One auditable system from emissions data to filed disclosure
Carbonkindle replaces manual spreadsheet workflows with a structured calculation system built for the assurance standards CSRD imposes on enterprise climate disclosures.
CSRD disclosure requires calculation infrastructure most enterprises don't have
Chief Sustainability Officers and ESG teams at mid-to-large enterprises facing mandatory CSRD disclosure deadlines are confronting a structural data problem. Enterprise teams spend 60–80% of disclosure season manually extracting emissions data from spreadsheets, ERP exports, and supplier portals, then stitching it together for auditors.
This process is prone to version drift, calculation errors, and last-minute restatements that delay regulatory filings and expose companies to CSRD non-compliance risk. CSRD is not voluntary. The financial and reputational consequences of late or restated filings are real and escalating.
The enterprises most exposed are those in EU-regulated industries — manufacturing, chemicals, automotive supply chains, financial services — where Scope 3 categories represent 80–95% of total reported emissions but remain the hardest to source and verify.
A structured pipeline from source data to disclosure package
Carbonkindle connects your existing data sources, runs the GHG Protocol calculations with full lineage, and outputs audit-ready ESRS E1 disclosure packages.
Connect your data sources
ERP exports from SAP S/4HANA, Oracle Fusion Cloud, and NetSuite arrive via API or structured CSV. Utility and energy invoices feed in alongside supplier emission factors from ecoinvent or custom libraries. Existing spreadsheet workbooks migrate with data lineage preserved.
Calculate with full audit lineage
The calculation engine maps incoming activity data to the GHG Protocol taxonomy, applies peer-reviewed emission factors, propagates Scope 1–2–3 boundaries, and flags anomalies against prior periods. Every tonne of CO2e is linked to its source document, emission factor version, and calculation date. A pre-built CSRD ESRS E1 template auto-populates disclosures and marks gaps for human review.
Export audit-ready packages
The complete CSRD ESRS E1 disclosure package exports as PDF and machine-readable XBRL. A restatement-safe calculation workbook with full data lineage accompanies every package. The continuous monitoring dashboard provides live emission-intensity KPIs by business unit, updated as source data changes.
Six capabilities that make CSRD disclosure defensible
Each feature was designed around a specific failure point that causes CSRD restatements or auditor rejections.
CSRD ESRS E1 Auto-Disclosure
Carbonkindle ships with a continuously updated ESRS E1 template library aligned to EFRAG guidance. As emission data flows in, the system auto-populates mandatory disclosure fields, calculates percentage progress toward targets, and surfaces gap items that require narrative input.
Auditors receive a structured disclosure package in both human-readable PDF and machine-readable XBRL formats, reducing review cycles from weeks to days. The template library is updated with each EFRAG guidance revision so that your disclosure format remains compliant as the standard evolves.
Full Scope 3 Coverage
Scope 3 is the hardest and highest-risk portion of any CSRD filing. Carbonkindle combines direct supplier data collection via a self-service supplier portal, spend-based estimation using Exiobase coefficients, and hybrid activity-based modeling to cover all 15 GHG Protocol categories.
Confidence scores on each category make materiality assessments defensible. A supplier engagement workflow nudges key vendors toward primary data submission over time, progressively improving disclosure quality without adding headcount to the ESG team.
Calculation Audit Trail
Every tonne of CO2e appearing in your disclosure is linked to its origin: the raw activity figure, the emission factor applied, its version, and the calculation date. If a data source is revised post-filing, Carbonkindle generates a restatement impact report instantly — rather than six weeks of spreadsheet archaeology.
The audit trail exports in a format accepted by Big-4 sustainability assurance teams. When your auditors arrive, every number is traceable. When regulators ask questions, every figure has a documented source.
Purpose-built for mandatory CSRD filers
Carbonkindle is not a general sustainability platform. It is compliance infrastructure for a specific category of enterprise.
Built for
- Head of Sustainability or Chief Sustainability Officer at a European-headquartered enterprise or US multinational with EU operations
- Mid-market to large enterprise: 500–10,000 employees; revenue EUR 40M–2B
- Operating in at least one EU member state, subject to mandatory CSRD reporting starting FY2025 or FY2026
- ESG teams with structured data collection ambitions who need assurance-grade outputs
- Finance teams co-responsible for the accuracy and auditability of CSRD filings
Not designed for
- SMBs with voluntary-only reporting ambitions not subject to mandatory CSRD thresholds
- Pure-US companies with no EU nexus and no CSRD obligation
- Organizations not yet at the structured ESG data collection stage
- Companies seeking a general corporate sustainability or marketing platform
