"At the beginning of the century transport was merely a tool for locomotion. It served to get us to work, and helped us discover our own home and the wider world. In recent decades the private automobile has risen above the many other types of transport tools; it has had an unequalled carrier. At first it was just an object of our dreams, and then it became part of our everyday life. Now, however, it has grown to be a cancerous tumour on our brain. It destroys our health, eats up our material supplies and makes our cities unliveable. Luckily mankind has always found the cure for its troubles, ensuring its further survival. Today cures already exist against the automobile-god culture. These cures are called, collectively, environmental friendly transport policy." (Dr. Dezső Radó, 1998).

According to the OECD 'sustainable transport means transport that does not endanger the public health or the ecosystem, and which satisfies the demands for transport in such a way that renewable energy sources are used at a rate slower than that necessary for their replenishment and non-renewable sources are used-up at a rate slower than that needed to create the renewable sources that will substitute for them.'

One of the main goals of the Clean Air Action Group is to contribute to the actualisation of an environmentally friendly sustainable transport policy. This means a transport policy that:

- reduces to the lowest possible level the damaging effects on the environment and nature, the consumption of energy and land as well as the economic and social costs;
- creates the greatest security possible for both the vehicle operator and passenger as well as for society as a whole; and
- ensures the fewest obstacles possible to mobility and availability, which are necessary for sustainable development.

In the interest of these goals the Clean Air Action Group promotes:
- the creation of safe, healthy and pleasant circumstances for the pedestrian--with special attention to children;
- the reduction of traffic-caused pollution to a level that is in balance with the capacity of nature (including that of the human organism) to bear it;
- increased and widespread use of bicycles for transport;
- the modernisation and development of public transport;
- the development of rail transport and an increase in its use compared to that of road transport;
- improvement in the conditions of that motor vehicle traffic which is absolutely necessary for sustainable social and economic development;
- increased opportunities for the public to take part in decisions relating to transport;
- assertion of the polluter-pays principle in transportation;
- the most economical transport solutions possible;
- a significant increase in traffic safety;
- the creation and execution of community-policy leading to reduction in motor vehicle traffic;
- such technical and other similar development (for example, telecommunications development) that contributes to the situation where certain activities can be carried out more effectively with reduced demand for motor vehicle transport;
- alleviation of the transport problems of disabled people; and
- environmentally friendly motor vehicle solutions.
