Air travel is an essential part of the professional lives of many academics, and a major source of pollution from that sector. In the context of the climate crisis, there have been appeals to reduce air travel by replacing it with other modes of transportation, replacing it with videoconferencing, or renouncing inessential trips.

Role of air travel in academia

The individual emissions of academic researchers are high compared to other professionals, "primarily as a result of emissions from flying to conferences, project meetings, and fieldwork".[1][2] Beyond their usefulness for doing research, these travels are motivated by career incentives, as decisions to award faculty positions or research funding depend in part on the applicants' activity as speakers at international conferences. Touristic opportunities also contribute to motivating these travels, which are considered as a perk of the profession.[1] the While conferences and meetings are important for exchanging ideas and nurturing professional relationships, this can also be done using alternative modes of communication such as videoconferencing and social media. It has been argued that the benefits of face-to-face meetings might be outweighed by the benefits of the alternatives, such as reaching wider communities.[1]

Attitudes of academics and their institutions

A 2014 study of three New Zealand universities found that rhetoric on sustainability coexisted with assumptions about the necessity to travel, and policies that encouraged travel.[3]

Emissions and their reduction

Estimated emissions

The CO2 emissions for a single conference trip were estimated to 7% of an average individual’s total CO2 emissions. The total emissions of scientists travelling to conferences for presenting papers were estimated to 0.228% of international aviation emissions in 2008.[4]

In a case study of a PhD project, mobility represented 75% of the carbon footprint, which could have been reduced by 44% using videoconferencing. The total emissions were 21.5t CO2-eq or 2.69t CO2-eq per peer-reviewed paper.[5] (In comparison, the carbon footprint of computers, printers, etc is estimated to only 5.44kg CO2-eq per paper.[6])

Estimated possible reductions

Optimizing the locations of the conferences of the International Biogeography Society could reduce emissions by about 20%, according to a 2014 study.[7]

Activism

Consequences of scientists' emissions on their credibility

Important motivations for scientists to fly less are to lead by example, and to be more credible when communicating to the public on climate change.[2] These motivations are particularly important in the case of climate scientists.

A 2016 survey has found that climate researchers' carbon footprints have a large effect on their credibility, and on participants' intentions to reduce their personal energy consumption.[8][9]

Voluntary reduction in air travel

Some academics reduce or stop flying in order to reduce their individual carbon footprints and/or to lead by example.

Meteorologist Eric Holthaus stopped flying in 2014, and claimed that slow travel made "his world shrink and become richer".[10]
