About
NBS Integrity Co. provides independent, customized due diligence for nature-based carbon offset projects. We help buyers, investors, and procurement teams make confident, evidence-based decisions by evaluating the real integrity, risks, and benefits behind forest, soil, wetland, and agroforestry carbon claims.
We combine deep technical knowledge of registry methodologies with an understanding of real-world implementation: land governance, ecological dynamics, and social context. Our assessments examine the full spectrum of project quality — including baseline credibility, additionality, leakage risks, permanence, and the depth of biodiversity and community co-benefits. We recognize that true offset quality is not just about carbon — it's about impact that endures.
Unlike large consulting firms or ratings platforms, we deliver rapid, fit-for-purpose assessments tailored to each client’s needs. Our reports are designed to be decision-ready — providing clarity and actionable insights without the cost and complexity of full-scale audits or subscription-based ratings. Whether you need to screen a single REDD+ project or compare a diverse portfolio, we deliver independent evaluations built around integrity, transparency, and practicality.
We operate independently. We don’t develop, promote, or broker carbon credits. Every assessment is bespoke, built for clients who seek more than reputational cover: they seek real impact, verified by objective, transparent evaluation.
Our Frameworks
At NBS Integrity Co., our due diligence evaluations are built on structured, proprietary frameworks developed specifically for nature-based carbon offset projects. We combine scientific rigor with market relevance to provide independent, in-depth assessments. Our frameworks are continuously refined to keep pace with the evolving standards and expectations in the voluntary carbon market, ensuring that projects are assessed against the most current and credible benchmarks. By maintaining this alignment, we provide clients with evaluations that reflect the latest technical requirements and market trends, supporting decisions that stand up to increasing scrutiny from buyers, regulators, and stakeholders alike.
How we evaluate projects
Comprehensive Indicator Set: Every project is evaluated against a framework of more than 80 carefully designed indicators. Each indicator is assessed based on evidence strength and risk exposure. This structured system allows us to surface material risks and strengths consistently across different project types and geographies, ensuring a comprehensive and transparent assessment for clients.
Geospatial & Remote Sensing Analysis: We conduct independent geospatial analysis to validate key project parameters and reported outcomes. We also evaluate the uncertainty in geospatial data, providing clients with a clearer understanding of data limitations and confidence levels.
Carbon Integrity: We undertake a detailed review of the carbon accounting frameworks underpinning each project. This includes evaluating baseline scenario credibility, testing additionality claims against regulatory and market baselines, and reviewing strategies for leakage prevention and quantification. We also assess permanence risks, including the adequacy of buffer pool contributions relative to reversal threats. Our carbon assessments are benchmarked against emerging principles like the ICVCM Core Carbon Principles. This ensures that carbon claims are scientifically robust and market-aligned.
Risk Analysis & Materiality Mapping: Our evaluations apply a multi-dimensional risk framework that examines environmental, operational, and financial risks. Environmental risks include threats such as fire, pests, and climate change impacts, while operational risks assess implementation challenges and monitoring performance. Financial and market risks consider project revenue stability and exposure to market fluctuations. Risks are evaluated for both likelihood and materiality, providing clients with a clear understanding of which risks are most critical to project success and carbon credit performance.
Co-Benefits & SDG Contributions: Beyond carbon, we evaluate the credibility and evidence base of claimed biodiversity, community, and Sustainable Development Goal contributions. Our reviews assess the quality of data supporting biodiversity conservation outcomes, the robustness of community engagement and benefit-sharing practices, and the alignment of project activities with relevant SDGs. Claims are cross-checked against project documentation, third-party reports, and independent datasets such as biodiversity surveys and socio-economic statistics where available. This ensures that co-benefit claims are not only well-documented but also verifiable.
Governance and Transparency Review: We conduct thorough reviews of governance frameworks to assess the legal security of land tenure, the transparency and fairness of benefit-sharing arrangements, and the effectiveness of stakeholder engagement processes. Particular attention is given to the existence of free, prior, and informed consent (FPIC) practices, as well as the accessibility and impartiality of grievance mechanisms. Our reviews draw on project documentation, independent verifications, and third-party assessments where available. By evaluating governance structures alongside project implementation, we help clients identify potential social and operational risks that could affect project durability, reputation, and overall integrity.
