The Working Group III contribution to the Intergovernmental Panel on Climate Change Fifth Assessment Report (Climate Change 2014: Mitigation of Climate Change) is now released.
The following figure is very important because it gives the most authoritative time-series information about gas-by-gas global greenhouse gas emissions. Other global emissions estimates (by GCP, IEA, BP, EDGAR, & US EIA) are limited to CO2. CO2 is, although it accounted for 76% (65% from combustion + 11% from land use) of the total GHG emissions in 2010, just one of seven UN-designated greenhouse gas groups (CO2, N2O, CH4, HFCs, PFCs, SF6, & NF3).
When I get the actual (detailed) numbers for the graph, I'll update this post.
Figure. Total Annual Anthropogenic Greenhouse Gas Emissions by Groups of Gases 1970-2010
CO2 FOLU = CO2 emissions from Forestry and Other Land Use
F-gases = Fluorinated gases covered under the Kyoto Protocol
At the right side of the figure: Emissions of each greenhouse gas with associated error bars (90% confidence interval)
