According to the International Labour Organization’s latest figures,  women make up just 16.8% of those working in transport globally. This makes it one of the worst-performing industries worldwide- both across the public and private sectors, from boardroom to engine room. Improving gender diversity in the transport sector workforce is essential to achieve its innovation, sustainability and financial goals, while tackling the current, and profound, skills shortage. This paper provides an insight into the challenges and opportunities women face when they choose to work in transport. It is grounded in a review of published literature and primary data collection among a sample of men and women working in the sector. The findings offer an overview of women’s global employment in transport, including all modes and sectors of transport. The study is presented as a toolkit highlighting the challenges women face when entering, working, and progressing in the transport sector, identifying five main areas or entry points where actions and measures could provide the most impact in accelerating gender balance and some 25 case studies. This paper presents the main findings from the study.
