So the global emissions trading system can be born from the bottom up.

What are we going to do about the emissions trading scheme?

I see emissions trading at this time as something of a substitute.

Emissions trading systems work very well in theory but the reality is somewhat different.

What is the emissions trading scheme and does it work?

Other options for emissions trading itself should also be studied.

Finally, looking ahead to the post 2012 emissions trading scheme, how are you going to make it work in future?

We have to use mechanisms such as the emissions trading scheme to drive the economy.

In addition, that country will be suspended from making transfers under an emissions trading program.

Developed countries may use emissions trading until late 2014 or 2015 to meet their first-round targets.
