Carbon Tracker

Overview

The Carbon Tracker calculates CO2 emissions for every flight you take, using the same methodology that governments and airlines use. You get per-trip numbers, cumulative totals, and a clear picture of your travel footprint over time.

How the Math Works

MileIntel uses ICAO and DEFRA calculation standards. The formula accounts for:

• Great-circle distance — Haversine calculation between origin and destination, plus a detour factor for non-direct routing.
• Cabin class multiplier — Economy uses a 1x factor. Premium economy is ~1.5x. Business is ~2.5x. First class is ~3x. This reflects the physical space each seat occupies.
• Aircraft type adjustments — Newer aircraft (787, A350) produce less CO2 per kilometer than older models.
• Load factor — Average passenger load for the route and airline.

What You See

Each trip shows its carbon output in kilograms of CO2. Your dashboard displays a running total for the current year, a comparison to previous years, and where you fall relative to average traveler benchmarks.

Key Details

• Navigator sees per-trip calculations. Executive and Black get cumulative tracking with goals and year-over-year trends.
• Emissions calculate automatically when flights are added to trips.
• Numbers update if you change cabin class or routing.

Tips

1. Use the tracker to compare routing options — a nonstop in economy often beats a connection in business on emissions.
2. Check your yearly total before purchasing carbon offsets so you buy the right amount.
