AI-assisted checks: 10 of 15 found evidence in the excerpt read for their principle, each citing the paragraph it came from.
Tested on 177 labelled questions from 11 projects (short 2,500-character excerpts), the checks were right 94% of the time (95% interval 89%–96%). Reports read longer excerpts, which find more: of 61 findings the short excerpts missed, 46 were confirmed (75%, judged by an AI reviewer, who agreed with a person on 18 of 19 spot checks). How this was measured.
Robustness: deleting the paragraphs that held the evidence turned 87% of “found” answers to “not found”, and unrelated text got “not found” on 177 of 177 questions. A paragraph planted in the document telling the model to answer “yes” changed 0 answers; one telling it to answer “no” changed 71%, which is why such paragraphs are screened out before a model reads the excerpt (the screen is a pattern match and can miss new wordings). Robustness tests.

“1 PROJECT DETAILS 1.1 Summary Description of the Project Summary description of the technologies/measures to be implemented by the project: ‘DelAgua clean cooking grouped project in Rwanda’ is a voluntary Grouped Project (GP) aimed at distributing fuel efficient improved cookstoves (ICS) to households in Rwanda. The Project Participant (PP) of the GP for all the communication, management, and ownership rights of the Greenhouse Gas (GHG) Emission Reduction Units (ERU) is DelAgua Health Rwanda (Voluntary) Limited (DelAgua) and the ICS under this GP will be distributed by DelAgua. The distribution of ICS is not mandated by Rwandan law and the Grouped Project is a voluntary initiative being run by the PP DelAgua. The program is not being implemented as a result of any government legislation or intervention. Throughout this Project Description, this grouped project may be interchangeably referred as “program". The PP plan to distribute 400,000 improved cookstove under the grouped project during first renewable crediting period. It is intended that under this GP two types of single pot portable stoves will be distributed, which are SSM S32 X stove and Burn Kuniokoa G21. Each household will receive 1 ICS. The location of the project: Under the GP, DelAgua will distribute the project technologies to individual households and communities within the host country Rwanda. The PAIs will occur in geographically defined regions within Rwanda. The details of the GP and PAI locations are provided in Section 1.13 of this document. All households will be in rural areas of the identified regions in section 1.13 of this document. Implementation Dates: Full details of implementation dates and numbers for each PAI under the GP are laid out in section 1.12 of this document. An explanation of how the project is expected to generate GHG emission reductions or removals: The GP will follow the VCS Methodology from Sectoral Scope 3 - VM0050 “Energy Efficiency And Fuel-Switch Measures In Cookstoves”, version 1.0 for ER calculations. The implementation (distribution of ICS units) and parameters set for ER calculations within the GP will be monitored on a periodic basis, based on the requirements provided within the applied methodology. The cookstove project in Rwanda will reduce GHG emissions by replacing inefficient traditional wood-fuel cookstoves with high-efficiency ICS units. By improving combustion efficiency and reducing firewood consumption, the project will reduce equivalent GHG emissions from incomplete combustion and help prevent deforestation. Additionally, the project will improve indoor air quality, reduce fuel costs, and enhance community well-being, contributing to both climate change mitigation and sustainable development. A brief description of the scenario existing prior to the implementation of the project:”
Emission-avoidance activity without stored carbon at risk of reversal; permanence is not applicable (rule based on project category, not AI).
Not scored for this activity type (no reversal risk).

“Purpose of data Calculation of baseline and project emissions Calculation method The value of 0.8872, registered in the Project Design Document (PD) under TOOL30 Version 4 for Rwanda, is adjusted to account for uncertainty in accordance with VM0050. A 26% uncertainty discount is applied, resulting in the following adjusted value: 0.8872 × (1−0.26) =0.6565 Comments This data has been fixed for entire crediting period. The applied fNRB value has been calculated by using the latest available data sources. As per the fNRB calculation done by PP, the value is 91% however as a measure of conservativeness, PP used the fNRB value from another registered projects which was lesser than 91%. Hence, the value has changed to 88.72% and finally to 0.6565 with uncertainty discount consideration.”
“Calculated as per the “TOOL30: Calculation of the fraction of non-renewable biomass” and applying an uncertainty discount of 26% in accordance with applied methodology”
“Purpose of data Calculation of emission reductions Calculation method This parameter is calculated by multiplying the proportion of operational stove identified during monitoring surveys with the total number of ICS distributed under the project activity. Comments This parameter only accounts for the number of project ICS that are operating in the monitoring period, and rest of the factors such as discount on non-usage of project ICS, usage of pre-project device, and drop-off are accounted separately, and hence are not reflected with the values provided for this parameter. Here, the batch j is not segregated in a PAI. Every distribution under a PAI may be considered as a separate batch. For this monitoring period, PP has also utilized data from educational and training visits to calculate this parameter as it gives the most conservative value. PP has provision of continuous revisiting of households for educational and training purpose as per Section 6.3 of the Registered PD. However, out of 548,327 ICS distributed to the households, a visit to 12,759 households who were the beneficiaries of stoves in this monitoring period were not been completed. For more details see section 3.1. Therefore, as a conservative measure, PP has considered these 12,759 ICS as not operational and applied the operational fraction to the population of the respective PAIs, as shown in the table above. The results are given in the 'Calculation of Ny,i,j' tab of the ER sheet. The ER numbers have been revised accordingly—refer to the 'ER Calculation' tab of the ER sheet.”

“The program engaged stakeholders through newspaper ads, emails, and radio announcements before the LSC meeting on 1st March 2023. The meeting was held from 9:00 AM to 11:00 AM at Gorillas Golf Hotel, Nyautarama, Rwanda, ensuring gender- inclusive participation. Sessions included program presentations, cookstove demonstrations, and open discussions. Outcomes were documented through photos, videos, attendance records, written feedback and were shared with VVB for validation. Consultation outcome”
“1. Toll-Free Helpline – DelAgua provides a toll-free helpline for stakeholders to connect and seek assistance. 2. Community Health Worker (CHW) Network – The CHW network collects feedback directly from end users and local authorities. This method is widely used as many rural Rwandans lack phone access. 3. Written Submissions via Local Government Offices – During stove distribution, end users are informed that they can submit written feedback to the nearest cell office, where it will be relayed to DelAgua through government officials. These mechanisms ensure that grievances are received, documented, and addressed in a structured and transparent manner. 2.1.5 Public Comments Comments received Actions taken There were no comments received during public comment period from 17 March 2023 to 16 April 2023 on VERRA website.”
“The ICSs decreases the GHG emission levels attributed to improved performance and design of the project ICSs. It does not involve change in baseline fuel or any other major interventions that negatively impacts biodiversity or ecosystems. Thus, the project does not affect or alter any largely intact or High Conservation Value (HCV) ecosystems, critical habitats, landscapes, key biodiversity areas or sites identified. Soil degradation and soil erosion”
“Prior to commencing the project, DelAgua signed a Memorandum of Understanding with Ministry of Environment to distribute improved cookstoves to rural households across Rwanda. Following this, DelAgua has signed Collaboration Agreements with the districts that the project has been delivered in (to date.) These agreements help the population in protecting the environment by scaling down firewood consumption while reducing indoor air pollution leading to improved respiratory health. Prior to distribution all potential ICS recipients are gathered to introduce the project. They are invited to receive a ICS free of charge. All recipients must consent to receive an ICS by attending a distribution day and signing the agreement on the bottom of the DelAgua poster. Outcome of FPIC The FPIC process ensured that all stakeholders were fully informed before establishing a transparent agreement. Beneficiaries voluntarily agreed to transfer carbon credit ownership at the time of ICS distribution. The project did not encroach on land, relocate people, or cause physical or economic displacement. Instead, it provides ICS for clean cooking, creates job opportunities, and improves health and environmental outcomes. The Project Proponent (PP) retains full and uncontested rights to the carbon credits generated from the use of project ICS.”
