calculation of Paris-compatible national CO2 budgets for all countries in the world

which emissions

freely specifiable

all CO2 emissions
(including land-use change; LUC/LULUCF)

Which emissions are covered depends on the database used (see instructions for the apps).

step 1: budget

The user must set the budget himself (see tools in the column on the far right as a possible support).

To derive a national CO2 budget from a predefined global CO2 budget,
a weighting model is offered that takes into account the country's share of the world population and of global emissions.

step 2: paths

To calculate the emission paths, the tools use the Regensburg Model Scenario Types (here is a brief description). These scenario types represent the entire range of plausible emission paths. Which scenario type makes sense in each case must be decided scientifically based on an overall climate policy view.

The web apps also show emission targets based on linear emission paths; particular for the six major emitters.

For more options in determining emission paths: The national budgets determined in the first step can then be used in the paths web app or in the corresponding Excel tool (see left column below) to derive plausible national emission paths with the RM Scenariot Types.
