Message History

We’ve just published a new preprint that asks a very practical question for enhanced weathering (EW): if plants grow more after rock dust application, could that be an early indicator that carbon dioxide removal (CDR) is happening?

EW has a welcome “two-for-one” promi...

What Two Years of Data Reveal About EW Performance

Over the past two years we have run the largest controlled greenhouse experiment for enhanced weathering that we know of. With hundreds of pots, multiple soils, and a wide range of rock types, the goal was straightforward. We wanted to understand how rocks behave in real soil environments and which co...

Why MRV Is the Backbone of Trust and How We Actually Prove the Carbon Is Gone

Parts 1–3 explained the inputs: emissions, boundaries, and smarter material choices. Catch up with these links: Part 1,

This series highlights the companies Carbon Drawdown Initiative has invested in.

What if a powerplant didn’t just avoid emissions but actively removed carbon from the atmosphere while producing clean energy? SYNCRAFT has been working toward that reality for m...

A new and interesting paper from Jelle Bijma et al. was published today (and we helped a bit over the last 5 years to do the science behind it).

What the paper says

Enhanced Rock Weathering (ERW) sounds simple on paper: spread crushed rock on fields, the rock slowly dissolves, and part of the CO₂ ends up stored as dissolved bicarbonate in water that eve...
