Citroen encourages the use of biofuels, e.g., biodiesel (a blend of diesel fuel and ethanol) & bioethanol (blend of petrol & ethanol).
In some countries such as Brazil and Sweden, Citroen sell vehicles using “FlexFuel” technology, which can run on up to 85% ethanol.
Furthermore, Citroen have a system to manage waste batteries and ensure they are disposed of properly.
Citroen also has a section on their website called “eco-driving”. This explains methods to save fuel whilst driving, such as selecting the right gear, speed control and tyre pressure:Car manufacturers
Our world is constantly on the move. Because of expanding economies and international trade, transportation-related energy demand will increase by more than 40 percent from 2010 to 2040. Most of this demand is driven by commercial sources such as trucks, planes, ships and trains. At the same time, personal vehicles are becoming significantly more energy-efficient. Although the number of cars on the road will about double, advances in automotive technology (such as hybrid cars) keep global personal transportation energy demands relatively steady.
