CO2 Now

The 2014 average annual concentration of CO2 in the atmosphere (Mauna Loa Observatory) is 398.55 parts per million (ppm).   The 2013 average is 396.48 ppm.  

For the past decade (2005-2014) the average annual increase is 2.1 ppm per year.  The average for the prior decade (1995-2004) is 1.9 ppm per year.    Annual data for 2014 was first posted January 6, 2015, by NOAA-ESRL in the United States. 

Since the 1958 start of high-precision instrument measurements of CO2 in the atmosphere, the annual mean concentration of CO2 has only increased from one year to the next.   The CO2 data below provide a simple view of the annual trend. 

The world's most current data for atmospheric CO2 is measured at the Mauna Loa Observatoy in Hawaii.  Measurements are made and reported independently by two scientific institutions:  Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA).  Monthly data is posted below.   

Mauna Loa CO2 Data Sets:

    Monthly     NOAA CO2 Data
    Weekly        NOAA CO2 Data

    Monthly    Scripps CO2 Data
    Daily           Scripps CO2 Data

Atmospheric CO2 is accelerating upward from decade to decade.   

For the past ten years (2005 - 2014), the average annual rate of increase is 2.11 parts per million (ppm).   This rate of increase is more than double the increase in the 1960s.

Global CO2 Budget 2014

GlobalCarbonProject.org 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.
