Calculation of Paris-compatible emission paths and emission targets with the ESPM:
The ESPM consists of two calculation steps:
(here is a brief background paper on the ESPM)
Step 1: Determination of a national budget
Step 2: Derive plausible emission paths that adhere to this budget
What is calculated? |

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, |
|
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. |

step 1: budget |
The user must generally define the budget themselves (see tools in the right-hand column for possible support). The Excel tool for calculating national CO2 budgets (see right-hand column) can be linked to this Excel tool so that the emissions data of all countries in the world and the national budgets calculated there are also available in this tool. The Excel tool furthermore contains emissions data for the EU, Germany and global data. For the EU and Germany, national CO2 budgets can also be determined using the weighting model. |
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 tool use the Regensburg Model Scenario Types (here is a brief description). |
The tool also indicates the year of emissions neutrality based on a linear emissions path. |
