Global environmental situation

G8 summit about environment will be held in Germany from June 6. The main topic is global warming. Kyoto protocol which orders developed countries to reduce CO2 will be took effort next year. So many countries should begin to reduce CO2. But they should reduce the half amount of CO2 by middle of this century, to stop global warming all over the world.

Many countries make plans to reduce CO2. For example, EU will reduce 20% CO2 compared with 1990. America will reduce much amount of CO2. And Japan will reduce half of CO2 by 2050. But developing countries like China and India don't make plans. So developed countries urge them to make plans soon.

Now one system is noticed. This system is discharged right of CO2. In this system, if we achieve discharged goal, we can sell the right to others. This system means that the more we reduce CO2, the more we can earn. This system is already used in EU and decided to use in America. Also Japan will use this system. This system is useful to stop global warming, also reduce cost and create economic competition. So many countries should use this system.
