The Cause of increasing GHGs concentration o. necessary to restrain the increase of temperature within 2 ℃ for minimizing the effect by climate change - 1, 000 Gt CO 2 eq. as permissible total GHGs emission amounts until 2, 100 - already 531 Gt CO 2 emitted till 2011 - permissible GHGs emission amounts to emit until 2, 100; 470 Gt CO 2
