Flight vs Train Carbon Calculator
Per-flight and annual CO₂e with cabin class and radiative forcing — rail comparison included.
Under 800 km, rail beats air by ~70–90% per passenger — the comparison row makes it explicit for your route. France banned flights where rail does it in 2.5 h; your travel policy can too.
Business class roughly triples your footprint because you occupy 3× the cabin area. The RF factor is honest accounting for contrails and NOx at altitude — most corporate standards (and SBTi guidance) now include it. One avoided long-haul round trip beats a year of office LED retrofits.
Screening-level estimate using published average emission factors. Audited disclosures (BRSR, GRI, CDP) require primary activity data and verified factors — confirm with your sustainability auditor.

Frequently asked questions
How much CO₂ does one flight emit per passenger?+
Economy medium-haul: ~90 g/km — Delhi–Mumbai one way ≈ 100 kg before radiative forcing, ~200 kg with the 1.9 RF uplift. One long-haul economy round trip (Delhi–London) ≈ 2+ tonnes — comparable to an average Indian's entire annual footprint.
Why does business class triple the footprint?+
Space accounting: a business seat occupies roughly 3× the cabin area of economy, so it carries 3× the share of the aircraft's fuel (multipliers: premium 1.6, business 2.9, first 4.0). Corporate travel policies that cap class below a flight-hours threshold are carbon policy in disguise.
What is the radiative forcing (RF) factor?+
Aviation warms beyond its CO₂ — contrails and NOx at altitude roughly double the climate impact. The common multiplier is 1.9 (DEFRA convention); strict CO₂-only accounting uses 1.0. Disclose which you used; serious standards now expect RF included.
When does the train beat the plane?+
Under ~800 km, rail emits 70–90% less per passenger and often competes on door-to-door time. France legislated the principle (no flights where rail does it in 2.5 h); travel policies can too. The rail row prices your specific route's switch.
