Summary

Carbon dioxide (CO2) emissions from fossil fuel burning and cement production increased by 2.1% in 2012, with a total of 9.7±0.5 GtC (billion tonnes of carbon) emitted to the atmosphere, 58% above 1990 emissions (the Kyoto Protocol reference year). Emissions are projected to increase by a further 2.1% in 2013.  In  2012, the ocean and land carbon sinks respectively removed 28% and 23% of total (fossil fuel and land use change) CO2. The land sink in 2012 was much less than in 2011, a year of a strong La Niña weather pattern. Read more ...

coal mine Emissions from fossil fuels and cement

Carbon dioxide (CO2) emissions from fossil fuel burning and cement production increased by 2.1% in 2012, with a total of 9.7±0.5 GtC emitted to the atmosphere. These emissions were the highest in human history and 58% higher than in 1990 (the Kyoto Protocol reference year). In 2012, coal burning was responsible for 43% of the total emissions, oil 33%, gas 18%, cement 5.3%, and gas flaring 0.6%. Emissions are projected to increase by 2.1% in 2013, to a record high of 9.9±0.5 GtC (36 billion tonnes of CO2), 61% above emissions in 1990. Read more ...

Regional fossil fuel emissions
In 2012, global CO2 emissions were dominated by emission from China (27%), the USA (14%), the EU (28 member states; 10%) and India (6%). Growth rates of these countries from 2011 to 2012 were 5.9% for China, −3.7% for the USA, −1.3% for the EU28, and 7.7% for India. The per-capita CO2 emissions in 2012 were 1.4 tC person-1 yr-1 for the globe, and 4.4, 1.9, 1.9 and 0.5 tonnes of C person-1 yr-1 for the USA, the EU, China, and India, respectively. Read more ...

Consumption-based fossil fuel emissions
Consumption-based emissions allocate emissions to where goods and services are consumed, not where they are produced and emissions released. Territorial-based emissions in Annex B (developed countries) countries remained stable from 1990-2011, while consumption-based emissions grew at 0.5% yr-1. In non-Annex B countries, territorial- and consumption-based emissions grew at 4.3% yr-1 and 4.0% yr-1, respectively. Read more ...

Emissions from land use change
CO2 emissions from deforestation and other land use change were 0.9±0.5 GtC on average during 2003-2012, accounting for about 8% of all emissions from human activity (fossil fuel, cement, land use change). The data suggest an overall decrease trend in land-use change emissions particularly since 2000. Emissions were 1.4±0.5 GtC yr-1 during the decade of 1990s. Read more ...

Emission pathways
Current trajectories of fossil fuel emissions are tracking some of the most carbon intensive emission scenarios used in the Intergovernmental Panel on Climate Change (IPCC). The current trajectory is tracking the Representative Concentration Pathway 8.5 (of the latest family of IPCC scenarios) that takes the planet's average temperature to about 3.2°C to 5.4°C above pre-industrial times by 2100.

CO2 removals by natural sinks
Of the total emissions from human activities during the period 2003-2012, about 45% accumulated in the atmosphere, 27% in the ocean and 27% on land. During this period, the size of the natural sinks has grown in response to the increasing emissions, although year-to-year variability of that growth is large. Read more ...

Atmospheric CO2
The annual growth rate of atmospheric CO2 was 5.2±0.2 GtC in 2012, corresponding to an increase of 2.43±0.09 parts per million in the atmospheric concentration. This is significantly above the 2003-2012 average of 4.3±0.1 GtC yr-1, thought the interannual variability in atmospheric growth rate is large. The global atmospheric CO2 concentration reached 392.52±0.10 ppm on average over 2012. Read more ...
