We use a model of international and domestic tourist numbers and flows to investigate the effect of various climate policy instruments implemented in Europe on arrivals and emissions for the countries concerned. We find that these schemes do not fulfil their desired effects. The introduction of aviation into the European Trading system results in a fall in the number of tourists travelling into the EU in favour of other destinations. It also causes a significant welfare loss with only a small reduction in emissions. The flight taxes in the Netherlands and the United Kingdom result in different substitution effects across destinations (depending on the zones being taxed) but both policies do have the same consequence of inducing welfare losses and also reducing visitor numbers to the countries. We find that when these policies are combined their effects are additive. Welfare impacts are robust to variations in the underlying assumptions and changes in the scope of the taxes examined have the expected effects.

"This book assesses the extent to which two specialized UN agencies- the International Maritime Organization (IMO) in London and the International Civil Aviation Organization (ICAO) in Montreal - have been able to regulate environmental pollution in the global commons. Since the Kyoto Protocol and its tasking of these two International Organisations (IOs) in 1997 to regulate greenhouse gas emissions from the fast-growing international shipping and aviation sectors, they have struggled with the assignment even as the external pressure has mounted for them to act. David Deese examines why these two UN agencies have largely failed to execute their critical missions to date and explores the most promising emerging and feasible routes to control and reduce these emissions by other means. Drawing on a range of sources including interviews with key actors in the IMO and ICAO, as well as from industry and national governments, Deese looks at the multifaceted politics that drive these IOs and considers how this has delayed and frustrated the execution of their assigned climate mitigation missions. He also explains how the limitations of the IMO and ICAO are likely to be found to a degree in other UN specialized agencies and examines how lessons learned here will be helpful in understanding the operations of other IOs. The book will be of great interest to students and scholars of global governance and international organisations, transport and environment and climate change. It will also be a useful resource for industry and non-profit experts and public officials working in shipping and aviation regulation"--

Aviation emissions account for about 2.5% of global carbon emissions, and by 2050, their share could rise to 22%. This review article explores how climate scholars view the role of structural (policy- or business-focused) or agentic (individual-focused) approaches in reducing these emissions. From a structuralist perspective, aviation emissions require policy changes because they reflect regulatory and business failures to address the climate crisis. By itself, individual actions will not significantly reduce emissions. Moreover, focusing on personal (agentic) action might allow governments and firms to disavow their role in the climate crisis. From an agentic perspective, aviation emissions reflect carbon-intensive lifestyles. Even within the existing policy structures, individuals can reduce the carbon footprint of their travel. At the same time, individuals can serve as influencers, voters, and social movement participants to pressure governments and businesses to develop low-emission air travel policies. Rather than viewing agency and structures as distinctly separate approaches, we suggest that they could co-evolve to create pathways to reduce aviation emissions. Policy initiatives can facilitate individual efforts to reduce air travel emissions, and individual action could shape policies structuring their choices.

There has been a continuously growing trend in international commercial air traffic, with the exception of COVID-19 crises; however, after the recovery, the trend is expected to even sharpen. The consequences of released emissions and by-products in the environment range from human health hazards, low air quality and global warming. This study is aimed to investigate the role of aviation emissions in global warming. For this purpose, data on different variables including global air traffic and growth rate, air traffic in different continents, total global CO(2) emissions of different airlines, direct and indirect emissions, air traffic in various UK airports and fuel-efficient aircraft was collected from various sources like EU member states, Statista, Eurostat, IATA, CAA and EUROCONTROL. The results indicated that in 2019, commercial airlines carried over 4.5 × 10(9) passengers on scheduled flights. However, due to the COVID-19 pandemic in 2020, the global number of passengers was reduced to 1.8 × 10(9), representing around a 60% reduction in air traffic. Germany was the largest contributor to greenhouse gas (GHG) from the EU, releasing 927 kt of emissions in 3 years. In the UK, Heathrow airport had the highest number of passengers in 2019 with over 80 million, and the study of monthly aircraft movement revealed that Heathrow Airport also had the highest number of EU and International flights, while Edinburgh had the domestic flights in 2018. These research findings could be beneficial for airlines, policymakers and governments targeting the reduction of aircraft emissions. [Image: see text]

The global aviation industry has been increasingly urged to reduce their CO2 emissions. To achieve this, the International Air Transport Association (IATA) and International Civil Aviation Organization (ICAO) have successfully adopted various operational, technological, and air traffic management/infrastructural measures. However, they have also implemented market-based regulatory measures, including the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). Additionally, regional measures, such as the European emission trading system (ETS), nationwide political measures, such as flight taxes, and compensation programs by airlines also exist. Therefore, this study surveyed the impact of such measures, primarily on business travelers and their behavior, with a focus on Switzerland. Additionally, not only the impact of the first-last mile (airport access) was discussed, but also intermodal aspects like high-speed rails were debated. Results indicated that flight tax programs were found to have a weak impact on demand. The impact of COVID-19 was addressed and decreased travel frequency from COVID-19 may impact global flight emissions in the long term. Furthermore, passengers supported investments of flight-tax revenues in sustainable aviation technology; they did not support flight contingents. Conclusions are that taxes might generate additional airport traffic. An analysis about booking behaviors revealed fundamental differences in environmental terms. Finally, voluntary compensation was highly favored.

Demand for air travel is projected to increase in the upcoming years, with a corresponding influence on emissions, air quality, and public health. The trajectory of health impacts would be influenced by not just emissions growth, but also changes in nonaviation ambient concentrations that influence secondary fine particulate matter (PM2.5) formation, population growth and aging, and potential shifts in PM2.5 concentration‐response functions (CRFs). However, studies to date have not systematically evaluated the individual and joint contributions of these factors to health risk trajectories. In this study, we simulated emissions during landing and takeoff from aircraft at 99 airports across the United States for 2005 and for a 2025 flight activity projection scenario. We applied the Community Multiscale Air Quality (CMAQ) model with the Speciated Modeled Attainment Test (SMAT) to determine the contributions of these emissions to ambient concentrations, including scenarios with 2025 aircraft emissions and 2005 nonaviation air quality. We combined CMAQ outputs with PM2.5 mortality CRFs and population projections, and evaluated the influence of changing emissions, nonaviation concentrations, and population factors. Given these scenarios, aviation‐related health impacts would increase by a factor of 6.1 from 2005 to 2025, with a factor of 2.1 attributable to emissions, a factor of 1.3 attributable to population factors, and a factor of 2.3 attributable to changing nonaviation concentrations which enhance secondary PM2.5 formation. Our study emphasizes that the public health burden of aviation emissions would be significantly influenced by the joint effects of flight activity increases, nonaviation concentration changes, and population growth and aging.

Beginning January 1, 2012, most carbon dioxide emissions from commercial flights to, from, and within the European Union are covered by the EU Emission Trading Scheme. This report details why there is a need to address aviation emissions, how the EU's emissions trading scheme works, estimated impacts on U.S. airlines, and related materials.
