Transport drives economic activity and is fundamental to human welfare, but the sector is also a major source of greenhouse gas emissions and other forms of pollution, with 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’s largely because 95 per cent of the world's transport energy still comes from fossil fuels.
At UN Environment, we are working to break the link between increased mobility and increased emissions. We believe that low-carbon mobility can reduce pollution while also creating jobs, making streets safer, strengthening infrastructure and stimulating local economies. We are 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.
