For Agents

Compute per-passenger CO2e flight emissions for a specific carrier, flight number, and date so an agent can surface sustainability data alongside fare options.

Quickstart

Get started with Travel Impact Model API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"compute flight emissions"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with Travel Impact Model API API.

Compute CO2e emissions per cabin class for a specific flight leg

Return the model version stamp so historical estimates remain reproducible

Score multiple flight options in a single batch request for itinerary comparison

Surface per-passenger emissions to power sustainability badges in booking flows

View OpenAPI Document

The Travel Impact Model API returns carbon dioxide equivalent (CO2e) emission estimates for individual flight legs based on Google's Travel Impact Model. Given an origin airport, destination airport, operating carrier, flight number, and departure date, the API returns per-passenger emissions broken out by cabin class along with the model version used. It is designed for travel platforms, sustainability dashboards, and reporting systems that need consistent, comparable flight emissions data.

Use Cases

Patterns agents use Travel Impact Model API API for, with concrete tasks.

★ Sustainability Badges in Flight Search

Online travel agencies and metasearch engines display per-flight CO2e estimates next to fare cards so travelers can factor sustainability into booking decisions. The Travel Impact Model API returns emissions per cabin class for each carrier, flight number, and date combination, letting the front end render a green-leaf indicator or a numeric kilogram value. Integration is typically a single POST per fare list, and the model version is captured for audit consistency.

Call computeFlightEmissions for AA100 JFK to LAX on 2026-07-15 and return economy CO2e in kilograms

Corporate Travel Carbon Reporting

Corporate travel managers reconcile booked itineraries against an emissions model to produce quarterly Scope 3 disclosures. By passing each leg through the Travel Impact Model API, finance and ESG teams obtain comparable numbers across carriers and routes without maintaining their own emissions model. The model_version field stamped on every response keeps historical reports reproducible even after Google updates the underlying methodology.

Iterate over 412 Q3 booked legs and accumulate total economy-class CO2e per traveler

Carbon-Aware Travel Policy Enforcement

Travel platforms enforce internal sustainability policies by ranking eligible flights by emissions before applying price filters. The API returns a single emissions object per leg with a deterministic model version, enabling the policy engine to apply consistent thresholds (for example, exclude options more than 20 percent above the lowest-emission candidate). The single endpoint design keeps integration time low and avoids the need to mirror Google's underlying datasets.

Score five candidate flights and recommend the option with the lowest economy-class CO2e

AI Agent Sustainability Assistant

An AI travel assistant integrated through Jentic discovers the Travel Impact Model API by intent search, loads the request schema, and submits a flight emissions request as part of a conversational booking flow. Because the API has a single operation and a small input schema, it is well-suited to function-calling workflows where the agent must combine fare data, emissions data, and traveler preferences into one recommendation. Jentic isolates the Google API key in its vault so the agent never receives the raw credential.

Search Jentic for compute flight emissions, load the schema, and call it for the user's selected itinerary

POST

/v1/flights:computeFlightEmissions

Compute CO2e emissions for one or more flight legs

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Travel Impact Model API keys are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — the raw Google API key never enters the agent's context.

Intent-based discovery

Agents search Jentic for natural-language intents like 'compute flight emissions' and Jentic returns the computeFlightEmissions operation with its full input schema, so the agent can call the right endpoint without browsing Google's discovery doc.

Time to first call

Direct Travel Impact Model integration: 1-2 days for API key provisioning, schema mapping, and quota handling. Through Jentic: under 30 minutes — search, load schema, execute.

Choose Translation when a travel agent needs to render emissions copy or booking confirmations in the traveler's language.

Complementary

Cloud Monitoring API

Track call volume and error rates for the Travel Impact Model integration

Choose Monitoring when an operator needs alerting on emissions API latency or quota exhaustion in production.

Complementary

Cloud Dataflow API

Batch-score historical itineraries to produce ESG reports at scale

Choose Dataflow when a finance team needs to backfill emissions across millions of past bookings rather than score one itinerary at a time.

FAQs

Specific to using Travel Impact Model API API through Jentic.

What authentication does the Travel Impact Model API use?

The Travel Impact Model API uses a Google API key passed as the api_key query parameter on the single POST endpoint. Through Jentic, the API key is stored encrypted in the MAXsystem vault and only a scoped reference is exposed to the agent at execution time.

Can I compute emissions for multiple flights in one request with the Travel Impact Model API?

Yes. The /v1/flights:computeFlightEmissions endpoint accepts a flights array, so a single request can score an entire itinerary or candidate fare list and return one emissions object per leg with the model version stamp.

What are the rate limits for the Travel Impact Model API?

Google enforces standard Cloud project quotas on the Travel Impact Model API, defaulting to 60 requests per minute per project. Higher quotas can be requested in the Google Cloud Console; check the Travel Partner documentation for the current default for your project.

How do I get flight emissions through Jentic for the Travel Impact Model API?

Install the Jentic SDK with pip install jentic, search for compute flight emissions, load the schema for the computeFlightEmissions operation, then execute it with origin, destination, operating carrier code, flight number, and departure date. Jentic returns the same emissions and model_version response that the raw API does.

Is the Travel Impact Model API free to use?

Google currently offers the Travel Impact Model API at no cost for travel partners and developers, subject to project quotas and acceptable use terms. Confirm current pricing in the Google Cloud Console before high-volume rollout.

Why might the Travel Impact Model API return no emissions for a flight?

If the operating carrier, flight number, or route is not present in Google's underlying schedule and aircraft data, the API returns an empty emissions object for that leg. Verify the IATA airport codes, two-letter carrier code, and that the flight number exists for the requested departure date.
