Context
Hi! I’m Samir, a Supply Chain Engineer and Data Scientist based in Paris, and founder of LogiGreen Consulting.
I help companies monitor and reduce their environmental footprint by combining AI automation, carbon estimation APIs, and workflow automation.
This workflow is part of our sustainability reporting initiative, allowing businesses to track the CO₂ emissions of employee flights.

Who is this template for?
This workflow is designed for travel managers, sustainability teams, or finance teams who need to measure and report on emissions from business travel.
Let’s imagine your company receives a flight confirmation email:
The AI Agent reads the email and extracts structured data, such as flight dates, airport codes, and number of passengers.
Then, the Carbon Interface API is called to estimate CO₂ emissions, which are stored in a Google Sheet for sustainability reporting.
How does it work?
This workflow automates the end-to-end process of tracking flight emissions from email to CO₂ estimation:
- 📨 Gmail Trigger captures booking confirmations
- 🧠 AI Agent extracts structured data (airports, dates, flight numbers)
- ✈️ Each flight leg is processed individually
- 🌍 Carbon Interface API returns distance and carbon emissions
- 📄 A second Google Sheet node appends the emission data for reporting
Steps:
- 💌 Trigger on new flight confirmation email
- 🧠 Extract structured trip data using AI Agent (flights, airports, dates)
- 📑 Store flight metadata in Google Sheets
- 🧭 For each leg, call the Carbon Interface API
- 📥 Append distance, CO₂ in kg, and timestamp to the flight row
What do I need to get started?
You’ll need:
- A Gmail account receiving SAP Concur or travel confirmation emails
- A Google Sheet to record trip metadata and CO₂ emissions
- A free Carbon Interface API key
- Access to OpenAI for parsing the email via AI Agent
- A few sample flight confirmation emails to test
