Annual ESG report assembled by manually pulling data from dozens of spreadsheets, energy bills, and system exports -- with no evidence trail for the figures you publish?
External assurance provider asking for data lineage and calculation methodology that your current process cannot produce?
ESG Reporting Software
Custom ESG reporting platforms that collect sustainability data from operational systems, map it to GRI, SASB, TCFD, and CSRD disclosure requirements, and produce audit-ready reports. Replaces the annual spreadsheet scramble with a structured, evidence-backed reporting process.
ESG reporting is now subject to external assurance in many jurisdictions. The spreadsheet processes most organisations rely on cannot produce the data lineage and audit trail that assurance providers require. We build the reporting infrastructure that can.
ESG data collection from operational systems -- energy, water, waste, HR, and facilities
Framework mapping engine aligning your data to GRI, SASB, TCFD, and CSRD requirements
Disclosure document generation with full data lineage for each reported figure
Audit trail and evidence management for external assurance provider review
RaftLabs builds custom ESG reporting software that replaces manual spreadsheet-based sustainability reporting with a structured data collection and disclosure platform. The software collects ESG data from operational systems, maps it to GRI, SASB, TCFD, and CSRD disclosure requirements, and generates reports with full data lineage and audit trail. Most ESG reporting software projects deliver in 10--14 weeks at a fixed cost.

The spreadsheet-based ESG report does not survive external assurance
The annual ESG report assembled from spreadsheets has a structural problem: it cannot answer the question "show me the source data and calculation behind this figure" in the way a financial audit expects. Each figure in the report was assembled manually, from systems that don't log which version of the data was used, by people who may no longer work at the organisation. External assurance providers require data lineage. Regulators require methodology documentation. Institutional investors want year-on-year comparability that is defensible under scrutiny.
Custom ESG reporting software solves this at the data collection layer. Data flows from source systems into a structured store with version control, calculation documentation, and an audit trail that persists across reporting cycles. The report is generated from verified data, not assembled from memory.
What we build
ESG data collection from operational systems
Automated data pipelines from the systems where ESG data originates: energy management systems, building management systems (BMS), utility provider portals, fleet management platforms, HR information systems, and waste management services. Scheduled data pulls replace manual exports. Unit conversion and normalisation handle the variety of formats different source systems produce. Data collection coverage maps directly to the disclosure requirements of the frameworks you report to -- so you collect what you need and nothing more.
Framework mapping engine for GRI, SASB, TCFD, CSRD
A framework mapping layer that takes collected ESG data and applies the specific disclosure requirements of GRI Standards, SASB industry-specific standards, TCFD recommendations, and ESRS under CSRD. The mapping is maintained as configuration -- when framework requirements change (as CSRD is phased in), the mapping updates without rebuilding the data collection layer. Organisations reporting to multiple frameworks collect data once and generate disclosures for each framework from the same underlying data store.
Disclosure document generation
Structured disclosure outputs in the formats regulators and stakeholders require -- XBRL-tagged ESRS reports for CSRD compliance, GRI content index tables, TCFD recommendation responses, and CDP questionnaire exports. Each disclosure figure is linked to its source data and calculation methodology. Disclosure drafts generated from the verified data store and routed through an approval workflow before publication. Historical disclosures preserved with the data versions that produced them -- so prior-year figures are reproducible.
Audit trail and evidence management
A complete audit trail for every ESG data point: source system, extraction timestamp, transformation applied, approval record, and the calculation methodology used to produce each disclosed figure. Evidence file management for supporting documentation -- energy invoices, waste certificates, third-party verification reports -- linked to the data points they evidence. Assurance provider access with read-only views of the audit trail and evidence so your external review process does not require manual document assembly each year.
Materiality assessment workflow
Structured double materiality assessment workflows for CSRD compliance -- identifying which sustainability topics are financially material and which have material impacts on people and environment. Stakeholder input collection, materiality scoring, and board-level review workflow. Materiality matrix visualisation with the rationale for inclusion and exclusion of topics. The materiality assessment output drives which GRI disclosures and ESRS data points the reporting platform collects -- connecting the assessment to the data collection process rather than treating them as separate exercises.
Year-on-year performance tracking
ESG performance dashboards that track metrics against targets and prior-year baselines. Absolute figures and intensity metrics (per unit of revenue, per square metre, per employee) so performance is comparable when business activity changes. Restatement management for prior-year data corrections with audit trail for why figures changed. Trend visualisations with variance analysis -- when a metric moves significantly, the system flags it for review before the figure enters a published report. The longitudinal view that turns annual reporting into ongoing performance management.
Frequently asked questions
The Corporate Sustainability Reporting Directive (CSRD) is an EU regulation that requires large companies and listed SMEs to report detailed sustainability information under the European Sustainability Reporting Standards (ESRS). It applies to EU companies with more than 250 employees, net turnover above EUR 40 million, or balance sheet above EUR 20 million -- and to non-EU companies with significant EU operations. The first cohort (large listed companies) began reporting for financial year 2024. Subsequent cohorts phase in through 2026 and 2028. CSRD requires external assurance on the sustainability report, which is why the audit trail and data lineage requirements are materially higher than voluntary reporting.
Data quality is managed at collection, transformation, and disclosure stages. At collection: source system integrations include data validation rules that flag missing values, out-of-range figures, and anomalies against prior periods before data enters the system. At transformation: calculation methodology is documented and version-controlled so any change to emission factors or calculation approach is tracked. At disclosure: each figure in the report links to its source data and calculation record. External assurance providers access a read-only view of this evidence trail. The system is designed to answer the specific questions assurance providers ask rather than generating a report and hoping the questions don't come.
Yes. The data model supports a hierarchical organisational structure -- group, region, country, and entity level -- with separate data collection for each entity and consolidation rules that aggregate to group level. Subsidiaries with different operational profiles (different energy sources, different waste streams, different industry classifications) have separate collection configurations appropriate to their operations. Group-level disclosures are produced from consolidated data with the entity-level breakdowns available for drill-down. This is particularly important for CSRD, which requires entity-level information for material subsidiaries.
A focused ESG reporting software project covering one framework (GRI or CSRD), integration with two to four operational data sources, and disclosure document generation typically costs $25,000 to $70,000. A multi-framework platform with integrations across five or more data sources, CSRD ESRS mapping with XBRL tagging, materiality assessment workflow, and external assurance access typically costs $70,000 to $150,000. We scope the project and fix the cost before development starts based on your framework requirements, number of data sources, and organisational complexity.
