UNEP promotes sustainable low-emission transport and works to reduce the sector’s contribution to air pollution and climate change.

Transport drives economic activity and is fundamental to human welfare, but the sector has significant impacts on the environment and human health.

Transport activity is increasing around the world as economies grow, which means that the sector’s emissions are also on the rise. That is largely because 95 per cent of the world's transport energy still comes from fossil fuels.

The United Nations Environment Programme (UNEP) works to break the link between increased mobility and increased emissions.

UNEP believes that low-carbon mobility can reduce pollution while also creating jobs, making streets safer, strengthening infrastructure and stimulating local economies.

UNEP is a partner in several leading global transport programmes in areas such as fuel economy, small particulate pollution and infrastructure development, some of which are implemented through public-private partnerships.


The work of UNEP on transport is led by the Transport Section.
