Basic idea behind the Regensburg Model (RM) Global paths: Global emission paths are determined that are compatible with a global CO2 budget to be specified. For this purpose, the tool provides the Regensburg Model Scenario Types RM 1 - 6 (see Technical note). National paths: National emission paths are derived from this global paths with the Regensburg Formula, which leads to the convergence of per capita emissions. Central features of the Regensburg Formula: monotonic paths in the convergence period countries that start with per capita emissions below the convergence level will never exceed this convergence level countries that start above the convergence level with per capita emissions must reduce their emissions from the outset results represent a kind of “moral lower limit” for industrialized countries if the convergence level is chosen relatively low Here is a preview of the tool. The macros in the Excel tool are signed with a certificate from Sectigo. Simplified web app for the Regensburg Model: http://rm.climate-calculator.info
