As the representatives of nearly 200 countries struggle over an agreement, in Doha, to fight global warming, people here in China are already taking steps to reduce carbon emissions. CCTV reporter Han Peng visits one family to see how they're doing their bit to save energy.

Another busy Monday morning, Li Zhenqi is a project manager working with a multinational company in Beijing.

The businessman believes that efficiency is a way of life that not only affects the pace of work, but also the use of energy.

Every day, the high-paid manager drives a low-emission car to work... and before he arrives in his company, he would often pick up two of his colleagues who live nearby.

Yang Zhenqi, Businessman, said, "In the past, my colleagues all drove their own cars to work. But we all feel there are too many cars on the road, and petrol is not cheap. If we can manage to operate a car pool, why not do it? It's good for all of us, and helps to reduce carbon emissions."

As Li heads off to his company, his wife is also in a hurry to go to work.

Although she has a car of her own, more often than not, she chooses to use the subway instead of driving. She says taking subway has already become her lifestyle, as it's more convenient and energy-saving.

But hold on for a moment, before she leaves home, there′s something very important for the lady, turning down the central heating in the apartment -- the latest carbon-reducing project installed by the Chinese government.

Yuan Fang, Office Clerk, said, "In the past, all households were given an equal amount of heating, whether you needed it or not. But last year, the government installed this switch. When I don't need it to be too hot, or when we go out, I can turn down the temperature. That saves energy, and of course saves money."

Heating swallows up over 10 percent of China's energy, and claims an even larger proportion of carbon emission, as most heating is provided by coal plants.

To change this, China began to introduce the adjustable heating system. By last year, one in three buildings had the adjustable system installed.

As Chinese people struggle to make a change, without coordinated efforts in the world, the situation of climate change continues to worsen. 2012 is on track to become one of the top 10 hottest years on record. And the UN says ice in the Arctic is melting at, quote, "an alarming rate".

Across China, hundreds of millions of families are doing everything they can, everyday, to reduce carbon emissions and counter climate change. Although each individual contribution may be just a drop in the ocean, compared to the huge amount of carbon emissions released into the environment by industries the world over, the moral of this story is the growing awareness of the urgency of the problem.
