What the figures say
Embraer 175 ranks 25 of 25 types for seat-miles per gallon in 2025, at 44.9. The Boeing 737-800, the most common type in the table, flew 79.1, so a gallon on the Embraer 175 carried a seat 43% less far. Over 1,000 miles, one seat on this type accounts for about 217 kg of CO2 from the fuel burned.
US airlines burned 1,086 million gallons on the Embraer 175 in 2025, 5.8% of the fuel burned on all scheduled passenger flying, over 1,691 thousand airborne hours and 1,246 thousand departures. The average flight spent 1.4 hours in the air and burned 872 gallons.
Since 2014, when it was first flown in volume, the type's figure has fallen from 48.3 to 44.9 seat-miles per gallon (7.0%). Its best year was 2020, at 53.4. The average flight got shorter, from 1.5 to 1.4 hours in the air, which tends to raise fuel burn per seat-mile, because take-off and climb take a larger share of the fuel on a short flight.
Airlines get different results from the same aircraft. Mesa Airlines flew 50.5 seat-miles per gallon on it and Republic Airways 41.7, a gap of 21%. It isn't the seat count: Mesa Airlines put 74 seats on each flight and Republic Airways 75. Flight length differs too, at 1.5 hours in the air per flight for Mesa Airlines and 1.3 for Republic Airways, and longer flights burn less fuel per seat-mile, which helps Mesa Airlines. What's left comes from taxi and holding time, weight, engines, how each airline operates and how it allocates fuel to types when it reports, and the filings can't separate those.

How to read this. Fuel is what airlines issued to the type in 2025, as filed with the US Bureau of Transportation Statistics, counted only for the hours spent on scheduled passenger flights and divided by the hours in the air. It includes fuel burned taxiing and holding, so it's higher than the cruise figure in a manual. CO2 is 9.75 kg per gallon of jet fuel.
