01. Trends in CO2 Emissions and Sinks

Current and Future Trends in CO2 Emissions and Sinks

Monday 26 March 2012 - State of the Planet, 14:00

Room 12

Chaired by Corinne Le Quere, Joseph G. Canadell, Philippe Ciais

Convenors: Corinne Le Quere, Tyndall Centre for Climate Change Research; Joseph G. Canadell, Global Carbon Project and CSIRO; Philippe Ciais, Laboratoire des Sciences du Climat et de l`Environnement

CO2 emissions from fossil fuel combustion have accelerated in the past two decades, while there is evidence of decreasing emissions from deforestation and other land use activities, and debate around the efficiency of the natural carbon sinks to absorb CO2. This session will present the latest trends and underlying drivers, and discuss their persistence and consequences for the future.
