Tons of CO₂ offset

### Mati Carbon

Mati Carbon spreads abundant, locally sourced crushed rock on rice paddies, accelerating the natural weathering process in which rock absorbs carbon dioxide.

### Pacific Biochar

Pacific Biochar uses a process called pyrolysis to convert sawmill and forest residues into biochar, a carbon-rich charcoal.

### Carbon Removal Alliance

Carbon Removal Alliance works to advance policies that support a diverse set of permanent carbon removal technologies.

### Graphyte

Graphyte removes CO₂ from the atmosphere by taking residual or waste biomass leftover from timber and agricultural operations and producing carbon blocks that are stored safely underground.

### UNDO

UNDO accelerates the rock weathering process by spreading crushed silicate on farmland, providing it immediate contact with carbonic acid from the rainwater.

### Charm Industrial

Charm Industrial collects biomass residues and converts them into a stable, carbon-rich liquid called bio-oil.

# We fund CDR projects based on nine diligence criteria.

#### Credible pathway

Research demonstrates science-backed proof of concept of the pathway.

#### 1,000+ yr. durability

There is broad scientific consensus that carbon is removed and durably stored for over 1,000 years.

#### Climate equity

Projects are inclusively designed and implemented and align with environmental justice principles.

#### Additionality

Activities are not required by law and are not widely implemented today.

#### Mitigation of externalities

Plans are in place to ensure ecosystems and communities are not harmed.

#### Maximized co-benefits

Activities contribute to Sustainable Development Goals and do more than remove carbon.

#### Financial self-sufficiency

The company has a plan to make money – through the sale of carbon credits or otherwise.

#### Policy alignment

Activities are aligned with national and international climate policy – such as the Paris Agreement.

#### Technological readiness

The company is working on research, feasibility, and demonstration to reach sub-$100 cost per tonne.
