China’s 474 million-strong consuming class is starting to wonder whether the price they’ve paid for prosperity is worth it, if money can’t safeguard health. Too severe to be ignored, environmental concerns in China are finally beginning to trump economic ones.

China has severe pollution problems – it's home to seven of the world’s ten most polluted cities. A number of business models have been spawned off the back of it, from pollution-removing photo apps to Uber’s collaboration with Tesla. And now? Fashionable face masks.

In response to high pollution levels in Paris, the government has imposed a car ban with a difference. People with odd and even-numbered license plates alternate driving duties, meaning they only have the chance to drive every other day.
