In the early years at Paessler, around the turn of the millenium, there was no separation of roles. I “was” the company and I was the only employee, and whatever needed doing next was what I worked on.

I am a graph nerd and I love graphs like this. This multidimensional graph from our two-year dataset of the largest greenhouse experiment for enhanced weathering gives us multiple insights for EW projects.

SYNCRAFT is one of the most compelling examples of what climate-positive energy can look like when engineering meets regional circularity.

Recently I wrote about the first “click” at age 12, the moment a demo computer in a department store flipped a switch in my brain. What happened next was even more important: building became its own engine. I didn’t need motivation, encouragement, or a plan.

With the year coming to an end it’s time to look back what happened this year with indoorco2map.com and even more importantly what the goals for next year are: a big app overhaul, support for stationary sensors providing live data, more community events and more collaboration. Details below ↓

My most recent poll was answered by 85 people: 80% of you believe that the current funding slowdown in climate tech will continue for more than 2 years or even more than 3 years. Less than 10% are optimistic for the next 12 months, another 11% hope for 1-2 years.

This is a positive surprise to me! 95% of voters in my poll last week think that Enhanced Weathering (EW) is "economically viable".

Enhanced rock weathering gets even more carbon-efficient when you use the material we already have.
In Part 3 of our “Lifetime Carbon Balance of ERW” series, we look at one of the biggest levers for improving net-negative outcomes: waste rock, quarry fines, and mine tailings.

We all look for any good climate news we can get this year. Here is one: I’m proud to share that InPlanet – one of our portfolio companies at Carbon Drawdown Initiative – is partnering with Microsoft to remove an impressive 28,500 tonnes of CO₂ via Enhanced Rock Weathering (ERW) from 2026-2028.

Covid-Modell-Situation (13.12.25):
Eine BA.3.2-Welle setzt sich auf die XFG-Welle (Grafik). Durch den Rückgang der Kontakte wird sie vermutlich um Weihnachten brechen, bleibt aber bis Mitte Januar hoch.
Das Variantenmodell für BA.3.2 ⇒ bsky.app/profile/mart... ist noch nicht stabil.

COVID-Hospitalisierungen der @dgina.bsky.social Notaufnahmeampel zeigen wie von @rv-enigma.bsky.social gesammelte Daten, dass wir über Weihnachten in einer COVID-Welle sein werden. Die Inzidenz-Abschätzung (!) in der zweiten Grafik zeigt, dass sich das auf dem Niveau von 2022/2023 bewegen könnte.

What does a Life-Cycle Assessment actually measure in enhanced rock weathering, and why does it matter?
This is one of the most important questions in ERW, because a carbon credit is only as good as the accounting behind it.

We are entering the CDR 3.0 world. And that's a good thing. Let me explain.
I recently heard Chris Sherwood, Secretary General of Negative Emissions Platform, explain the three phases of CDR that we have seen over the last maybe 10 years. It goes something like this:
