Countries around the world have increasingly become aware of the challenges of climate change and global warming. The Intergovernmental Panel on Climate Change (IPCC) has provided clear scientific evidence that the concentration of greenhouse gases, such as carbon dioxide (CO2), is much higher today than ever before in the last 600,000 years (see Exhibit 12.1). As a conclusion, IPCC estimates that the level of global CO2-emissions needs to be reduced by 80% before 2050 in order to avoid dangerous changes in the earth’s atmosphere.
