Climate assessment of innovative mitigation strategies towards operational improvements in aviation
Duration: 1.July.2020 - 31.June.2023
The project "CLIMOP Climate assessment of innovative mitigation strategies towards operational improvements in aviation), coordinated by Deep Blue and supported by the DLR Institutes of Air Transport and of Atmospheric Physics, investigates different operational measures to reduce the climate impact of aviation. Both changes in CO2 and non-CO2 effects of aviation and impacts on the different stakeholders of the aviation system are investigated. These include, for example, impacts on passenger acceptance, safety, operating costs, or airspace utilization that are influenced by the implementation of such mitigation measures. Based on a comparative assessment of different operational improvements on ground and in-flight, harmonized strategies will be developed to enable the implementation of the identified improvements and thus the realization of the identified potentials. Recommendations for regulations and policies will be formulated in this context.
The Institute of Air Transport is taking the lead in the work package dealing with the quantitative assessment of CO2 and non-CO2 effects on the climate through operational improvements. The selection of measures to be investigated in detail was coordinated and an assessment of the following operational improvements was conducted using climate and stakeholder metrics:
- Flying lower and slower
- Free routing
- Wind-optimal routing
- Climate-optimized trajectories
- Climate-optimized network planning
- Climate-optimized intermediate stop operation
- Sustainable taxi operations
- Electrification of ground vehicles
- Upgrade of airport infrastructure
The evaluation of the individual measures "Flying lower and slower" and "Climate-optimized intermediate stop operations" was mainly carried out at the Institute of Air Transport, while the other measures were analyzed by partners of the consortium. Based on the individual results, a comparative methodology is developed and applied to compare the effectiveness and efficiency of the individual measures.
