Our Methodology: Ensuring Trust, Transparency, and Real Climate Impact.

At Hestiya, we believe that credibility is the cornerstone of a trusted carbon market. Every project listed on our marketplace undergoes a rigorous selection process designed to ensure authenticity, measurable impact, and alignment with the highest global standards.

Building a Credible Carbon Market

Today’s carbon markets struggle with credibility due to low-quality projects, double counting, and lack of transparency. Many offsets fail to deliver real impact, either because reductions would have happened anyway or aren’t properly verified. Hestiya solves these issues with a strict, transparent methodology that ensures every project is additional, measurable, and independently audited. Each credit is fully traceable, giving supporters clarity on its origin and impact. Beyond emissions, Hestiya-backed projects also benefit local communities, helping restore trust in carbon markets and driving meaningful, lasting change.

Our Project Selection Process

Step 1: Initial Screening

We review the project’s alignment with leading global standards such as Verra, Gold Standard, and Evident, as well as its contribution to the UN Sustainable Development Goals (SDGs).

Step 2: Documentation Review


We thoroughly analyze project documents, validation reports, monitoring reports, and issuance certificates to assess transparency and legitimacy.

Step 3: Third-Party Verification Check


We verify that the project has been validated and verified by accredited independent organizations, ensuring it meets international best practices.

Step 4: Impact Assessment


Beyond carbon removal, we assess the broader social and environmental impacts — including community benefits, biodiversity conservation, and contribution to sustainable development.

Step 5: Risk Analysis


We evaluate risks such as permanence, leakage, additionality, and potential double counting, ensuring projects offer true environmental value.

Step 6: Final Approval & Listing


Only projects that pass every stage of our due diligence process are approved and listed on the Hestiya Marketplace, ready for your support.

What We Look For

At Hestiya, we apply six key criteria to every project before it’s listed on our marketplace:

Integrity


We only work with projects verified by globally recognized registries such as Verra, Gold Standard, and Evident. This ensures each project meets the highest standards in the carbon market.

Additionality


Projects must deliver carbon benefits that wouldn’t have happened without the support of carbon finance. If it would’ve happened anyway, it doesn’t count.

Permanence


We assess whether the impact will last. Projects must include long-term carbon storage or mitigation strategies to reduce the risk of reversal or loss.

Transparency


We require full public access to documentation, monitoring reports, issuance data, and verification records. This allows buyers to make fully informed decisions.

Co-benefits


We prioritize projects that also support local communities, protect biodiversity, and create social and economic value beyond just carbon removal.

Alignment with Global Standards


Where possible, we ensure projects are aligned with the Core Carbon Principles defined by the Integrity Council for the Voluntary Carbon Market (ICVCM), raising the bar for quality and trust.
