This past fall, Obama and President Xi Jinping finally came
to a climate change agreement: China’s carbon emissions will peak around 2030
and the United States will cut carbon emissions by at least 26% from 2005
levels by 2025. As China and the United States are the two biggest carbon
emitters in the world right now, this is an important agreement. However, are
their goals enough to keep the global temperature from rising more than 2
degrees Celsius?
Many scientists believe that waiting until 2030 for China’s
emissions to peak may be too late if we are to keep global warming from rising
above the 2°C limit. Instead, China should try to peak their emissions by
2025. Based on the huge coal consumption numbers in China, some leaders are
working on cutting back the country’s dependence on coal. Not only would this
reduce greenhouse gas emissions, but it would also help rid China of the toxic
smog surrounding the country’s cities.

In addition to halting the growth of its emissions, China
agreed to make 20% of its energy renewable by 2030. Chinese officials have been
looking into wind, solar, and hydroelectric, and nuclear power as possible
alternatives to coal. 9.8% of China’s energy came from renewable energy sources
in 2013, so it seems probable that it will reach 20% by 2030.
While China still has a long way to go towards
sustainability, the fact that the largest source of greenhouse gas emissions in
the world has pledged to at least do something in regards to its tremendous
pollution is significant.
