greenhouse gas

Should countries be allowed to buy greenhouse gas quotas from other countries and so, in effect, pay for the right to pollute more? Or should polluters simply be heavily taxed if they exceed their own quotas?

Since the beginning of the Industrial Revolution, the concentrations of most of the greenhouse gases have increased. For example, the mole fraction of carbon dioxide has increased by about 36% to 380 ppm, or 100 ppm over modern pre-industrial levels. The first 50 ppm increase took place in about 200 years, from the start of the Industrial Revolution to around 1973; however the next 50 ppm increase took place in about 33 years, from 1973 to 2006.

The term 'greenhouse gases' refers to various gases in the Earth's atmosphere, which are typically characterized by their ability to absorb infrared radiations coming from the Sun. The entire process wherein the Sun's infrared radiations are trapped within the atmosphere by these greenhouse gases is referred to as the 'greenhouse effect'. Greenhouse gases list includes gases such as carbon dioxide, carbon monoxide, methane, chlorofluorocarbons, etc., - some of which stay in the atmosphere for several years and contribute to the greenhouse effect on the planet. The atmospheric concentration of these gases is one of the main causes of the greenhouse effect. Global warming, on the other hand, refers to an incessant rise in global average temperature triggered by various natural and anthropogenic causes - greenhouse gases being one of them.
