Transport

Hannah Ritchie; Max Roser

Transport allows people to move across cities, countries, and continents. It allows us to trade goods and products across the world by road, rail, sea or air.

It has become an essential part of our lives, whether itâ€™s getting to work or school; delivering essential services or necessities to different communities; or connecting people and industries across the world. Itâ€™s now a key driver of economic development.

But transport also negatively affects our health and the environment through road injuries and fatalities, air pollution, and COâ‚‚ emissions which drive climate change.

On this page, you can find data, visualizations, and writing on transport patterns across the world, how this is changing, and its environmental impacts.

Transport, food, and COâ‚‚ emissions

You want to reduce the carbon footprint of your food? Focus on what you eat, not whether your food is local

Very little of global food is transported by air; this greatly reduces the climate benefits of eating local
