See how countries include transport measures in their national climate plans (NDCs). Based on each country's latest available NDC, the chart shows the share featuring each transport measure type and the top five countries by category.
The data are based on an analysis conducted by the ifeu - Institute for Energy and Environmental Research Heidelberg, using the German Emission Inventory Model (TREMOD) and information from the German Federal Motor Transport Authority (KBA). Vehicle stock and new registrations refer to December 31 of each year. The sharp decline in new registrations in 2020 is primarily attributable to the effects of the COVID-19 pandemic.
The dashboard consolidates a structured collection of transport-related indicators for G20 member countries. It integrates data on population, urbanisation, mobility patterns, energy use, greenhouse gas emissions, electric vehicle deployment, national and NDC transport targets, biofuels, subsidies, hydrogen, batteries, and relevant policies.

The data are based on an analysis conducted by the ifeu - Institute for Energy and Environmental Research Heidelberg, using the German Emission Inventory Model (TREMOD) and information from the German Federal Motor Transport Authority (KBA). In Germany, half of the stock is below 10 years of age, but almost 5 million cars remain in the stock which are more than 20 years old. This leads to the fact that the average age of cars is 10.6 years in 2024.
