The COVID-19 pandemic profoundly disrupted global aviation networks, with long-haul connectivity particularly affected. This study assesses the evolving competitive positions of sixteen major hub airports in the Asia-Pacific region by analyzing their transfer-connectivity performance before and...

Sustainable aviation fuels (SAFs) are promising solutions for reducing carbon emissions in the aviation industry and achieving the 2050 net-zero target. Despite their environmental benefits, the adoption and deployment of SAFs remain significantly below expectations. This paper systematically...

The non-CO2 aviation emissions (mainly contrails) can, in total, be up to twice as damaging for climate as the CO2 emissions associated to the use of kerosene. As the warming effect of the non-CO2 emissions depends strongly on metereological conditions, it is difficult to attribute the non-CO2...

Residual waste is no longer just ‘trash’ in the UK – it is a strategic climate resource. This new OIES study shows why policymakers and industry leaders need to rethink where it goes. The paper compares two competing pathways: using waste in Energy-from-Waste plants with carbon capture...

The European travel sector is experiencing a transformation driven by increased climate awareness and policy measures aimed at reducing external costs such as emissions. This study examines how Swiss travelers respond to these developments, using a stated preference experiment including the...

Drop-in alternative liquid fuels—Renewable Diesel (RD) and Sustainable Aviation Fuel (SAF)—offer material near-term abatement for hard-to-electrify transport segments, such as Aviation and heavy-duty transport; their deployment depends on pathway-specific costs, hydrogen requirements, and...

The objective of providing European Climate Law-aligned pathways and the Key Performance Indicators (KPIs) underpinning them is to offer a reference that companies can draw on to prepare their transition plans. By addressing an intermediate level between companies and the EU's economy-wide...

The analysis presented in this review provides an overview of the activities carried out in 2024 by the European Union Aviation Safety Agency (EASA) in response to safety recommendations, as well as a comparison with historical data. This review also highlights a range of safety issues and...

Asia-Pacific region especially is a developing region for airlines regarding competition, industrial development, and national perspective, COVID-19 had a destructive and re-definitive impact on the total aviation systems of the region. This study aims to perform a comprehensive analysis of the...

Background: Air traffic control is a stressful job and vital to aviation safety. Although technological developments have been introduced to enhance and facilitate the tasks of air traffic control officers (ATCOs), ATCOs still experience high levels of job stress. This study explores the...

The US-China direct flights in mid-2023 were only 7 percent of those available in mid-2019. This quasi-experiment informs the debate on air transport de-carbonization. An estimated structural model shows that re-establishing the pre-pandemic direct connectivity could increase passengers by 387...

The primary motivation for this study is the recent growth and increased interest in artificial intelligence (AI). Despite the widespread recognition of its critical importance, a discernible scientific gap persists within the extant scholarly discourse, particularly concerning exhaustive...

This study explores the potential for producing sustainable aviation fuels (SAF) in four African countries: Ethiopia, Kenya, Nigeria, and South Africa. Rather than serving as a full feasibility analysis or detailed project proposal, it uses a techno-economic approach to showcase Africa's...
