Positioning

Not just a calculator. A governable integration layer.

Emission calculation becomes operationally useful when it can be integrated, repeated, audited and governed across systems and organizations.

API for system integration

Expose emission calculation through documented endpoints instead of manual web-only workflows.

Explore API

Provider-neutral connectors

Use a stable domain interface instead of coupling specialist applications directly to one provider-specific API.

View connector approach

Organization-aware rollout

Plan API keys, users, roles, sub-organizations, fair use and support as part of the operating model.

Our mission

Verifiable CO₂ calculation for public-sector systems and specialist software.

Integrate emission calculations through a stable API, keep provider choices transparent, and preserve repeatability over time.

Designed for administrative workflows

Public-sector processes need explainable infrastructure, not black-box outputs.

CO₂ values used in professional or administrative settings should remain understandable over time. That means clear inputs, documented assumptions, versioned behavior, replayable responses and a realistic integration path into existing systems.

Replayability

Responses should contain enough information to document and understand how a result was calculated.

Time-stable models

Factors and calculation models should be date-aware so older results remain explainable.

Switchability

Connector-based integration reduces dependency on one provider-specific API format.

Governance

API keys, ownership, roles and organization structures should be manageable rather than hidden in custom code.

Current focus

Flight emissions, APIs and connectors

The current development focus is airport-based flight emission calculation, API access, provider-neutral connector libraries and the management functions needed for institutional use.

  • Flight calculation endpoint and airport lookup
  • API-key based access
  • Connector proof of concept
  • Pilot, organization and framework deployment models
Target audiences

Built for the people who have to make integration work

The product story is intentionally broader than an API endpoint: it addresses technical integration, procurement, governance and long-term maintainability.

Public-sector decision-makers

Evaluate CO₂ calculation as infrastructure with auditability, governance and procurement fit.

Compare packages

Internal IT teams

Integrate calculation into existing systems while keeping ownership of architecture and operating model.

Review API scope

Software vendors

Use connector libraries to support multiple providers and migration scenarios more safely.

Explore connectors

Framework operators

Plan multi-organization rollout models with support, API keys, usage rules and governance structures.

Transparent beta and pilot phase

The right first step is usually evaluation, not blind production rollout.

calco2la.to is currently being developed towards reliable production use. The public pages describe the intended direction, current proof-of-concept state and recommended pilot path. For production use, API behavior, request volume, versioning, support and auditability requirements should be clarified explicitly.
