Web app Regensburg Model:
Calculation of Paris-compatible emission paths with converging per capita emissions

In the Regensburg Model, national emission paths are derived from a global emission path using the Regensburg Formula which leads to converging per capita emissions.

In the Regensburg Model, six scenario types (RM 1 - 6) are offered to derive global emission paths that adhere to a predefined CO2 budget. Here is a brief description of the scenario types.

Important framework data in the following web app (these can be freely set in the detailed Excel tool; see below):

► Global CO2 budget 2020 - 2100: 400 Gt, 550 Gt or 650 Gt (see indication in the app)

► Separate CO2 budgets at global level 2020 - 2100:

► Minimum global CO2 emissions by 2100: -0.7 Gt

► Convergence level: 0.5 t per capita

When you select a country, you can see the resulting emission paths, reference values and other key figures.

In the corresponding tab you can see the underlayed global paths.
