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.

Automate carbon tracking for your business travel with AI-powered workflows in n8n!

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:

1. 💌 Trigger on new flight confirmation email
2. 🧠 Extract structured trip data using AI Agent (flights, airports, dates)
3. 📑 Store flight metadata in Google Sheets
4. 🧭 For each leg, call the Carbon Interface API
5. 📥 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

Next Steps

🗒️ Use the sticky notes in the n8n canvas to:

• Add your Gmail and Carbon Interface credentials
• Send a sample booking email to your inbox
• Verify that emissions and distances are correctly added to your sheet
