What can contribute to environmentally-friendly driving?

The combination of options 1, 2, and 3 all contribute significantly to environmentally-friendly driving.

1. Attending a practical driving training session for a fuel-efficient driving style teaches drivers techniques to enhance fuel efficiency, reduce emissions, and lower fuel consumption. This aligns with German initiatives aimed at promoting eco-friendly driving habits.

2. Using vehicles with an electric drive is a pivotal step towards reducing greenhouse gas emissions. Germany actively supports the transition to electric vehicles through incentives and infrastructure development, which helps in achieving targets set by climate protection policies.

3. Forming car pools reduces the number of vehicles on the road, directly impacting traffic congestion and lowering overall emissions. This practice is encouraged in Germany as a way to promote sustainable travel and enhance urban mobility while minimizing the environmental impact.

In conclusion, selecting all three options reflects a comprehensive understanding of various approaches that can be taken to foster environmentally-friendly driving practices. Each option plays a crucial role in contributing to a cleaner environment and aligns with German traffic regulations promoting sustainability.
