Climate fight must be ethical

Climate change is a scientific and political issue. And development boundaries today are practically defined by emission limits of greenhouse gases (GHGs).

In such a situation, China has to unite the rest of the developing world and make every effort possible to steer global climate politics toward a fair and ethical foundation. This is especially important because the US always binds its GHG emission to the transparency of China's programs to fight climate change. The complicated issue presents China with three challenges.

First, carbon emissions should not be calculated by taking an entire country as a single unit. Many international authorities, including the UN's Intergovernmental Panel on Climate Change, have been analyzing global carbon emission according to national and regional emission levels.
