Desirable Per Capita GHG Emissions and Current Per Capita CO2 & GHG Emissions by Country

According to the IPCC's 'RCP 2.6' scenario for their Fifth Assessment Report (AR5) that meets the long term target of limiting the global mean temperature rise to 2 degrees Celsius (or 3.6 degrees Fahrenheit) above the pre-industrial age level (Girod et al., 2013): 
(1) in 2050, the greenhouse gas emissions per capita have to be about 2.1 metric tons of CO₂ equivalent among all the countries; and 
(2) at the end of the 21st century, the GHG emissions will have to be negative.

The following table contains country rankings by current (in 2010) CO₂ emissions per capita and greenhouse gas emissions per capita. CO₂ is just one element of UNFCCC-designated seven greenhouse gases (CO₂, N₂O, CH₄, HFCs, PFCs, SF₆, & NF₃). Because the per capita GHG emissions are always greater than the CO₂ emissions, reducing the per capita GHG emissions level down to 2.1 tonnes of CO₂ per year by 2050 seems very difficult. For example, El Salvador emitted about 2.1 tonnes of GHGs per capita in 1994.

Note:

On 'Niue' (Explanation from the GHG gas data source): 1994 is considered as an uncharacteristically high in terms of GHG emissions. It was mainly influenced by large-scale extension of Niue's international airport runway, and the major construction and sealing of roads (230 km). The high per capita figure is also due to a very small population base.
