We solved the routing problem so you don't have to

Accurate emissions require accurate distances. TerraTwin's engine automatically calculates real-world routes for road, sea, air, and rail—handling port constraints, airport runway constraints, and flight paths.

Automated Routing

Don't just draw straight lines. We route trucks on roads, ships in shipping lanes, and planes on great circle paths.

Standards Built-in

ISO 14083, GLEC, and EN 16258 logic is baked into the API. You never need to update emission factor tables again.

Address Geocoding

Send us street names, ports, airports, or raw addresses and we'll resolve them. Send geo coordinates if you have exact locations.

99.9% Uptime

Built on scalable cloud infrastructure to handle millions of requests per day for enterprise workloads.

Ship features, not research papers.

Building an accredited carbon calculation engine from scratch takes months of research, certifications, and data sourcing. With TerraTwin, it takes an afternoon.
