COIN-INT2.0 is a multi-regional and multi-sectoral model of the global economy, which is tailored to the analysis of macroeconomic effects of climate policy with a European focus. Within ACCREU, the model is expanded by a set of impact and adaptation modules covering a range of different climate impacts under three Representative Concentration Pathways (RCPs) and three different adaptation levels until 2080. For a detailed description of the model extensions, refer to the Technical documentation of COIN-INT model extensions within the ACCREU project.

The folder structure below describes the organization of the underlying data on the IIASA Accelerator.
| Variable | Description |
|---|---|
| GDP_real | real GDP |
| welfare | total welfare, composed of private and public welfare (Hicksian equivalent vairation with impact-specific adjustments |
| tax_revenue | public tax revenue (equivalent to total public expenditure due to budget-neutral assumption |
Results are listed for 3 RCPs (RCP2p6, RCP4p5, RCP7p0), the baseline without climate impacts nor adaptation (no_impact), and 3 scenarios with impacts and 3 adaptation levels (low_ada, medium_ada, high_ada), for 25 European regions, in yearly aggregates for the years 2020-2080 in 5-year steps.

The D4_3_Fiscal_COIN/ directory contains six Excel files presenting COIN-INT macroeconomic impacts and adaptation scenarios.
The files cover agricultural impacts, flooding, health impacts, labour productivity impacts, and sea-level rise, alongside a combined dataset covering all impacts.

This dataset was produced as part of the ACCREU (Assessing Climate Change Risk in Europe) project, funded by the European Union’s Horizon Europe research and innovation programme under Grant Agreement No. 101081358.
The macroeconomic and fiscal simulations were conducted using the COIN-INT2.0 model, developed at the Wegner Center for Climate and Global Change, University of Graz. The underlying data files are hosted on the IIASA Accelerator platform.
