Key message 1: “Low carbon economy (LCE) is necessary to stabilize climate change.”
The first great step to prevent global warming was taken by Kyoto Protocol which came into effect on Feb.16, 2005. But it is necessary to reduce GHG (Greenhouse gases) emissions drastically to stabilize climate change. According to recent research studies, global GHG reduction target in 2050 is likely to be 50% of 1990 level so as not to exceed 2 degree global mean temperature increase from pre-industrial level. It means that reduction rate for developed countries will be more than 50%, such as 60-80%.
