China is the world's largest emitter of greenhouse gases.

Many Chinese dream of seeing blue skies and white clouds but rarely do because of the smog. Often the daily routine is to wake up and check the pollution levels to decide if it is safe for children to play outside, or if a filter mask should be worn for protection.

Ahead of December's UN Climate Change summit, Peter Day reports on the Chinese ambitions to make China 'go green'. Many people say the Chinese aren't given enough credit for their efforts and argue the West will be shocked when it realises the extent of their actions. But can that ambition become reality? Peter Day reports from Beijing and beyond and asks when will the Chinese be able to breathe more easily?
