Eco Driving Calculator
See the environmental and financial impact of driving more smoothly. Compare your current consumption with a calmer style to find the fuel, money and CO₂ you can save each year.
How it works
Each litre of petrol burned releases about 2.31 kg of CO₂ (diesel ≈ 2.68 kg/L), so cutting fuel use cuts emissions directly. Smooth acceleration, maintaining a steady speed, anticipating traffic and removing roof loads are the highest-impact habits.
Frequently asked questions
What habits reduce consumption most?
Anticipating traffic to avoid braking, accelerating gently, holding a steady motorway speed, removing roof racks, and keeping tyres at the correct pressure are the biggest wins.
How is CO₂ per litre calculated?
The official conversion factors are about 2.31 kg CO₂ per litre of petrol and 2.68 kg per litre of diesel, reflecting the carbon released when the fuel is burned.
