The Proven Climate Solution that doesnt need any EU grant.

I’m writing this from Sérignan, in the south of France – where the land slowly leans to the Mediterranean and the air smells like salt and wild herbs.

Here the oaks are not the big giants you maybe imagine. In the dry, tough Mediterranean scrubland you find holm oaks and kermes oaks. They don’t stand in neat lines, they don’t ask for attention. They just survive. Season after season. Year after year.

Some of them stood here for hundreds of years, watching empires come and go, storms hit the coast, vineyards change hands. Quietly they do their job: giving shade, storing carbon, helping other life to grow.

When I walk here, I can’t help to zoom out. Not only in space, but also in time.

And then you start to wonder…

If we remove politics, egos and market thinking, and just ask:

‘What’s the most effective, low-cost way to fight climate change?’

It’s hard to beat planting trees.

You put them in the ground. You wait. They catch carbon, bring back biodiversity, hold the soil together, balance water cycles, and make our planet more liveable – in ways we still don’t understand fully.

It’s simple. It works. And it’s been working for millions of years without one single EU grant application.

And still…

We don’t do it at scale.

Not really.

Not in the way we could.

Because our systems (economic, political, cultural) are built for speed, measurability, marketability. We like solutions you can put in a quarterly report, sell as innovation, and get investors excited about in a hockey-stick growth graph.

A slow-growing oak doesn’t fit in that picture.

It doesn’t give press releases every six months.

You can’t IPO a forest.

So we put billions in technologies that you can brand, patent, and pitch. And we ignore the slow, quiet, not-so-sexy solutions standing right in front of us.

Maybe the problem is not that we don’t know what works.

Maybe the problem is we don’t have systems that let the things that do work win.

And maybe, building a healthy economy is a bit like growing an oak forest: it needs patience, the right conditions, and a community of roots under the surface – invisible to most, but essential to all.

Happy summer holidays, y’all.
