This paper surveys climate and energy policy in the EU transport sector covering the road,
aviation, and shipping sectors. We summarise current policies, focusing on the Fit for 55 …

Aviation is the backbone of our modern society. In 2019, around 4.5 billion passengers
travelled through the air. However, at the same time, aviation was also responsible for …

Aviation is an important contributor to the global economy, satisfying society's mobility
needs. It contributes to climate change through CO2 and non-CO2 effects, including contrail …

To limit air transport's climate relevant emissions, two important CO 2 trading schemes for
aviation are in force, or will be in the future: The EU Emissions Trading Scheme (EU ETS) for …

The compact Earth system model OSCARv2. 2 is used to assess the climate impact of
present and future civil aviation carbon dioxide (CO2) emissions. The impact of aviation CO2 …

Persistent contrails and contrail cirrus are responsible for a large part of aviation induced
radiative forcing. A considerable fraction of their warming effect could be eliminated by …

Throughout spring and summer 2020, ozone stations in the northern extratropics recorded
unusually low ozone in the free troposphere. From April to August, and from 1 to 8 kilometers …

In this paper, the broader perspective of green hydrogen (H2) supply and refueling systems
for aircraft is provided as an enabling technology brick for more climate friendly, H2-powered …

Even though the contribution of the aviation sector to the global economy is very notable, it
also has an adverse impact on climate change. Improvements have been made in different …

One of aviation's major challenges for the upcoming decades is the reduction in its climate
impact. As synthetic kerosene and green hydrogen are two promising candidates, their …
