Presidents Barack Obama and Xi Jinping declare that the U.S and China will cut greenhouse gas emissions by 2020
|Presidents Barack Obama and Xi Jinping |
shake hands and ratify the Paris Agreement
The two largest emitters of greenhouse gases in the world are the U.S. and China. In a historic move, both countries ratified the Paris Agreement to set the stage for the annual G20 summit. American President Barack Obama and Chinese President Xi Jinping happily struck the climate deal despite recent military and political tension in the South China Sea. While the Paris Agreement was only written less than a year ago, it has tremendous implications for climate change. Ratification of the Paris Agreement serves as a country's promise to a United Nations committee to mitigate greenhouse gas emissions by a certain amount by 2020.
As seen in the figure below, China has been the world's largest emitter of carbon-based pollutants since around 2004. Due to efforts in recent years, China has maintained roughly the same level of emissions since around 2010. This recent history sets the precedent for China's ratification of the G20 summit. China's government is pushing the public policy of 负责任大国 (fu zeren daguo) a great nation takes responsibility) when it concerns itself with climate change. It does so not only in the name of international pressure but in order to protect its own citizens from environmental problems.

This ratification could influence other G20 nations to agree to the Paris dealThe leadership demonstrated by China and America should be instrumental in influencing other nations to ratify. As other countries witness the two largest emitters of greenhouse gases sign the Paris agreement, they will feel pressure to do the same. India has recently been making plans to ratify. This is expected to happen within the next month, according to BBC news. This would be a monumental success for the Paris Agreement since the three largest emitters of greenhouse gases would have agreed to reduce emissions.
Many believe ratification to be a step in the right direction. With that knowledge, it is no surprise that mitigation of greenhouse gases is a major motivator of change in politics and industry. With the two largest national emitters of greenhouse gases ratifying the agreement, the other countries in the G20 are expected to follow suit.
