About the project
The Net-Zero Navigator is a platform of the Bertelsmann Stiftung's Sustainable Economy project.
The Navigator has been available since 2024. The tool's current data horizon is 2022; previous years' data are entered into the Navigator at the end of each calendar year.

Model assumptions
The Net-Zero Navigator aims to visualize a complex world in an intuitively understandable way. The following model assumptions are made for this purpose:
1. reduction pathways based on an average annual percentage reduction in GHG emissions are assumed for the achievement of national climate neutrality targets.
2. The goal of climate neutrality allows each country an individual level of residual emissions that can realistically be offset. The information provided by the countries in their UN LT-LEDS is primarily used as the basis for calculating these residual emissions. For countries that have not provided specific information on residual emissions in their strategy reports, estimated values based on the relative economic power of the countries are used.
3. For the variable “Climate neutral in” in the Navigator's country overview, only the emissions reduction during the current year selected in the tool is taken into account. This means that the Navigator calculates for each country when the target of climate neutrality would be achieved if the country were to reduce emissions every year from now on to the same extent as it did in the selected year.
4. The classification into colored quintiles in the Navigator country and region comparison is calculated individually for each KPI based on the minimum and maximum values in the most recent year (2023). The quintiles are therefore comparable over the years and show in each year how well or poorly developed a KPI is for a country in that year relative to the 2023 framework values.
Data
The Net-Zero Navigator obtains the majority of its data from the EDGAR Project database.
The EDGAR (Emissions Database for Global Atmospheric Research) Community GHG Database, is a collaboration between the European Commission, the Joint Research Center (JRC), the International Energy Agency (IEA) and includes the datasets IEA-EDGAR CO2, EDGAR CH4, EDGAR N2O, EDGAR F-GASES version 8.0, (2023) European Commission, JRC (Datasets).
Additional data on regional GDP and population development comes from the European Commission's ARDECO Explorer.
Existing data from the above-mentioned datasets were used to calculate new, proprietary KPIs.
