Aviation emissions – articles from the Conversation website
The Conversation website is a platform for academics and researchers to share their knowledge and scientific expertise and research in a readily accessible and readable format. A selection of articles on tackling aviation emissions and aviation climate impact are listed below from 2014. This includes possible solutions such as early electric aviation, High Speed Rail, Sustainable Aviation Fuels, frequent flyer levies and demand management, opposing airport expansions:
- April 3, 2023 – Capitalising on climate anxiety: what you need to know about ‘climate-washing’ Laura Schuijers, University of Sydney. While the ACCC, ASIC and a new senate inquiry begin to flush out greenwashing, we take a closer look at dodgy climate claims. Complaints and court cases are stacking up. Here’s what you need to know. The case of Etihad greenwashing covered.
- February 22, 2023 – The future of flight in a net-zero-carbon world: 9 scenarios, lots of sustainable aviation fuel
Candelaria Bergero, University of California, Irvine and Steve Davis, University of California, Irvine. Airlines are investing in sustainable biofuel startups and starting to uses alternative fuels, including cooking oil, ag waste and corn ethanol. But biofuels alone won’t be enough, research shows. - February 13, 2023 – Why restoring long-distance passenger rail makes sense in New Zealand – for people and the climate
Robert McLachlan, Massey University and Paul Callister, Te Herenga Waka — Victoria University of Wellington. As part of its target to cut emissions, New Zealand aims for a 20% reduction in driving by 2035, mainly through better urban planning and travel options. Why doesn’t the plan mention intercity rail? - January 31, 2023 – X-57: Nasa’s electric plane is preparing to fly – here’s how it advances emissions–free aviation
Hugh Hunt, University of Cambridge. Batteries could well be powering short-haul flights in the near future. - December 22, 2022 – Why electric vehicles won’t be enough to rein in transport emissions any time soon
Philip Laird, University of Wollongong. Converting to electric cars is going to take time. With transport being Australia’s fastest-growing source of emissions, action on all fronts – road, rail, sea and aviation – is needed. Although domestic flights were producing just 9% of all pre-COVID transport emissions in Australia, a 50% increase in aviation emissions from 2005 to 2019 demands government action to limit further growth. This will be a challenge given Australians’ reliance on flying between capital cities and to regional centres. - October 7, 2022 – Climate change: the fairest way to tax carbon is to make air travel more expensive – Milena Buchs, University of Leeds and Giulio Mattioli, Technical University of Dortmund. Carbon taxes targeting luxury emissions are more popular than those which make necessities more expensive.

- May 18, 2022 – Bucking the trend: Is there a future for ultra long-haul flights in a net zero carbon world?, Susanne Becken, Griffith University and Paresh Pant, Griffith University. Ultra long-haul flights make it possible to go Sydney to London non-stop. But does the world need them, given they are more polluting and less efficient?
- February 22, 2022 – Why universities are starting to re-evaluate their academics’ travel – Sal Lampkin, PhD, Massey University and Robert McLachlan, Massey University.
