Global CO2 emissions stalled for the third year in a row

The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO2 emissions have stalled for the third year in a row.

The report provides updated results on the continuous monitoring of the three main greenhouse gases: carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

Global GHG emissions continue to be dominated by fossil carbon dioxide (CO2) emissions, which however show a slowdown trend since 2012, and were stalled for the third year in a row in 2016.

Russia, China, the US and Japan further decreased their CO2 emissions from 2015 to 2016, while the EU's emissions remained stable with respect to the previous year, and India's emissions continued to increase.

Other greenhouse gases keep creeping up
Information on the other two greenhouse gases, methane (CH4) and nitrous oxide (N2O), is only available until 2012, as international statistics on agricultural activities - the main source of these emissions - are not updated as frequently as on energy and industry-related activities.

Uncertainty is also higher for these emissions than for CO2 emissions.

However, the data until 2012 shows a steady increase in global GHG emissions, with an overall increase of 91% from 1970 to 2012.

CH4 is mainly generated by agricultural activities, the production of coal and gas, as well as waste treatment and disposal. N2O is mainly emitted by agricultural soil activities and chemical production.

In the EU, 60% of the CH4 and N2O emissions are emitted by the top six emitting countries - Germany, UK, France, Poland, Italy and Spain.

The upward trend in CH4 and N2O emissions is also visible in the US, China, Japan and India which all recorded increasing GHG emissions.

Europe's downward trend stalling
Over the past two decades, the EU28 has steadily decreased its CO2 emissions, which still represent two thirds of the EU's total greenhouse gas emissions.

In 2016, the EU's CO2 emissions were 20.8% below the levels in 1990 and 17.9% below the levels in 2005. Since 2015, the EU's CO2 emissions have stabilised, representing 9.6% of global emissions.

Country profiles
The report is based on the JRC's Emissions Database for Global Atmospheric Research (EDGAR), which is not only unique in its space and time coverage, but also in its completeness and consistency of the emissions compilations for multiple pollutants: the greenhouse gases (GHG), air pollutants and aerosols.

The new report contains country-specific fact sheets for 216 countries. The factsheets show the evolution of country-level CO2 emissions from 1990 to 2016 and the evolution of country-level GHG emissions from 1970 to 2012.

New Insights From OCO-2 Showcased in Science
Pasadena CA (JPL) Oct 16, 2017
High-resolution satellite data from NASA's Orbiting Carbon Observatory-2 are revealing the subtle ways that carbon links everything on Earth - the ocean, land, atmosphere, terrestrial ecosystems and human activities. Scientists using the first 2 1/2 years of OCO-2 data have published a special collection of five papers today in the journal Science that demonstrates the breadth of this research. ... read more
