Jigsaw illustrating environmental and health effects of transport

Transport affects the health of the whole population both directly and through pollution of the environment. Transport emissions are also one of the major contributors to climate change.

Main health effects include injuries from road traffic accidents, respiratory problems due to air pollution, overweight/obesity associated to reduced physical activity and noise annoyances. Vulnerable groups include children and the elderly, as well as cyclist and pedestrians.

How does WHO help?

WHO supports its Member States in defining and managing mobility policies that are beneficial to health by developing methods and tools to assess the health impact of transport.

WHO also promotes a sustainable transport for health and the environment through an integrated and synergic approach that aims to prevent and reduce the health effects associated to current unsustainable transport patterns.

What is health impact assessment (HIA)?

HIA aims at studying upstream health determinants in an integrated way rather than concentrating on single risk factors. Its overall objective is to provide decision-makers with sound information on implications on health of any given policy.
