Canada, who does not like USA, decided to go out from Kyoto agreement about global warming. Japan has not gone out though everyone knows Japan cannot reach the target. Top two emission countries, USA and China, may never join. None can complain to Canada. Canada continues to reduce CO2 emission so this is not very big impact. Real impact would be new agreement will start from 2020, 9 year later. We still do not know if USA, China, India and other BRICs countries. It is very good idea to stop this discussion and share technology for CO2 reduction.
