Quick answer: DEL → TAS carbon at a glance
Flying DEL to TAS (982 mi) emits about 88 kg CO₂ per passenger in economy (incl. radiative forcing). Train is ~35 kg, 4-person carpool ~99 kg, solo car ~397 kg. The greenest option here is train at 35 kg — about 60% less than flying.
Factors: 0.09 kg/mile flight, 0.0355 train, 0.404 solo car (DEFRA/EPA).
Flying from New Delhi (DEL, India) to Tashkent (TAS, Uzbekistan) — a medium-haul regional covering 982 miles (1,580 km) — emits approximately 88 kg of CO₂ per passenger in economy class. This estimate uses the factor 0.09 kg CO₂ per passenger-mile (kilometre equivalent: 0.056 kg/km), which incorporates radiative forcing — the warming effect of non-CO₂ emissions (water vapour, nitrogen oxides, soot) released at cruise altitude. Excluding radiative forcing, the pure CO₂ alone would be roughly half this number. For context: the average US resident emits about 16 tons (16,000 kg) of CO₂ per year from all activities, so this one flight equals about 1% of an American's annual carbon budget. The route's carbon intensity is moderate per mile — see the comparison table below for alternative-mode emissions on the same route.
On the same 982-mile route, the lowest-carbon alternative is Train at ~35 kg CO₂ per passenger — about 60% less than flying. By contrast, a solo driver in a typical 22-mpg car would emit 397 kg over the same distance (about 351% more than the flight — solo driving is usually worse than flying on long routes because the car's per-vehicle emissions aren't shared across passengers). A four-person carpool drops the per-passenger footprint to 99 kg. To neutralise the climate impact of this flight, you'd need to plant about 5 tree-years (i.e. one mature tree absorbing CO₂ for 5 years, since a mature tree sequesters ~21 kg CO₂ per year according to the US EPA). That's also equivalent to about 20,000 smartphone charges on the US grid, or about 218 miles of solo driving in a typical car. The route's overall difficulty score (a separate metric combining distance and time-zone change) is 3/10.
Bars are scaled relative to the flight's per-passenger emissions (88 kg). All factors assume one passenger per seat for flight, one passenger for the solo car, four passengers sharing the carpool vehicle, and one passenger on a long-distance train. Air-rail comparison only valid where direct rail service exists on this corridor; actual rail distance may be longer than the great-circle flight path.
How this carbon footprint is calculated
TripRoute multiplies the great-circle distance between DEL and TAS (982 miles) by 0.09 kg CO₂ per passenger-mile to estimate the per-passenger climate impact of an economy flight. This factor is based on the UK Department for Business, Energy & Industrial Strategy (BEIS/DEFRA) greenhouse-gas conversion factors for short-haul economy air travel, scaled up to include radiative forcing — the non-CO₂ warming effects (water-vapour contrails, nitrogen oxides, soot) that approximately double the climate impact of emissions released at cruise altitude. For the train comparison we use the European long-distance rail average of 0.0355 kg CO₂ per passenger-mile (≈ 0.022 kg per passenger-km), which is lower than flying because electric trains draw from grid power that is increasingly decarbonised. The car factors come from the US EPA's typical light-duty vehicle emissions of about 8.89 kg CO₂ per gallon of gasoline, divided by a real-world average of 22 miles per gallon → 0.404 kg CO₂ per mile per vehicle; a four-person carpool divides this by four. Tree-offset and equivalent-driving conversions use the US EPA estimate that one mature tree sequesters about 21 kg of CO₂ per year. All factors are publicly published industry-standard numbers — no fabricated data.
TRIs offsetting DEL → TAS worth it?
At 88 kg of CO₂ per passenger this is a moderate-impact flight; one high-quality offset corresponds to roughly 5 tree-years. Taking a direct flight matters more than offset brand — a connection can roughly double emissions.

New Delhi to Tashkent — quick answers
What is the carbon footprint of flying from New Delhi to Tashkent?
Flying DEL (New Delhi) to TAS (Tashkent) — 982 miles (1,580 km) — emits about 88 kg of CO₂ per passenger in economy class. This includes radiative forcing from non-CO₂ emissions at altitude, which roughly doubles the climate impact compared to the CO₂ alone.
Is it greener to take the train or drive from New Delhi to Tashkent?
On this 982-mile route: train ≈ 35 kg CO₂ per passenger, 4-person carpool ≈ 99 kg, flight ≈ 88 kg, and solo car ≈ 397 kg per passenger. The lowest-CO₂ option is train at 35 kg, roughly 60% less than flying.
