Climate change has being brought disaster to all humankind,while low-carbon development has been necessary and urgent. This paper analyzed the development measures of low-carbon economy taken by developed and developing countries,and proved that China has made great efforts on energy conservation,emission reduction, and development of low-carbon economy.According to the article,it is a reasonable way to solve climate change problem that we should adhere to the principles of common but differentiated responsibilities and the responsibility of states assigned by cumulative emissions per capita. Because of some practical reasons in home and abroad, our country must take low-carbon development road,although there are many constraints of low-carbon economy development in China. This paper put forward a lot of suggestion on China's development of low-carbon economy, and emphasized proper "development philosophy"  as the guide to meet the challenges of low-carbon development.
