😂

This morning, @CBSMornings ran a story on gas stoves to 2.5 million viewers. Did they mention gas stoves increase the risk of asthma? No. Did they question a gas industry rep who claimed gas is "clean and safe"? No. Instead they spread fossil fuel industry lies. 🧵

The ruling is in.⚖️CO2 was found guilty of crimes against climate. 3 815 755 kg of CO2 are now serving a life sentence, imprisoned in the walls of EcoCocon homes. Straw captured the suspect, who was trying to escape into the atmosphere. 39,000 m2 of walls built and counting 💪

As a good parent company, we love all our projects equally. But gun to our heads, we’d have to go with Old Holloway.🏡The straw cottage is still a stand-out example of passive design. Check out our interview with owner-architect George Mikurcik👇 ecococon.eu/blog/2021/interv…

Observed temperature changes for 196 countries around the world paints a stark picture. Everywhere is warming. Risks from heatwaves are increasing. Impacts on people & ecosystems are intensifying. Halting the warming requires rapid cuts in carbon emissions.

I just added my name to this emergency appeal for climate action by Greta, Vanessa, Mitzi, and Dominika. Sign now and share, and they'll deliver our voices directly to governments at the @COP26 #climate summit. fb.avaaz.org/campaign/en/cli…
