Mitigating climate change — key message 6

SOER 2010 Message (Deprecated) Published 28 Nov 2010
Scientific studies show that global greenhouse gas emissions should not exceed 44 to 46 Gt CO2-equivalents per year by 2020 in order to give a 50 % chance of limiting global mean temperature increase to 2°C above pre-industrial levels. The reduction pledges made under the 2009 Copenhagen Accord fall short of keeping global greenhouse gas emissions below this peak level.
