Purpose and goal
Flying affects the climate in many ways in addition to its emissions of carbon dioxide. The purpose of the project is to increase understanding of how these non-CO2 effects can be valued and how they can be reduced with regulations and policy measures. The specific goals with the project are to A) calculate the climate impact of contrails and other non-CO2 impacts for different motor and fuel types. B) estimate the social cost of contrails. C) Analyze possible regulations and policy measures to the reduce the climate impact of contrails.
Expected effects and result
The project´s results are expected to lead to aviation´s climate impact being able to be reduced via regulations and control measures aimed at reducing the impact of contrails. To achieve this, the project will lead to: *A trained postdoctoral fellow focusing on aviation´s climate impact and possible control measures to reduce these. *Several research articles on, among other things, contrails, their social costs, and cost-effective policy design. *A popular science article or debate article. *A network of researchers and stakeholders.
Planned approach and implementation
The project consists of the following work packages (WP): WP1 - physical climate modeling with a focus on how contrails and other climate effects are affected by alternative fuels and engines. WP2 - Calculation of the social costs of contrails with integrated climate-economic modelling. WP3 - Analysis of cost-effective policy measures to reduce the climate impact of contrails.
