ESG Book review
A free-access ESG data platform with portfolio analytics, emissions data and disclosure workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ESG Book brings company and portfolio sustainability information into a cloud-based data and disclosure platform for financial institutions, investors and corporates. Its strongest audience is investors and analysts who need ESG data for screening, research, or investment and risk models; corporates can also use its reporting workflows. Public platform access is free, while advanced features are offered commercially. The product is positioned for mid-market and enterprise organizations, and is available through web access and API.
The data layer spans company ESG scores and performance analytics, sustainability KPIs, and reported and estimated Scope 1, 2 and 3 emissions. Users can download raw ESG data, work with modules for emissions, green revenue and ESG metrics, and build bespoke monitoring dashboards. Portfolio screening gives investment teams a way to examine holdings, while framework mapping connects disclosures to SASB, GRI, TCFD, ISSB and EU Taxonomy. The breadth suits teams combining investment analysis with reporting needs, though organizations looking only for a focused carbon-accounting tool may find this data-platform orientation broader than necessary.
For delivery and collaboration, ESG Book supports push/pull APIs and connections through Snowflake, AWS, Google Cloud, SFTP and CSV. Disclosure requests, centralized reporting and auditable collaboration support information gathering, while AI-assisted workflows help collect and validate customer data. These capabilities make it relevant to teams working across data sources and disclosure processes. Advanced features are paid, but the published plans do not provide prices, so buyers should clarify commercial access before committing. Investors and analysts seeking ESG data access are the clearest fit; smaller teams wanting a simple standalone workflow should compare narrower options.
