Yes, China has to definitely sign up to the emission-reduction targets. With increase in the consumption level of energy, where the emission becomes hazardous to the environment, developing countries like China to should take part in the emission-reduction programmes and make a better future to the young and future generations. A good infrastructure and good environment will definitely increase the productivity and economy of the people in a country. I think by the end of 21st century, China should have implemented the emission-reduction techniques to keep the people and economy safe.
