Is Scania ISO 14001 certified?
All production facilities are certified according to ISO 14001. Furthermore, development resources and central market units are also certified. Read more  

What does Scania have to offer customers who want to reduce their emissions as much as possible?
Scania’s main aim is to reduce emissions at source. With the introduction of Euro 4 engines, Scania has succeeded in reducing particulate emissions by 80% and nitrogen oxide emissions by 30% compared to Euro 3 - and that without any fuel penalty. Read more  

How does fuel quality influence emissions?
A cleaner fuel has an immediate favourable effect on emissions from all vehicles, regardless of their model year. Low sulphur content means decreased particle levels and low emissions of SOx which in turn reduces the risk of acidification. Low levels of aromatics helps engine development to focus on optimisation of the PM-NOx-fuel consumption trade off.

In some countries, for example Sweden, a special diesel fuel is already available with 10 ppm sulphur and a total aromatic content of 5%.  

Is not the use of alternative fuels the best way to reduce the environmental impact of transports?
It depends if talking about one single vehicle or a whole fleet of vehicles. At Scania we focus on improvements on commercially applicable vehicles. This adds up to bigger effects compared to a concept vehicle.

With the use of alternative fuels – if we by this mean non-fossil fuels there can be a decrease in CO2 and some of the other emissions as well. But the future of these fuels is not only depending on engine development. It is also a question of fuel availability, infrastructure and competitiveness. In the short term, pure bio fuels are not a good alternative since there is a shortage of them.

Scania is working with gas engines. Natural gas has a potential for urban traffic (buses) and distribution. But gases also have some drawbacks, since the handling of them is not easy and the tanks are heavy and bulky.

An exceptionally clean synthetic diesel fuel – ideally suited to tomorrow’s high-efficiency diesel engines – can be produced from various substances available today to provide even better preconditions for clean combustion. Synthetic diesel can be produced from natural gas or biomass, of which there are huge reserves. So diesel, in one form or another, will be used by heavy vehicles far into the 21st century. Read more  

Some manufacturers are investing heavily in future alternative fuel technology such as fuel cells. What is Scania doing in this area?
To increase knowledge of environmentally compatible technology, Scania has taken part in a European project to develop a fuel cell bus. It gave us important knowledge about the technology. However, for the foreseeable future it is not a realistic option for long haulage. Read more  

Are you preparing for the possibility of an “end-of-life” directive to apply to heavy duty vehicles in the future?
At present, heavy commercial vehicles are not encompassed by European manufacturers’ liability legislation. Scania has nonetheless produced dismantling information for its trucks so as to aid end-of-life treatment. Various components and materials are also marked to aid recycling.

In Japan, trucks are encompassed by manufacturers’ liability legislation. Read more  

How much of a Scania truck is recyclable?
The residue value of a truck is generally large enough to motivate dismantling of parts for reuse and recycling. By producing dismantling manuals and materials labelling, Scania strives to facilitate end-of-life treatment and to maintain a responsible handling of used trucks.

Most of a Scania truck consists of steel, which is easy to recycle. The degree of material recycling is therefore very high. Read more  

What is the material content of the new P- and R-series trucks?
The trucks consists mainly of steel (about 60%) and cast iron (about 20%). The remaining 20% include plastics, aluminium, rubber as well as other metals, glass, paint, oil and grease. Read more

What is the difference between the Euro 3 requirements and the corresponding requirements in the U.S.?
Euro 3 levels are slightly lower than the EPA 98 legislative levels. However, there is also a difference between test-cycles which makes the comparison inappropriate.
