CO2 Now


What the world needs to watch

Global warming is mainly the result of CO2 levels rising in the Earth’s atmosphere. Both atmospheric CO2 and climate change are accelerating. Climate scientists say we have years, not decades, to stabilize CO2 and other greenhouse gases.

To help the world succeed, makes it easy to see the most current CO2 level and what it means. So, use this site and keep an eye on CO2.  Invite others to do the same. Then we can do more to send CO2 in the right direction.

Watch CO2 now and know the score on global warming, practically in real time.

Global Carbon Budget 2010

Global CO2 Budget 2014 posted data for the 2014 Global Carbon Budget on September 21, 2014.  Some key findings are set out below:

*In 2013, global CO2 emissions due to fossil fuel use (and cement production) were 36 gigatonnes (GtCO2); this is 61% higher than 1990 (the Kyoto Protocol reference year) and 2.3% higher than 2012.

*In 2014, global CO2 emissions are projected to increase by an additional 2.5% over the 2013 level.  

*CO2 emissions were dominated by China (28%), the USA (14%), the EU (10%), and India (7%)--with growth in all of these states except for a 1.8% decline in the EU (28 member states). 

*The 2013 carbon dioxide emissions (fossil fuel and cement production only) breakdown is: coal (43%), oil (33%), gas (18%), cement (5.5%) and gas flaring (0.6%).

*Emissions from land use change accounts for 8% of total CO2 emissions; the data suggests an overall decreasing trend in land use change emissions particularly since 2000.

Carbon Emissions 


9.9 billion metric tonnes (GtC)


9.7 billion metric tonnes (GtC)


9.47 billion metric tonnes (GtC)


9.19 billion metric tonnes (GtC)


8.74 billion metric tonnes (GtC) 


8.77 billion of metric tonnes (GtC) 


8.57 billion metric tonnes (GtC)


8.37 billion metric tonnes (GtC)


To convert carbon to carbon dioxide (CO2), multiply the numbers above by 3.67.  

NY Times  |  Carbon emissions show biggest jump ever recorded  |  December 2011
The increase, a half-billion extra tons of carbon pumped into the air, was almost certainly the largest absolute jump in any year since the Industrial Revolution, and the largest percentage increase since 2003. 

Science Daily  |  Global CO2 emissions may reach record levels in 2010
Global carbon dioxide (CO2) emissions -- the main contributor to global warming -- show no sign of abating and may reach record levels in 2010, according to a study led by the University of Exeter (UK).

About the Global Carbon Project

The Global Carbon Project is produced by the Earth System Science Partnership (ESSP).  The ESSP is a partnership for integrating the study of the Earth system, the ways it is changing and the implications for global and regional sustainability.  The 2008 Global Carbon Budget is produced by the Global Carbon Project with:

·         the United Nations Educational, Scientific and Cultural Organization (UNESCO),

·         the Scientific Committee on Problems of the Environment (SCOPE), and

·         the United Nations Environment Programme (UNEP).

Scientific Prediction of Global Carbon Emissions:

The current growth in global anthropogenic CO2 emissions is tightly linked to the growth in GDP. On the basis of the projected changes in GDP, it is likely that CO2 emissions in 2009 will revert to their 2007 levels. The key to sustained emissions reductions after the global economy recovers lies in restructuring the primary energy use to decouple emissions from GDP.
