What we build
A GHG ledger engineered for assurance — not a spreadsheet.
Each capability is a production component — wired into your stack, documented for your assurance provider, and ready for the next restatement the moment a factor updates.
Scope 1, 2, and 3 data ingest
ERP, utility APIs, fleet fuel cards, supplier-spend exports, grid factors, and surveys — pulled on a cadence, normalised into a single schema, and tagged with source and period.
GHG ledger with full lineage
Every tonne of CO2e traces back to a source record — invoice, meter reading, fuel-card line. Records are hashed so nothing can be silently edited, and every change is versioned.
Emissions-factor library, versioned
IEA grid factors, DEFRA, EPA, national grids, and bespoke supplier-specific factors. Every calculation carries the factor version it used, so restatements are a query, not a rebuild.
Automated data-quality checks
Variance, completeness, outlier, and unit-consistency checks run every ingest. Anomalies are flagged with evidence and routed to the plant owner before they reach disclosure.
Disclosure packs on every framework
ISSB IFRS S1/S2, TCFD, CSRD ESRS E1, SEC climate, SGX and Bursa sustainability. One ledger, multiple output formats, mapped line-by-line with a provenance note per metric.
Carbon-credit lifecycle
Registry look-ups, serial-number matching, retirement evidence, and double-counting checks across Verra VCS, Gold Standard, and national registries — avoidance vs removal tagged.
Who we build this for
One ledger, every disclosure obligation.
The same ledger powers a listed manufacturer preparing ISSB disclosure, a renewable-energy operator proving PPA-backed Scope 2, and a logistics group measuring its fleet. Boundaries, frameworks, and emissions factors change — the data infrastructure underneath stays consistent, versioned, and assurance-ready.
Group-level disclosure for listed manufacturers
Consolidated Scope 1/2/3 for Bursa, SGX, and SET-listed groups preparing IFRS S2 or CSRD-aligned reports. Plant-level ingest, group-level roll-up, segment reporting where required.
→ 14 plants · single ledgerRenewable-energy operators
PPA-backed clean-energy attribution, location- vs market-based Scope 2 splits, and retired REC/GO matching — so your green electricity claim survives assurance review.
→ market vs location logicC&I energy managers
Commercial and industrial portfolios with dozens of sites — chain-of-custody for RECs, PPA allocations, and behind-the-meter generation reconciled against utility bills.
→ per-site + portfolio viewLogistics and fleet Scope 1
Fleet fuel cards, telematics, and mobile combustion sources reconciled against fuel-card spend — with mode splits (road, rail, air, ocean) for downstream Scope 3 Cat 4 + 9.
→ fuel + distance methodsSupplier Scope 3 programmes
Supplier questionnaires, primary data collection, and spend-based gap-fill for Cat 1, 3, 4, and 11. Vendor portal, submission tracking, and data-quality scoring per supplier.
→ 3,000+ vendors at scaleBoard + regulator dashboards
Board-ready summary, regulator-style disclosure view, and operations-level plant dashboards — fed from the same ledger so nothing diverges between internal and external numbers.
→ one source · many viewsModels that power the ledger
Where AI helps — and where we keep it out of the way.
Calculation is deterministic — the GHG-P rulebook decides the arithmetic. Models help where human judgement is slow: classifying supplier spend, imputing gaps, spotting anomalies, and matching credits.
Tree-based classifier that maps supplier-spend GL lines to GHG Protocol Scope 3 categories and appropriate emissions factors. Trained on your coding, not a generic industry taxonomy.
For vendors without primary data, an LLM-assisted model selects the best spend-based factor — DEFRA, EXIOBASE, or regional — with a confidence score and methodology note per line.
Time-series anomaly detection across plants and periods, with unit-consistency checks and reasonableness rules. Flags anything that would fail a preparer's own first review.
Matches retired credits by serial number against Verra, Gold Standard, and national registries. Cross-checks vintage, project type, and removal-vs-avoidance classification.
Data feeding the ledger
Every source, every cadence — versioned.
Pulled on a schedule, normalised into a single schema, tagged with source, period, and emissions-factor version. What the preparer sees is what the assurance provider will see.
Lineage, not just totals
A total alone doesn't pass assurance. A trail does.
Every tonne of CO2e on the ledger traces back to a source record — an invoice, a meter reading, a fuel-card line, a supplier submission. Emissions factors carry a version tag. Adjustments carry dual-control evidence. What lands in the disclosure pack is exactly what your assurance provider can reconstruct from source.
- Source-document hash on every ledger line
- Emissions-factor version tagged per calculation
- Dual-control adjustments with audit log
- Aligned to GHG-P, ISO 14064, and ISAE 3410 assurance
Frameworks we align to
One ledger. Every framework that matters.
Why Axccelerate for carbon reporting
Not a reporting template.
A carbon ledger.
A template gives you a completed form. Our ledger gives you source-to-disclosure lineage, automated quality checks, supplier engagement, and restatement support — the infrastructure a real assurance review actually demands.
Pricing
Priced to the reporting boundary, not the emissions volume.
Carbon deployments are custom — we scope against your entity structure, frameworks in scope, and assurance level before quoting.
Glossary
The vocabulary behind every tCO2e.
A quick reference for the acronyms that show up in ESG and carbon reporting — the terms your sustainability team, assurance provider, and regulator will all use.
- GHG Protocol
- Greenhouse Gas Protocol
The most widely used corporate emissions-accounting standard. Defines organisational boundaries, Scopes 1/2/3, and the methodologies most other frameworks (ISSB, CSRD, SBTi) build on.
- Scope 1
- Direct emissions
Emissions from sources owned or controlled by the reporting entity — stationary combustion, mobile combustion, fugitive refrigerants, and process emissions.
- Scope 2
- Indirect energy · location vs market
Emissions from purchased electricity, steam, heat, or cooling. Reported two ways: location-based (grid average) and market-based (contractual instruments like RECs, PPAs, GOs).
- Scope 3
- Value-chain · 15 categories
Indirect emissions up- and downstream: purchased goods, capex, fuel-and-energy, upstream transport, waste, travel, commute, leased assets, use-of-product, end-of-life, investments, franchises.
- CO2e
- Carbon-dioxide equivalent
A common unit that expresses all greenhouse gases as the warming-equivalent mass of CO2, using Global Warming Potential (GWP) factors — typically GWP100 from IPCC AR5 or AR6.
- Emissions factor
- Activity × factor = emissions
A coefficient that converts an activity — kWh, litres of fuel, USD of spend — into tCO2e. Factors are jurisdictional, time-varying, and tagged to a version on every calculation.
- Materiality
- Financial vs impact
Financial materiality (ISSB) asks what affects enterprise value. Impact materiality (CSRD) also asks what effects the entity has on people and planet. Double materiality is both.
- ISSB
- International Sustainability Standards Board
The IFRS Foundation board that publishes IFRS S1 (general) and IFRS S2 (climate). Adopted or referenced by regulators in Singapore, UK, Australia, Malaysia, and others.
- TCFD
- Task Force on Climate-related Financial Disclosures
Four-pillar framework — governance, strategy, risk management, metrics and targets — that ISSB has largely absorbed. Still referenced directly in SGX, SEC, and other regimes.
- CSRD
- Corporate Sustainability Reporting Directive
EU directive requiring large companies (and non-EU companies with EU operations above thresholds) to report under ESRS, with double-materiality and mandatory limited assurance.
- ESRS
- European Sustainability Reporting Standards
The standards that operationalise CSRD. ESRS E1 covers climate change; it is the primary target for any entity building a CSRD-aligned carbon ledger.
- SBTi
- Science Based Targets initiative
Validates corporate emissions-reduction targets against pathways aligned to the Paris Agreement. Target boundary, base year, and Scope 3 coverage all have specific validation rules.
- Assurance
- Limited vs reasonable
Limited assurance (ISAE 3000/3410) expresses a lower level of confidence than reasonable assurance. Most first-time ISSB/CSRD reporters start with limited, moving to reasonable over time.
- Carbon credit
- Avoidance vs removal
One tonne of CO2e avoided or removed, issued by a registry (Verra, Gold Standard, national). Avoidance prevents emissions; removal draws them down. They are accounted for separately.
