Michelin's 'Green Paper' from Chengdu on challenges ahead

Road accidents, pollution, climate change and congestion are among the crucial challenges of modern life.

Statistics show that by 2050, there will be 2.5 billion more people on the planet and 70 percent of the world's population will live in cities, compared with 50 percent today.

To develop a shared vision of sustainable mobility and work out concrete solutions to generate real benefits for people, companies and society, French tire maker Michelin brought its 12th Challenge Bibendum to Chengdu this year, making China the first country to host the event three times.
