China's plans for global warming

I think that China has the right idea in making plans to lessen global warming especially since experts say that China will soon pass the U.S. and become the leading country for greenhouse gas emissions. What I don't understand is why all of these countries are making plans for the later years and not trying to make the change now. Now is when we need to make the changes, not 10 years from now, because 10 years from now might be too late.
