Question 1

What is carbon reporting and what does a carbon accounting platform do?

Accepted Answer

Carbon reporting is the systematic process of measuring, documenting, and disclosing an organisation's greenhouse gas (GHG) emissions — covering direct emissions from owned sources (Scope 1), indirect emissions from purchased energy (Scope 2), and all other indirect value chain emissions (Scope 3). A carbon accounting platform automates the data collection, calculation, and documentation workflows that carbon reporting requires — replacing manual spreadsheet-based processes with structured, repeatable, and audit-ready systems. For organisations subject to CSRD, carbon reporting under ESRS E1 (Climate Change) is a mandatory annual disclosure requiring Scope 1, 2 and 3 GHG data consistent with financial statements. For SBTi-committed organisations, an accurate and verified Scope 1, 2 and 3 GHG inventory is the data foundation on which science-based targets are set and annual progress is tracked. Ledger2Carbon's carbon accounting platform builds this inventory from financial and operational source data — producing GHG results that are consistent with the numbers CFOs and auditors already review.

Question 2

How does Ledger2Carbon's carbon accounting platform accelerate scope reporting?

Accepted Answer

Ledger2Carbon's carbon accounting platform accelerates scope reporting through three mechanisms. First, automated data ingestion — the platform integrates directly with existing ERP, accounting, and operational systems to pull the activity data (fuel consumption, electricity purchases, fleet mileage, procurement spend, waste records) that GHG calculations require, eliminating the manual data collection that typically extends reporting timelines by weeks. Second, structured calculation workflows — emission sources are organised by Scope and category with methodology documentation, emission factor selection, and uncertainty assessment built into each workflow step, ensuring nothing is missed and the calculation can be reproduced and reviewed efficiently. Third, assurance-ready output packaging — the platform continuously maintains the evidence, assumptions, and source documentation linked to each GHG result, so that when the annual reporting deadline arrives, verification preparation is largely complete rather than requiring an intensive documentation sprint. For organisations starting from scratch, this means a first GHG inventory can be completed in weeks rather than months. For organisations with an existing inventory, the annual repeat cycle runs significantly faster each successive year.

Question 3

How does Ledger2Carbon ensure data accuracy in carbon accounting?

Accepted Answer

Ledger2Carbon ensures carbon accounting data accuracy through its finance-first architecture — GHG emissions are calculated from the same source transactions that financial auditors review, rather than from sustainability-specific data entry that introduces transcription errors and inconsistencies. For each emission source, the platform maintains: the activity data record with its origin system and collection date; the emission factor applied with its source database and publication date; the calculation methodology with its GHG Protocol or ISO 14064-1 basis; and the uncertainty assessment. Built-in completeness checks identify missing data and undocumented assumptions before the reporting period closes, when corrections are low-cost. This architecture means that carbon accounting data is inherently consistent with financial statements — which is precisely what CSRD, ISO 14064-3, and ISAE 3410 assurance providers require when assessing GHG data credibility.

Question 4

Which compliance frameworks does Ledger2Carbon's carbon accounting platform support?

Accepted Answer

Ledger2Carbon's carbon accounting platform is built to support all major GHG reporting and carbon accounting compliance frameworks simultaneously from a single inventory. For regulatory disclosure, it supports CSRD ESRS E1 (Climate Change) Scope 1, 2 and 3 GHG data requirements and the associated limited assurance documentation. For voluntary and mandatory GHG reporting standards, it supports the GHG Protocol Corporate Standard (Scope 1, 2 and 3), ISO 14064-1:2018 organisational GHG inventories, and CDP (Carbon Disclosure Project) questionnaire data requirements. For science-based targets, it produces the Scope 1, 2 and 3 GHG inventory data required for SBTi target validation and annual progress reporting. For investor-facing disclosures, it aligns with TCFD climate metrics and ISSB IFRS S2 climate-related GHG disclosure requirements. For supply chain reporting, it produces the Scope 3 Category 1 and Category 11 data that value chain partners request through procurement questionnaires and supplier engagement programmes.

Question 5

What does Ledger2Carbon's carbon accounting platform deliver as outputs?

Accepted Answer

Ledger2Carbon's carbon accounting platform delivers five categories of output. GHG inventory data — Scope 1 direct emissions by source, Scope 2 location-based and market-based emissions, and Scope 3 emissions by category — structured to GHG Protocol and ISO 14064-1 requirements with full emission factor provenance. Assurance-ready documentation packages — the complete evidence set that ISO 14064-3 verifiers and CSRD limited assurance providers require, including methodology documentation, activity data sources, emission factor records, uncertainty assessments, and organisational boundary decisions. Regulatory disclosure data — CSRD ESRS E1 climate disclosure data points, TCFD metrics, and ISSB IFRS S2 GHG figures, structured for direct insertion into sustainability statement drafts. SBTi submission data — the verified Scope 1, 2 and 3 GHG inventory in the format required for SBTi near-term and corporate net-zero target validation. Reduction tracking — year-on-year emissions comparisons against the base year inventory, tracking progress toward carbon reduction targets with the documentation needed for CSRD target progress disclosures.
