SWD/2021/603 final
This webpage provides a comprehensive overview of model use for the "SWD/2021/603 final" impact assessment. It aims to provide understanding of who ran the models, model ownership and the role models played in the impact assessment.
Who Ran the Models
2 models were run by external institutions
- AIM: UCL ATA
- E3ME: Cambridge Econometrics
Model Use Summary
AIM - Aviation Integrated Model
The AIM model was used to assess the impacts of options on the aviation sector, including direct and net aviation CO2 emissions, the percentage of global aviation CO2 emissions covered, carbon costs as a proportion of airline fuel and operating costs, impacts on demand for passenger and freight transport, demand for EU allowances and CORSIA offsets, auctioning revenues, ticket prices, and other externalities including from congestion and local air pollutants.
Role: baseline and assessment of policy options
Run by: UCL ATA
Ownership: Third-party ownership (commercial companies, Member States, other organisations, …)
E3ME - Energy - Environment - Economy Model for Europe
The E3ME model used the outputs from the AIM model (per capita aviation spending, fuel demand, and EU ETS revenues) to estimate social and economic impacts outside the aviation sector of changes in demand for air transport and air transport fuels and use of auctioning revenues from aviation EU ETS, including on GVA and employment.
Role: baseline and assessment of policy options

Ownership: Third-party ownership (commercial companies, Member States, other organisations, …)
