Our Approach

Equitable Business Model

We commit a 50% share of gross carbon credit income to local communities, and a further share with our local distribution partners.

50% Gross share to farmers, local communities
for Verified project contributions
Verifiable via Digital Payments
Latest Message from CEO

Arukah was established during the pandemic amidst predictions that up to 100 million people across Asia might fall below $2 a day—many of whom are farmers.

Fast forward to 2024, we have gone live on two critical project blueprints that we aim to scale across the Global South with carbon markets and cutting edge digital sensors and payments infrastructure.

As we prepare for 2025, I want to thank our team, partners and investors for believing in, joining and persevering on our vision—of smallholder farmers and the Global South as critical partners in high quality, Gigaton-scale decarbonisation and carbon removal.

We closed the year with a first in the world blueprint for household biogas from farmer-level real-time tracking to verifiable digital payments to farmers—featuring 100% tracing and majority revenue share for farmers and local ecosystems, to our knowledge the first in market in over a decade for this Corsia compliant methodology. We are also soon commencing the commissioning of a large biochar plant in Cambodia, which will be a blueprint for our biochar at scale—diverting waste burning, and unlocking improved productivity and access to new incomes.

We look forward to partnering with you—and many more—in the coming year ahead. Here's to a restful close to 2024, and an exponential 2025 ahead!

About us
Our Values
Innovation
Climate and agrifood are complex and rapidly evolving, so we aim to stay fresh and ahead of the curve. We are constantly learning about and testing the latest in (i) technology; (ii) data analytics; and (iii) methodologies - and anything else that might come up.

The more we can reduce MRV costs and improve the quantity and verifiability of carbon capture and storage, the higher our margins—and the more farmers can benefit from our model, sustainably and at scale.
Excellence
We approach all projects as decade-long institutional grade projects.

Since our time horizons are long, we invest in strong foundations and partner with the best—even if upfront costs are higher.

We engage the best technology, partners and researchers globally and locally. We also proactively engage governments, registries and buyers, and anchor all partnerships with rigorous legal contracting across carbon rights, data use, implementation partnerships, and more.
Verifiability
We only claim what we can back with transparent, 3rd party verifiable data.

Our emissions removals and reductions calculations are aligned with best in class registries and digital MRV is conducted in partnership with the registries directly.

On co-benefits we are starting with 2-3 fully-verifiable SDG claims across financial inclusion and food or gender. So, even if our projects do feature other co-benefits, we are conservative about making these claims without granular and rigorous data.
