Love for Life.

Working at the seam between systems thinking and systemic intervention. The brief, in one line: find leverage, and use it to bring new patterns into being. The page below is what that looks like in practice.

Currently building
Climate Cleanup · Oncra · and a third strand not yet described in public — see § 03.

The premise.

A simple operating premise, held to be obvious until argued out of: the things worth doing are the things that produce more life — more living beings, more living relationships, more conditions in which living things can flourish. Not a metaphor; a criterion. Held against most decisions, it tells you which way to go.

Whitehead’s claim about novelty, taken at face value: the universe’s creative advance proceeds by the introduction of patterns that did not previously exist, and human beings are, by some accident, unusually well-equipped to introduce them. That’s the work. The rest of this page is what it looks like.

Method.

Look for leverage. Donella Meadows’ observation — that systems can be moved by very small interventions in the right places, and almost not at all by very large interventions in the wrong ones — has been a steady companion for years. Most of the work is figuring out which is which.

Then take Buckminster Fuller’s instruction about method seriously: don’t change things by fighting the existing reality, build a new model that makes the old one obsolete. The discipline is to keep doing that — patiently, in small cells, with people you trust — until enough of the new model exists that the old one quietly stops being the centre of gravity.

You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete. R. Buckminster Fuller

Climate Cleanup.

Co-founded in 2018, with a small group of entrepreneurs who, rather than waiting for permission, had already started removing carbon with nature. Climate Cleanup Foundation now organises a connected network of removers across construction, agriculture, land, ocean and rock — operating against a frankly absurd target of 1,500 gigatons of CO₂ drawn down by doubling nature, on the reasoning that this is, while emissions are stopped, what is actually needed.

The class of solutions Climate Cleanup works on shares one property: the act of building and farming is the act of removing carbon from the atmosphere. Biobased buildings whose materials drew down carbon as they grew. Roads bound with grasses rather than refined fossils. Forms of agriculture and rock weathering that store carbon as a property of doing the underlying work well. The carbon arithmetic stops being a sacrifice and starts being a property of the architecture.

Some of the work happens in the policy layer — the European Commission’s Carbon Removals and Carbon Farming framework (the CRCF) and its Dutch implementation — because the rules that decide what counts as carbon removal will decide a great deal more than that.

Oncra.

Oncra — the Open Natural Carbon Removal Accounting initiative — is the piece of infrastructure that sits underneath that policy work. Built inside Climate Cleanup with ASN Bank as founding partner, on a deliberately Open, Simple and Symbiotic philosophy: a public registry, peer-reviewed methodologies, and certification protocols that anyone can read. Currently CEO; lead author on several of those protocols.

Removing a tonne of CO₂ is a physical act. Counting it, certifying it, and trading it is an institutional one — and unless that institutional layer is credible, the physical layer cannot reach the scale the atmosphere requires. Oncra now certifies removals across construction-stored carbon (most recently with a.s.r. real estate, for a hybrid timber building in Amsterdam’s Zuidas), land-stored carbon (bamboo, regenerative agriculture), and rock-stored carbon (enhanced weathering of olivine).

A third strand, not yet public.

The largest in ambition, and not yet ready to describe. What can be said now is the shape of the wager.

The most direct route through the climate crisis is not to fight the existing society into changing, but to grow a different one alongside it — one that is, by Buckminster Fuller’s plain measure, simply better at being a society. Better in the sense of producing more life and more love, with less violence done to either. The carbon arithmetic, on this approach, is not the goal but a consequence: a society whose buildings are made of plants and whose food systems leave the soil heavier in carbon than they found it removes carbon by the act of being built. Climate becomes a side-effect of civilisation done well.

A habit of starting.

The pattern across the years matters more, perhaps, than any single project. Each entry below began as something that didn’t yet exist, and was put into the world to see what it would do. Some aged into ongoing work; some were one-shot interventions; all of them taught something about the texture of the systems they touched.
