Permanent climate fieldwork

The durable carbon standard

Climate work measured in centuries.

We fund durable carbon removal and publish the evidence in the open.

01 / Our standard

Our planet needs permanent carbon removal—at field scale.

What permanence means

At Fieldnote Summit, we support carbon removal that can be measured, traced and held accountable for generations. We back practical pathways, then share what worked so the next project starts further ahead.

Each commitment is reviewed against three simple ideas: a real tonne, a durable home and a record anyone can inspect.

A tax-deductible vehicle for ambitious field trials.

How it works

Fieldnote Summit is an independent nonprofit funding early, measurable climate infrastructure. Contributions pool into milestone-based grants, technical review and shared learning—so donors can support the difficult first deployments without building a program from scratch.

47Active field reviews across four removal pathways
✓Independent technical and community diligence
