[carbonova api]

Climate intelligence embedded in your systems.

Calculation Endpoints

Emissions calculation (Scopes 1 to 3) via REST calls, with versioned, automatically updated emission factors mapped to the main regulatory frameworks.

Scenario Simulation

Simulate the impact of operational changes on your carbon footprint before implementing them, with low-latency responses.

Regulatory Reports

Automatic generation of CBAM, CSRD, ISSB and CORSIA reports via API, with an audit trail back to the source data.

Native Integration

SDK for Python, Node.js, and Java. Webhooks for emission events and real-time compliance alerts.

Under the GHG Protocol Corporate Standard, changes in calculation methodology or more accurate emission factors that significantly affect base-year emissions require those emissions to be recalculated, so every calculation must keep the factor version it used.

REST

REST endpoints with OpenAPI 3.0 documentation for Scopes 1–3 calculation, simulation and regulatory reporting.

Regulatory frameworks supported natively: EU CBAM, CSRD, ISSB (IFRS S1/S2), AASB S2, CORSIA and the Safeguard Mechanism.

[our purpose]

Carbonova API is the programmatic interface of CarbonOS. It allows any external system — ERPs, supply chain platforms, supplier portals — to access emissions calculation, scenario simulation, and regulatory report generation with simple, secure REST calls.

What is Carbonova’s emissions calculation API?

It is the programmatic interface of CarbonOS, Carbonova’s platform of AI agents. Through REST calls, any system sends activity data, such as fuel or energy use or freight, and gets back Scope 1, 2 and 3 emissions calculated with versioned emission factors. The same API simulates scenarios before an operational change and produces CBAM, CSRD, ISSB and CORSIA reports, with an audit trail.

Who is Carbonova’s emissions API for, and what problems does it solve?

It is for IT, product and sustainability teams that need carbon calculations inside the systems they already run: ERP, logistics platforms, procurement and supplier portals. It solves three common problems: the same data calculated in different ways by different teams, spreadsheets that cannot keep up with transaction volumes, and emission factors swapped without a record, which makes a number impossible to explain in an audit.

How does Carbonova’s emissions calculation API work, and what data does it take?

You send activity data in a single call or in batch: litres of diesel, kWh, tonne-kilometres of freight or quantities of purchased material. AI suggests the right emission factor from a database of global factors, the API returns emissions calculated with versioned factors, and webhooks notify your systems of emission events and compliance alerts. Results can feed the CarbonOS inventory with full lineage.

Which standards and reports does Carbonova’s emissions API support?

Calculations follow the GHG Protocol Corporate and Scope 3 standards and ISO 14064, and results feed CBAM, CSRD, ISSB (IFRS S1 and S2) and CORSIA reports. Versioning answers a GHG Protocol rule: when a change in methodology or emission factors significantly affects base-year emissions, those emissions must be recalculated. Carbonova does not verify or certify inventories; it hands the verifier the audit trail.

How does Carbonova’s API connect with the rest of CarbonOS?

The API runs on the same calculation engine as Carbon Intelligence, the CarbonOS inventory agent. Signal Ingest handles connectors to ERP systems such as SAP and Oracle and to transport systems; Proof Engine keeps the lineage and version of every factor; Supply Chain organises Scope 3 supplier data; and Compliance Hub turns results into reports. The number calculated in your system is the same one in the inventory.

What happens to past calculations when an emission factor changes in Carbonova’s API?

Nothing is lost. Because factors are versioned, each calculation stays linked to the factor version used at the time, and Proof Engine keeps the change history. When a new factor is released, you can recalculate the period in batch and compare it with the previous result, which helps decide whether the change requires a base-year recalculation under your GHG Protocol policy. Published numbers stay explainable.
