Our certification

Unlocking the international voluntary carbon market for smallholder farmers by streamlining the certification activities as a program.

Our agroforestry projects are certified with Plan Vivo, an independent certification body that specializes in smallholder forestry projects. As a leading certifier in community land-use projects, they work with us to ensure our projects are truly benefiting farmers, their land, and the environment.

How we make certification more accessible 

To successfully certify a project and the CRUs generated, each project undergoes a thorough initial assessment to measure eligibility and additionality, alongside collecting a range of baseline data.

We recognize, however, that certification is not always easy for project coordinators or accessible for smallholder farmers. So we've made our certification process as straightforward as possible: our framework and methodology keep the certification process accessible and transparent, while reducing the costs and lead times of certification significantly. For example, we define and monitor only a few impact indicators (local livelihood, carbon storage, and environmental improvement).

Our framework and methodology

Our certification approach and the requirements that projects must adhere to are described in the Acorn Framework.

The complementary Acorn Methodology describes the processes involved when measuring and calculating CRUs. The Methodology has been externally assessed and approved by the Plan Vivo Foundation and an accredited validation and verification body: AENOR.

Now available is the latest methodology and errata to describe improvements and corrections made going from Methodology Version 1.0 to Methodology Version 1.1.

Why validation and verification are important

Validation and verification are critical to ensure the credibility and effectiveness of our projects. Validation is the initial assessment to confirm a project's design and expected outcomes, while verification measures and evaluates the actual results post-implementation. These processes provide transparency and accountability to help ensure our projects deliver real climate and community benefits. By adhering to rigorous standards, we can build trust with farmers, partners and buyers.
