RyeStrategy’s GHG Calculator Is Now UL Verified
A significant milestone that validates our commitment to data accuracy and quality services for our clients.
We are pleased to announce that RyeStrategy’s GHG Calculator has been UL Verified, confirming through independent review that our methodology, managed content and control environment meet the expectations of a standards aligned reporting tool. This is an important milestone for the platform and reinforces the confidence our clients place in the calculations they use for Scope 1, 2 and 3 reporting.
For many organizations, especially small and mid sized suppliers, the validity of the GHG calculator used to calculate Scope 1, 2, and 3 emissions matters. As procurement requirements become more stringent and companies face verifications and audits, a third-party verified GHG calculator reduces uncertainty and strengthens the quality of reported climate data.
What our clients can expect going forward
For our clients, the GHG calculator within the RyeStrategy platform remains the same guided, consultant supported platform built for clarity and reliability. Your user experience is unchanged. The UL verification simply reinforces the foundation behind it, ensuring that clients continue to have a trusted way to measure and communicate their greenhouse gas emissions.
“Achieving UL Verification is a powerful affirmation of the accuracy and integrity behind RyeStrategy's GHG Calculator. This milestone strengthens our ability to serve small and medium-sized businesses with the confidence, clarity, and exceptional service they deserve.”
Hannah Moskowitz, Sustainability Director

Why this matters for our clients
Clients rely on the calculator to prepare information for disclosures, procurement processes and internal reporting. UL verification helps demonstrate that the platform is grounded in a clear and transparent foundation, including:
Alignment with the GHG Protocol Corporate and Value Chain Standards
Independent evaluation of calculation logic and managed content
Controls that support consistent and defensible reporting
Reduced risk of questions about the tool during reviews or audits
This verification supports clients as expectations grow around greenhouse gas reporting and the integrity of the data behind it.
What UL evaluated
RyeStrategy engaged UL Solutions to complete an independent verification in alignment with ISO 14064 3. The review was conducted at a limited level of assurance and focused on the core components that influence the accuracy of emissions outputs.
UL reviewed:
How the GHG accounting methodology is applied within the calculator
The accuracy and availability of emission factors and conversion factors
Controls that guide data entry, review activity and error detection
Sample calculations across Scope 1, Scope 2 and Scope 3 categories
In its verification opinion, UL found no evidence that the methodology, managed content or control environment are materially incorrect when the calculator is used with inputs that are free from material error and reviewed by a RyeStrategy consultant.
Supporting audit ready reporting
The UL verification confirms that the calculator is designed to support consistent, defensible results across a wide range of reporting scenarios. For clients preparing for audits, supplier requests or disclosure cycles, this provides additional assurance that:
Calculations follow established guidance
The underlying system has been independently reviewed
Managed content is maintained with accuracy in mind
Consultant support adds an additional safeguard for data quality
RyeStrategy has always been committed to data quality and accuracy. This UL verification confirms that our emissions calculation and reporting process meets the expectations of our clients. We are committed to continuing to enhance our methodology, content and controls as climate data reporting needs evolve.
