A 2024 study published in Communications Earth & Environment revealed that carbon dioxide emissions from private jet travel surged to 15.6 million tonnes in 2023, a 46% increase compared to 2019. Despite serving only 256,000 individuals—approximately 0.003% of the global population—the industry contributes significantly to greenhouse gas ...
Though methane causes far more heat to be trapped than the same mass of carbon dioxide, less than half of the emitted CH 4 remains in the atmosphere after a decade. On average, carbon dioxide warms for much longer, assuming no change in rates of carbon sequestration.
For covering long distances, longer flights are a better investment of the high energy costs of take-off and landing than very short flights, yet by nature of their length inevitably use much more energy. CO 2 emissions from air travel range from 0.24 kg CO 2 per passenger mile (0.15 kg/km per passenger) for short flights down to 0.18 kg CO 2 ...
Over and over, we have been told that methane is a potent greenhouse gas, it contributes to global warming, and since ruminants (i.e., cattle) produce methane, they are destroying the world. I ...
Aviation is one of three sectors identified in a study where "demand-side options" can have a large effect in "reaching SDS levels". [12] According to a study, the attainment of the 1.5–2 °C global temperature goal necessitates substantial demand reductions in the critical sectors of aviation, shipping, road freight, and industry, should large-scale negative emissions not be realized.

The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
An aviation biofuel (also known as bio-jet fuel, [1] sustainable aviation fuel (SAF) or bio-aviation fuel (BAF) [2]) is a biofuel used to power aircraft. The International Air Transport Association (IATA) considers it a key element in reducing the environmental impact of aviation. [3] Aviation biofuel is used to decarbonize medium and long-haul ...
It will be quicker to reach net-zero emissions for CO 2 alone rather than CO 2 plus other greenhouse gases like methane, nitrous oxide and fluorinated gases. [22] The net-zero target date for non-CO 2 emissions is later partly because modellers assume that some of these emissions such as methane from farming are harder to phase out. [22]
