raestimo produces ESG ratings to assess companies’ sustainability performance in the areas of environment, social issues, and governance. The goal is to provide a structured, transparent, and comparable assessment of a company’s ESG performance. The rating serves as an analytical and transparency tool and does not constitute an investment recommendation, legal advice, or a market value forecast.
Our rating approach is based on the analysis of ESG-related information and the application of a documented methodology to determine an ESG score and ESG rating. In this process, environmental, social, and governance-related factors are assessed and synthesized using a standardized procedure.
The ESG assessment is conducted using a structured model that takes both quantitative and qualitative ESG factors into account. This involves analyzing, among other things, company information, ESG metrics, and publicly available data sources. The information collected is processed in accordance with the raestimo methodology and aggregated into individual ratings for the Environment, Social, and Governance categories, as well as an overall result.
The assessment is based on a closed technical system that supports data analysis and model calculations. The methodology also takes into account geographic, cross-national, and industry-specific patterns and trends.
ESG ratings are based on various data sources. These include:
Company Information
Published Corporate Reports
Sustainability Reports
Publicly Available Data
Statistical data from European and international institutions
Other ESG-related sources of information
raestimo uses the NACE Rev. 2 statistical classification of economic activities published by Eurostat and the European Commission, respectively. If a different or updated version is used, this will be specified in the respective rating or fact sheet. The official documentation for the NACE classification used is available on the Eurostat website. In addition, publicly available company information and reports are automatically collected and analyzed.
raestimo uses the European Classification of Economic Activities (NACE Rev. 2) or the version specified in the respective rating for industry classification. It is published by Eurostat / the European Commission. Classification is generally performed at the most detailed level available, specifically NACE Level 4, provided that sufficiently reliable data is available. If a reliable classification at this level is not possible, an aggregated NACE level may be used.
The industry classification is used to form peer groups, apply sector-specific weightings, and ensure the comparability of ESG metrics, and is disclosed in the respective fact sheet, rating, and report.
The relevance of individual ESG issues to sustainability varies significantly across industries. Therefore, raestimo takes industry-specific risk profiles and different materiality factors into account when compiling ESG ratings.
The specific structure of the assessment framework may vary depending on the industry, company size, and business model. The goal is to provide as accurate a representation as possible of the ESG risks and opportunities facing the respective company.
ESG ratings are calculated based on a published methodology. The rating is determined regardless of the nature, scope, or duration of a business relationship. The goal is to provide an objective and transparent assessment of a company’s ESG performance.
The basic principles of credit rating include:
Independence
Transparency
Traceability
Reliable Information Sources
Timeliness of the information used
raestimo classifies data based on its source, recency, completeness, and reliability. Data may come, in particular, from company information provided directly by the company, published annual reports, audited reports, public statistics and registry data, benchmark data, as well as derived or estimated values.
Missing or incomplete data may be supplemented using documented estimation or benchmarking methods. Such values are taken into account based on their quality and relevance and do not replace the company’s original data. The scope, timeliness, and quality of the available data may influence the rating.
raestimo uses automated systems for data collection and processing. The final methodology, evaluation logic, and calculation of results are based on the published ESG rating methodology.
An ESG rating is based on the information available at the time of the assessment. The validity of a rating therefore depends on the scope, timeliness, and quality of the underlying data.
Raestimo’s ESG ratings represent expert assessments of a company’s sustainability performance. They are not guarantees of future performance and do not replace legal, financial, or regulatory reviews.
The raestimo ESG rating methodology currently in use is published on this website. The specific version of the methodology, the data as of the date of publication, and the rating-related parameters used are also disclosed in the respective public rating fact sheet.
Current Methodology: raestimo ESG Rating Methodology
Current version: v1.0.1
Last updated: July 24, 2026
Rating-specific model version: See the respective fact sheet.
The ESG rating methodology is reviewed at least once a year and as needed.
A review based on specific circumstances may be conducted, in particular, in the following cases:
significant changes in regulatory or scientific principles;
new or significantly improved data sources;
identified methodological weaknesses or systematic data deviations;
significant changes in sector or country risks;
changes to the rating structure, weightings, score thresholds, or peer group logic;
findings from quality assurance, complaints, or model validations.
Before a change is approved, an assessment is conducted to determine whether it could materially affect the comparability of existing ratings or the ratings of companies that have already been rated. If necessary, the affected ratings are recalculated, updated, or accompanied by an appropriate note.
A change is considered material, in particular, if it is likely to significantly alter the ESG score, the rating class, an E, S, or G sub-rating, or the comparability with previous results for a relevant number of assessed companies.
Significant changes will be published before they take effect. The publication will include, at a minimum, the new version number, the effective date, a summary of the change, and a description of the expected impact. Where appropriate, affected stakeholders may be consulted in advance.
raestimo offers ESG ratings under various business models.
Issuer-Pays / Company-Pays: The company being rated, or a third party commissioned by it, commissions the ESG rating. This model can be used in particular for individual ratings, public ratings, ESG reports, and ESG labels.
Subscriber-Pays / User-Pays: A professional or institutional user—specifically a bank, insurance company, asset manager, investor, platform operator, or other institutional client—commissions and pays for the ESG rating service. In this model, the company being rated is not necessarily the client or the paying customer.
Data, API, and Portfolio Usage: raestimo can provide ESG ratings, scores, KPI data, and monitoring information under license, data, API, portfolio, or integration models.
Compensation is not dependent on the rating result, score, or label result.
For commissioned ESG ratings, the rated company may provide information and supporting documentation through a structured data collection process. The information submitted is reviewed for its source, timeliness, completeness, and reliability, and is taken into account in accordance with the published methodology.
For unsolicited public ratings, raestimo may use publicly available information without prior involvement from the rated company. The company may report factual errors, outdated information, or provide additional supporting evidence through the designated contact or complaint channel.
The involvement of a rated company is limited to the provision and factual verification of information. The company has no influence on the methodology, weighting, score calculation, or rating decision. Differing assessments by the company do not automatically lead to a change in the rating.
If new or corrected information is deemed material and reliable, the rating may be reviewed and, if necessary, updated.
