When planning your journeys, how can you make them environmentally-friendlier?

The selected combination of actions is correct because they all contribute to reducing environmental impact when planning journeys.

1. Combining several destinations into one trip minimizes the number of journeys you make, which reduces fuel consumption and emissions.
2. Forming car pools encourages shared vehicle use, leading to fewer cars on the road, which also cuts down on pollution and traffic congestion.
3. Planning to use public transport instead of your own vehicle is a great way to lower your carbon footprint, as public transport typically generates less pollution per passenger.

Understanding these options is important under German traffic regulations, which emphasize sustainability and environmental protection. Promoting these practices aligns with Germany's commitment to reducing greenhouse gas emissions and improving air quality. Therefore, selecting all relevant actions not only complies with regulations but also fosters a greener transport culture.
