Rapid urbanization, industrialization and intensive agriculture have made BRICS countries particularly vulnerable to the effects of global warming. As important economies in the world, their actions will severely influence the result of GHGs emission reduction world-wide. China is facing double pressure of energy shortage domestically and green-house gases (GHGs) emission reduction internationally in the climate change era. China has enacted several laws and regulations regarding to energy saving and renewable energy, and is making Energy Law of PRC. These laws and regulations have played important role in dealing with energy saving and GHGs emission reduction, but there still exist some defects and can’t deal with climate change issues well. Studying the energy laws and policies in BRICS countries together will provide experiences and guidance for China to reconstruct its energy laws and regulations from the dimension of international cooperation especially with BRICS countries. China as a developing country should coordinate its stance and policy in energy sector and climate change international negotiation.
