German Obsession with Grand Vehicles Stuck in Gridlocks: A Celebration of Grandeur on Wheels
The transport sector continues to struggle with meeting its CO2 targets, a problem that requires a fundamental change in mobility thinking to address. In 2024, Germany saw a decrease in the average distance travelled by each passenger car, with an average of 12,309 km, a decrease of 1,802 km compared to 2014. However, this progress is overshadowed by the increasing size of cars, particularly SUVs, which no longer fit into normal parking spaces.
In the same year, SUVs accounted for 30 percent of registrations in Germany, highlighting the contrast between driving less and the growing size of cars. To curb this car flood, higher parking fees for larger vehicles like SUVs could be a potential method.
The need for this fundamental change is not a luxury, but a necessary reality. The solution to reducing the car flood and addressing climate issues in the transport sector lies in fewer, but efficiently used vehicles.
In 2024, there were 49.1 million passenger cars registered in Germany. Transitioning these vehicles to smaller, energy-efficient models could significantly reduce emissions. However, electric cars cannot be made too small due to construction constraints, as the batteries would be too small and the vehicles would have insufficient range.
The automotive industry does not have a strong incentive to build small cars, especially electric ones. Yet, incentives for smaller, energy-efficient vehicles offer a promising solution. These incentives often involve encouraging the adoption of electric vehicles (EVs) and improving the efficiency of internal combustion engines.
Solutions for reducing carbon emissions in the automotive sector also include eco-driving training and measures, optimising vehicle usage, route and trip optimization, encouraging public transportation, flexible regulatory strategies, and the use of low-carbon fuels and engine improvements.
Eco-driving training can reduce fuel use by 10–15% by promoting smooth acceleration, speed control, and route optimization. Use of AI-based tools to dynamically adjust vehicle speeds can cut emissions by 11 to 22% without slowing traffic flow.
Optimising vehicle usage through internal car-sharing, vehicle pools, and digital booking increases utilisation efficiency, reducing the total number of vehicles needed and therefore emissions. Route and trip optimization using geolocation technologies helps avoid unnecessary detours, groups deliveries, and supports remote work, all contributing to lower emissions.
Encouraging public transportation and its efficient usage reduces individual vehicle use. Investment in clean, zero-emission public transit vehicles alongside promoting a shift from private cars to buses and trains can significantly decrease per capita transport emissions.
Flexible regulatory strategies supporting zero-emission vehicle credits and pooling across regions encourage manufacturers to produce smaller, cleaner vehicles and meet emissions targets more cost-effectively. The use of low-carbon fuels and engine improvements for internal combustion engines provide near-term emission reductions and complement the gradual shift to zero-emission vehicles.
Looking beyond Germany, countries like Japan have already embraced this approach. In 2020, Kei-cars, which are small cars with specific dimensions and engine power, accounted for around 40 percent of all passenger cars registered in Japan.
In essence, a robust approach mixes incentives for smaller, energy-efficient cars—especially electric vehicles—and technologies promoting eco-driving and route optimization, combined with enhanced, clean public transit systems. Regulatory frameworks that support manufacturer flexibility in deploying zero-emission vehicles further promote emission reductions in the automotive sector.
It is clear that the next SUV upgrade is not the solution to the problem of reducing cars and addressing climate issues in the transport sector. Instead, a focus on smaller, energy-efficient vehicles, combined with a shift towards public transportation and eco-friendly driving practices, offers a promising path forward.
