Carbon accounting that survives an auditor
Karbon0 automates Scope 1, 2 and 3 emissions accounting and produces reports aligned to GRI, TCFD and the ISSB standards — with an audit trail from every disclosed number back to the invoice it came from.

The problem
The calculation is easy. The evidence is not
Singapore's climate reporting regime does not just ask for a number. It asks you to stand behind it, and eventually to have it assured.
Scope 1 and 2 greenhouse gas reporting is already mandatory for Singapore-listed issuers, with wider obligations phasing in over the following years and external limited assurance arriving later still. ACRA and SGX RegCo extended several of these timelines in 2025, which bought companies time — it did not remove the requirement.
The hard part is never the arithmetic. It is collecting defensible activity data from operations and suppliers, applying the right emission factor for the right year and geography, and being able to show six months later where a figure came from. Spreadsheets do the first calculation adequately and the second reporting cycle terribly.
Worth knowing: Singapore has taken an ISSB-informed, climate-first approach rather than adopting IFRS S1 and S2 wholesale into law. Karbon0 maps your data to the ISSB-based disclosures embedded in the SGX rules, and to GRI and TCFD where you also report against those.

Capabilities
What Karbon0 does
Built around the reporting cycle rather than a dashboard, because the deadline is what actually creates work.
Activity data capture
Utility bills, fuel records, travel bookings, refrigerant logs and production data, imported from file, API or manual entry with validation rules.
Calculation engine
Versioned emission factor sets, unit conversion, location and market-based electricity accounting, and recalculation of prior periods when factors are restated.
Supplier engagement
A portal for suppliers to submit their own data, with request tracking, reminders and a completeness view across your value chain.
Assurance readiness
Every figure traceable to a source document, change history on every input, and reviewer sign-off before a period is locked.
Reporting
GRI, TCFD and ISSB-aligned outputs, plus your own board pack formats, exportable to Word, Excel and PDF.
Targets & pathways
Baseline setting, target tracking against SBTi-style trajectories, and scenario modelling for planned reduction initiatives.
Who it's for
For the person who signs the report
Large private groups
Businesses preparing for obligations that phase in later, or responding to customer and lender questionnaires now.
Emissions-heavy operations
Logistics, manufacturing and facilities operators where Scope 1 is material and reduction has a real cost attached.
Karbon0 FAQ
Before you get in touch
Yes, including the supplier data collection that makes Scope 3 workable. Categories are configured to your value chain rather than all fifteen by default, because reporting a category badly is worse than documenting why it is not material.
GRI, TCFD, and the ISSB-based climate disclosures as embedded in the SGX Listing Rules. Singapore has not adopted IFRS S1 and S2 directly into law, so we map to what the rules actually require.
External limited assurance on Scope 1 and 2 has been deferred under the revised Singapore timelines, but the system is built for it: source documents attached to every figure, change history, and period locking with reviewer sign-off.
Yes, if you run ITMOS or another telematics system we can integrate. Fuel consumption becomes a Scope 1 input without anyone re-keying it.
Not at all — consultants are often the ones who ask us to deploy it, because it removes the spreadsheet handling from their engagement and leaves them on the advisory work.
