Global Carbon Emissions

Global Carbon Emissions

Global carbon (C) emissions from fossil fuel use were 9.795 gigatonnes (Gt) in 2014 (or 35.9 GtCO₂ of carbon dioxide).  Fossil fuel emissions were 0.6% above emissions in 2013 and 60% above emissions in 1990 (the reference year in the Kyoto Protocol).
Based on a 2015 GDP forecast of 3.1% by the International Monetary Fund, the Global Carbon Project projects a 2015 decline of 0.6% in global emissions.

Human Sources

Fossil fuel emissions (including cement production) accounted for about 91% of total CO₂ emissions from human sources in 2014. This portion of emissions originates from coal (42%), oil (33%), gas (19%), cement (6%) and gas flaring (1%).
Changes in land use are responsible for about 9% of all global CO₂ emissions.
In 2013, the largest national contributions to the net growth in total global emissions in 2013 were China (58% of the growth), USA (20% of the growth), India (17% of the growth), and EU28 (a decrease by 11% of the growth).

Natural Sinks

For the decade from 2005 to 2014, about 44% of CO2 emissions accumulated in the atmosphere, 26% in the ocean, and 30% on land.

Cumulative Emisions

From 1870 to 2014, cumulative carbon emissions totaled about 545 GtC.  Emissions were partitioned among the atmosphere (approx. 230 GtC or 42%), ocean (approx. 155 GtC or 28%) and the land (approx. 160 GtC or 29%).

Atmospheric Accumulation

The 2014 level of CO2 in the atmospheric was 43% above the level when the Industrial Revolution started in 1750.
