Driving and the environment is about how your driving technique, planning and vehicle choice reduce emissions, fuel use and noise. This is important both for the theory test and to become a more responsible road user.
Before you continue, see the introduction in Introduction to the theory test.
Why driving affects the environment
Modern vehicles emit greenhouse gases, particles and noise that affect local air quality and the global climate. Key factors:
- Fuel/energy use and COâ‚‚ emissions
- Air pollution (NOâ‚“ and particles)
- Noise in urban areas
- Resource use in production and maintenance
Speed and fuel use
Speed strongly affects consumption. Typical increase at higher speeds:
Speed | Extra consumption |
---|---|
80 km/h | Reference |
90 km/h | +10% |
100 km/h | +20% |
110 km/h | +30% |
120 km/h | +40% |
Tips for speed choice:
- Keep a steady speed, avoid unnecessary accelerations
- Use cruise control on motorways
- Reduce speed gradually instead of harsh braking
Trip planning
Good planning can halve kilometres driven:
- Combine errands into one trip
- Pick routes with fewer stops and smooth flow
- Avoid rush hours when possible; see City driving
Maintenance and tyre pressure
Proper maintenance reduces consumption and emissions:
- Check tyre pressure monthly
- Service on schedule
- Replace air filter and engine oil as specified
Pressure deviation | Extra consumption |
---|---|
0.5 bar low | +3% |
1.0 bar low | +7% |
Vehicle choice
When choosing a car, consider environmental aspects:
- EVs for zero local emissions
- Consider hybrids or small petrol/diesel cars
- See Choosing a car
Alternative transport
Sometimes other modes are better:
- Public transport for commuting
- Cycling and walking for short distances
- Car‑sharing and pooling to reduce cars on the road
Financial benefits
Eco‑driving often saves money:
Cost type | Saving |
---|---|
Fuel/energy | 15–30% |
Maintenance | 5–10% |
Tolls and fees | 10–20% |

Conclusion
Driving and the environment combines technique, planning and choices. Apply these principles to reduce environmental impact and costs, while improving air quality and sustainability. Start today with small changes—every action counts.
