From Resource Exploitation to Nature Restoration: Unlocking the Potential of Agroforestry Systems as Feedstock Provisioners for Sustainable Composite Manufacturing: An LCA study of bio-based carbon fibre precursors for aviation composites

This research investigates alternative biomass feedstocks for environmentally improved composites in the aviation industry. It addresses challenges and opportunities associated with biomass use and proposes a sustainable biomass feedstock for bio-methanol production as a carbon fibre precursor for composites. The aim is to evaluate the...

Assessing the appropriateness of different climate modelling approaches for the estimation of aviation NOx climate effects

Aviation’s contribution to anthropogenic global warming is estimated to be between 3 – 5% [1]. This assessment comprises two contributions: the well understood atmospheric impact of carbon dioxide (CO2) and the more uncertain non-CO2 effects. The latter pertain to persistent contrails and pollutants like nitrogen oxides (NOx), water vapor (H2O),...

Climate Impact of Hydrogen Aviation: Research on the variations of surface temperature change caused by hydrogen and kerosene combustion aircraft

Concerned about rapidly rising temperatures, international institutions, nations, and companies worldwide examine how to reduce emissions in all economic sectors. Inside the aerospace sector, it is believed that hydrogen technology has the potential to be the best asset to fight global warming. This thesis aims to create and use a methodology to...

An Assessment of the Future Climate Impact of Commercial Aviation Activity: A Scenario-Based Assessment Approach

Aviation activity results in around 5% of global climate impact, for which both the sources and the manner to improve through technology, operations, and policy need to be better understood. Therefore, a Scenario-based assessment through AirClim is done, assessing future efforts and their support for the Paris Agreement goals. The baseline...

Sensitivity study of engine design parameters to climate impact

In the last few years, there has been a growing awareness regarding the climate impact of aviation in the general public. With global warming effects becoming more severe, it is important that aviation drastically reduce its emission footprint to keep the impact on the climate lower. There have been ongoing efforts by various organizations such...

Mitigation of non-CO₂ aviation’s climate impact by changing cruise altitudes

Aviation is seeking for ways to reduce its climate impact caused by CO₂ emissions and non-CO₂ effects. Operational measures which change overall flight altitude have the potential to reduce climate impact of individual effects, comprising CO₂ but in particular non-CO₂ effects. We study the impact of...
