Don't let AI guess
your emissions.
Let AI use TerraTwin.
TerraTwin MCP connects ChatGPT, Claude, and Copilot directly to a real emissions engine — so your team gets AI speed without sacrificing the rigour your reporting requires.
Why AI alone can't be trusted
with your emissions
Generic AI can write a freight emissions report in seconds. That doesn't mean it should calculate one. Without a dedicated system behind it, you get answers that sound confident but carry real risk.
Assumptions you never approved
Language models fill gaps with plausible-sounding logic — not your methodology. Every user gets a different answer based on how they phrased the question.
Hard to defend in audits
Emissions figures that vary by team, by prompt, by day. When a regulator or customer asks where the number came from, prose can't substitute for a calculation trace.
Multimodal chains are complex
Road, rail, air, sea, hubs — and the combinations between them. General AI doesn't have structured transport logic. TerraTwin was built for exactly this.
Customer and compliance exposure
Using AI-generated emissions in customer reports or CSRD submissions without a governed engine behind them is a liability waiting to happen.
AI becomes the interface.
TerraTwin remains the engine.
TerraTwin MCP is the connection layer between your AI tools and TerraTwin's emissions calculation capabilities. Instead of asking a model to figure out emissions from scratch, it calls TerraTwin directly — retrieves structured, methodology-backed results — and uses language to explain, summarise, and act on them.
Works today with ChatGPT, Claude, and Microsoft Copilot — and across any MCP-compatible AI tool.

Get audit-ready numbers.
Your AI agent understands the question, calls the TerraTwin MCP server, and returns structured emissions data — all in a single turn.
Compare the carbon footprint of shipping 20 tonnes from Shanghai to Rotterdam by sea vs. air
What is the lowest-emission route for my weekly European road distribution network?
Generate a scope 3 emissions summary for my Q2 freight spend and format it as a CSV
Here's the comparison for 5 tonnes, Shanghai → Hamburg:
Sea freight emits 96% less CO₂. Calculated via ISO 14083 methodology.
From best guess
to governed execution
Side by side, the difference is clear. TerraTwin MCP gives AI a backbone your reporting can actually stand on.
| Capability | ❌ Prompt-only AI | ✅ TerraTwin MCP |
|---|---|---|
| Source of calculation | General model training | TerraTwin's emissions engine |
| Methodology | Invented on the fly | Consistent, structured, traceable |
| Output format | Prose that looks right | Structured data + plain language |
| Consistency across your team | Varies by prompt | Same engine, every time |
| Transport mode coverage | Approximate at best | Air, rail, road, sea, multimodal |
| Fit for audits & compliance | Risky | Designed for it |
Built for freight emissions.
Not general-purpose AI theater.
TerraTwin is purpose-built for freight carbon calculations — a dedicated system built from the ground up for the complexity of freight, not a general tool adapted for sustainability.
Purpose-built for freight
Designed specifically for freight forwarders, shippers, and logistics providers — not retrofitted from a general carbon tool.
GLEC & ISO 14083:2023 aligned
Methodology aligned with the GLEC Framework and ISO 14083:2023 for audit-ready, defensible emissions reporting.
Structured API outputs
Not generated prose — structured data from a real calculation engine that integrates into your existing workflows.
All core transport modes
Air, rail, road, water, weighted modes, and hub operations — including full multimodal transport chains.
CSRD & SBTi ready
Outputs designed to support CSRD disclosure requirements and Science Based Targets reporting frameworks.
Trusted by leading logistics brands
Used by freight forwarders, shippers, and logistics providers who need both usability and rigour at scale.

Common questions
What is TerraTwin MCP?
It's the connection layer that lets AI assistants use TerraTwin's emissions calculation engine instead of relying on the model's own reasoning. AI handles the conversation. TerraTwin handles the calculation.
Why not just ask ChatGPT or Claude directly?
You can — but a language model alone will generate an answer, not calculate one. Freight emissions require transport logic, consistent methodology, and structured outputs. TerraTwin MCP gives AI a governed engine behind every result.
Which AI tools does it work with?
Today: ChatGPT, Claude, and Microsoft Copilot. Any MCP-compatible tool can connect using the custom connector flow. More integrations are coming as the ecosystem expands.
What transport modes are supported?
TerraTwin covers air, rail, road, water, weighted modes, and hub operations — including full multimodal transport chains across global networks.
How do I authenticate?
Using a personal TerraTwin API key, generated from your account area under Manage API Keys. Service accounts for team-level access are planned for a future release.
What changes when OAuth launches?
Connection becomes one click — no manual URL entry or API key management. Your TerraTwin account handles authentication directly through the AI client's connector store.
