Methods
Description of Index decomposition analysis (IDA):
- A changing variable such as sectoral CO2 emissions over a time period (2020-2050) is decomposed into its factors of influence such as the sectoral activity, its energy efficiency, and its CO2 intensity
- Identification of key driving forces and levers of emission changes over time
- Results of the updated first and second modelling rounds, consisting of the "Where we are headed" (WWH) and Net Zero Emissions (NZE) scenarios for the EU28
- The IDA allows identifying the chosen emission reduction levers for different scenarios within one model as well as between models.
- IDA aims to improve the link between climate science and policy by increasing the transparency on the range of contributions from CO2 reduction levers
- Comparison of the results of different energy-system and integrated assessment models available in the project with the sector models, FORECAST and ALADIN
- Based on selected indicators such as electrification rate and CO2 intensity.
- WWH and NZE scenarios
- ALADIN and FORECAST used as a benchmark to assess the ranges of several indicator results of the EU models over time.
