Claim: 43% of CO2 from commercial aviation was linked to passenger movement in narrowbody aircraft, followed by widebody jets (33%), and regional aircraft (5%).

Passage: At the end of July 2015, the top 50 aircraft lessors managed 8,184 aircraft: 511 turboprop regional airliners, 792 regional jets, 5,612 narrowbody and 1,253 widebody airliners.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Narrowbody are dominant with 16,235, followed by 5,581 Widebodies, 3,743 Turboprops, 3,565 Regional jets and 399 Others.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In 2018, global commercial operations emitted 918 million tonnes (Mt) of CO₂, 2.4% of all CO₂ emissions: 747 Mt for passenger transport and 171 Mt for freight operations.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Today, turboprop aircraft – probably in part because of their lower cruising speeds and altitudes (similar to the earlier piston-powered airliners) compared to jet airliners – play an obvious role in the overall fuel efficiency of major airlines that have regional carrier subsidiaries.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A wide-body aircraft, also known as a twin-aisle aircraft, is a jet airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Berger predicts a 24% CO2 share for aviation by 2050 if fuel efficiency improves by 1% per year and if there are no electric or hybrid aircraft, dropping to 3–6% if 10-year-old aircraft are replaced by electric or hybrid aircraft due to regulatory constraints, starting in 2030, to reach 70% of the 2050 fleet.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The largest group being electricity production accounting for 37% of carbon emissions, followed by personal ground travel at 22%, natural gas not used towards power at 11%, movement of goods by boat, truck, or air at 9%, oil refining at 6%, other uses of petroleum at 6%, jet fuel, specifically for air travel, at 4%, and the last 5% spread among other miscellaneous uses.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Due to projected growth in air travel, in the most technologically radical scenarios for having a better than 50 % chance of keeping global warming below 2 degrees Celsius, in 2050 aviation will make up 15 % of global CO2 emissions.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In Europe, the average airline fuel consumption per passenger in 2017 was 3.4 L/100 km (69 mpg‑US), 24% less than in 2005, but as the traffic grew by 60% to 1,643 billion passenger kilometres, CO₂ emissions were up by 16% to 163 million tonnes for 99.8 g/km CO₂ per passenger.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A 2014 life-cycle assessment of the cradle-to-grave reduction in CO by a carbon-fiber-reinforced polymer (CFRP) airliner such as a Boeing 787—including its manufacture, operations and eventual disposal—has shown that by 2050 such aircraft could reduce the airline industry's CO emissions by 14–15 percent, compared use of conventional airliners.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Due to projected growth in air travel, in the most technologically radical scenarios for having a better than 50% chance of keeping global warming below 2 degrees Celsius, in 2050 aviation will make up 15% of global CO emissions.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Like the majority of human activities involving combustion, most forms of aviation release carbon dioxide (CO) and other greenhouse gases into the Earth's atmosphere, contributing to the acceleration of global warming and (in the case of CO) ocean acidification.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In addition to the CO released by most aircraft in flight through the burning of fuels such as Jet-A (turbine aircraft) or Avgas (piston aircraft), the aviation industry contributes greenhouse gas emissions from ground airport vehicles and those used by passengers and staff to access airports, as well as through emissions generated by the production of energy used in airport buildings, the manufacture of aircraft and the construction of airport infrastructure.
