ESG Book

ESG Book is a sustainability-data and technology provider for reporting, financing, risk management, and supply-chain decarbonization. Its platform combines public-company disclosures with information collected from private companies and maps those records to sustainability and regulatory frameworks.^[1] The principal products are Access, Engage, and Pulse.^[1]

Access is the company's public sustainability dataset, Engage supports direct collection of private-company or customer information, and Pulse monitors sustainability regulation across jurisdictions.^[1] ESG Book and EthiFinance announced a combination in 2025 to create a European group spanning sustainability data, ESG ratings, credit ratings, and risk modelling.^[3] Crunchbase independently profiles ESG Book as a sustainability-data business.^[4]

What It Does

ESG Book centralizes environmental, social, governance, climate, and emissions fields for companies and portfolios. Financial institutions can use the records in sustainability disclosures, underwriting, borrower monitoring, and transition-finance processes. Corporate users can request data from suppliers, identify gaps, and calculate or document Scope 1, Scope 2, and Scope 3 emissions with company-supplied evidence where available.^[1]

Data And Methodology

The company states that it links data points to source documentation and applies automated checks, input validation, and sample testing.^[1] Access exposes publicly available company climate and sustainability records, while Engage collects information from private counterparties through standardized requests and maps responses to selected frameworks.^[2] A validated record is not necessarily audited: users must distinguish reported values, calculated fields, estimates, and validation rules and should review the applicable methodology before relying on cross-company comparisons.

Products And Delivery

Access provides the public-company dataset and associated source documents. Engage manages outreach, data entry, validation, and framework mapping for information that is not readily available in public filings. Pulse tracks regulatory developments and alerts users to relevant obligations across more than 100 jurisdictions, according to the company.^[1] ESG Book describes scalable pricing but does not display a universal public tariff; prospective customers are directed to sales.^[1]

Buyers And Use Cases

Banks can incorporate emissions and sustainability indicators into lending, target setting, and customer reporting. Corporations can collect supplier data and monitor decarbonization programs, while governance and risk organizations can embed selected fields in research or screening workflows.^[1] ESG Book publishes case studies involving Glass Lewis, Interos, and other organizations, but these vendor-selected examples should be interpreted as illustrations rather than independent performance evaluations.^[2]

Corporate Development And Limitations

EthiFinance's announcement describes the combined group as joining its credit and sustainability-rating capabilities with ESG Book's global data and technology platform.^[3] This broadens the corporate group beyond data collection, but the products, legal entities, and methodologies should not be assumed to have become identical. More generally, sustainability reporting remains affected by incomplete disclosure, changing legal definitions, organizational-boundary choices, and estimation of value-chain emissions. Platform coverage and automated checks reduce processing work but do not remove those underlying uncertainties.
