New Technology : Carbon Capture（捕获）

To reduce CO₂ in the air, the European Union has set up strict regulations (法规) over the past few years, and most European car companies have begun to move to electric vehicle（交通工具）production under the new regulations. However, their efforts are far from enough. 

Planting trees can cut down CO₂ in the air, but just doing this isn't enough to deal with climate change. Now one way discussed widely is carbon capture. It refers to the technology that can protect the earth against climate change by cutting down CO₂ in the air. Carbon capture technology is used to collect CO₂ that is given off by factories. For example, it can be fitted to coal-burning power stations and factories to capture the CO₂ before it is given off by factories. The captured CO₂ can then be liquefied（液化）and stored underground. Besides, the technology can also be used to collect the CO₂ that has already gone into the air.

Then how can we deal with the CO₂ we capture? Proper utilization is truly important. It can not only help create markets for this new technology, but also make it cheaper for companies to use. Nowadays, CO₂ is used in greenhouses to grow vegetables. CO₂ can even be used to make useful products, such as plastics, building materials, and plants. 

Carbon capture is considered to be quite helpful. However, there are many problems on the way. There's 50 billion tons of carbon going out into the air from cars and factories every year. But even a great number of carbon capture machines now can capture only a few dozens of tons of it. The thickness of CO₂, in the open air is about 300 times less than that in the power stations or factories, making it much less efficient to capture CO₂. Because of this, carbon capture machines are very expensive today. So, it's hard to make a real difference in fighting climate change now. But it will be improved quickly and will become cheaper and more efficient. It is like the mobile phones which were expensive and difficult to use 20 years ago. But now mobile phones have been greatly improved.
