Introducing methodology assessments: independent benchmarks for carbon frameworks

Methodology selection is one of the most common early-stage decisions in both the carbon project development journey and the project due diligence process. Every project is inherently shaped by this choice. 

Before capital is committed, before credits are issued, and before climate claims are made, investors, project developers, and buyers must decide which standards body and methodology will govern the project’s design and verification. That choice influences how additionality is tested, how baselines are constructed, how emissions are measured, and how permanence risks are managed. It can also affect regulatory eligibility, long-term bankability, and buyer confidence.

Whether a methodology incorporates the latest in digital monitoring, reporting and verification (dMRV), relies on credible counterfactual models, applies dynamic baselines, or adopts conservative risk buffers has a material impact on a project’s carbon efficacy. Understanding how these design choices can influence risk is critical to navigating an increasingly sophisticated market.

With over 1300 project assessments across sectors delivered by one of the largest in-house science teams in carbon markets, BeZero Carbon is uniquely positioned to bring independent risk analysis to that step. That’s why we now offer methodology assessments to complement our project-level ratings.

How can a methodology assessment help you?

Methodology-level risk affects practical decisions across the carbon value chain. The BeZero Carbon Methodology Assessment can streamline this decision-making, particularly at the project ideation and feasibility steps.

• Project developers compare, select, or switch methodologies at the earliest stages of project design, with material implications for credit volumes, financing prospects, and market acceptance. Getting an upfront signal on a methodology’s robustness can pre-empt problems down the line.

• Investors often screen opportunities by methodology exposure before committing resources to deeper project-level analysis. A methodology assessment can be the first step in de-risking project performance.

• Standards bodies, whether established institutions or emerging innovators, may seek independent external scrutiny to strengthen methodological robustness, benchmark themselves against peers, and support go-to-market activities.

• Experienced buyers prioritise science-based frameworks to reduce reputational and integrity risks, and this often starts with a thorough assessment of a project’s methodology.

• Governments and regulators setting the eligibility criteria for Article 6 or domestic compliance schemes typically operate at the methodology level.

Across these roles, the need is consistent – independent and science-led insight into the strength of the rules that will govern a project, before capital and credibility are put at stake. 

For example, Equitable Earth, a global standard for conservation and restoration projects, asked us to review one of their forestry methodologies. Our analysis gave them food for thought on how their methodology could go even further to ensure high-integrity projects, and ultimately increase buyer confidence.

"BeZero Carbon's assessment of M001, our methodology for terrestrial forest restoration, was rigorous, balanced, and fair. And while we are content with the 'Low risk' tier, their analytical team’s deep expertise in nature-based projects highlighted meaningful opportunities to strengthen the methodology further."

A benchmark of methodological robustness

BeZero’s methodology assessments evaluate the risk and robustness of carbon crediting methodologies themselves, rather than individual project implementation.

We’re uniquely placed to conduct such assessments for a number of reasons:

• A track record of 1300+ project assessments across methodologies built by 20+ accreditors, across sectors and geographies

• An experienced, multidisciplinary team of 80+ in-house analysts behind every assessment, with backgrounds in Earth sciences, nature-based solutions, engineered carbon removals, geospatial analysis, finance and climate policy

• A holistic approach to assessing both carbon and non-carbon risks, with detailed, sector-based methodologies that are always open to public scrutiny

• A reputation for independence, with no vested interests in rating outcomes or transactions, no MRV consulting, and no project development, trading or advice

Each methodology assessment produces a five-tier risk score ranging from ‘Very Low’ to ‘Very High’. 

We evaluate risks supported by qualitative analysis of strengths and weaknesses across the same three carbon risk pillars we use in our project-level ratings, as well as a fourth pillar on governance and transparency, which evaluates the rules and processes around oversight and disclosure.

By focusing on the rules embedded in a methodology, we provide a consistent and comparable benchmark across sectors and standards. This can act as a minimum threshold quality gauge for stakeholders who want to understand framework-level risk.

By popular customer demand, we’ve already completed assessments across nature-based methodologies, including Afforestation, Reforestation & Restoration (ARR) and soil-related agricultural practices, as well as technology-based protocols for Cookstoves and Bioenergy with Carbon Capture & Storage (BECCS).

Going deeper with project-level ratings

While offering a useful first step in thinking about project quality, our methodology assessments are not a replacement for the BeZero Carbon Rating. 

Methodologies may be well-defined, but projects can diverge in practice, leading to significant differences in credit risk. Implementation choices, local context, monitoring practices, data quality, and baseline assumptions can materially influence whether credits are likely to deliver their intended climate impact. Two projects operating under the same methodology can present very different risk profiles.

BeZero Carbon Ratings assess these project-specific factors in detail. A full rating involves independent analysis by our ratings scientists and policy analysts, supported by geospatial tools, proprietary models, and peer review by BeZero’s Rating Committee. It provides a granular view of carbon efficacy risk that cannot be inferred from a methodology score alone.

Simply put, a robust methodology may signal but does not guarantee a high-quality project. 

Complementary assessment tools

BeZero’s methodology assessments complement our ratings: they evaluate the strength of the framework underpinning credits, while our ratings analyse how projects apply those rules in practice, and the likelihood of delivering their promised carbon avoidance or removal.

By offering both methodology assessments and project-level ratings, we enable customers to engage with carbon risk at the level that best fits their needs – whether that is benchmarking frameworks, scrutinising individual projects, or combining both for a comprehensive and layered understanding of risk.

Methodology assessments that we’ve delivered are available to BeZero’s platform customers. To access them, or request a methodology assessment, get in touch. If you're a platform customer, you can find them here.
