On own road to green revolution

Smog blurred the skyline Wednesday morning as I opened the curtain of my hotel room in Tianjin. The day was hot and stifling; the heat and CO2 seemed to be trapped beneath a blanket of smog.

"We have quite a few days like this," my taxi driver told me as she took me to the Tianjin railway station.

"There are so many cars are on the road these days; still, I feel the authorities should put a stricter cap on car emissions," she said.
