Global CO2 Emissions Reach All-Time High, Rising More Than 5% in
2010 to Close Out Past 20 Years

Global
carbon
dioxide (CO2) emissions reached an all-time high in
2010, rising 45% in the past 20 years. Rising rapidly between 1990 and
2010, global atmospheric CO2 levels totaled 33 billion metric tons last
year, according to a report published by the European Commission’s
Joint
Research
Center and PBL Netherlands Environmental Assessment
Agency. Global CO2 emissions fell 1% in 2009, during the Great
Recession, but rose at an unprecedented 5% rate in 2010. That was
similar to the drop and greater emissions growth in 1975 and 1976, when
the global economy suffered through the first oil crisis, a subsequent
stock
market crash and began a recovery in 1976, the report
authors note.
Emissions Growth Greatest in Rapidly Industrializing
Countries
Total CO2 emissions in industrialized nations that ratified the Kyoto
Protocol and the US, which didn’t, were some 7.5% less in 2010 than they
were in 1990, leaving them on-track to meet the 5.2% reduction targets
required by the climate treaty.
Industrialized nations’ share of global CO2 emissions has been dropping.
Rapid industrialization in large emerging market economies, such as
China, India and Brazil, led to industrialized countries overall
contribution to global CO2 emissions dropping to less than half the
total amount from two-thirds over the two decade period.
Since 1990, CO2 emissions per capita have increased in China from 2.2 to
6.8 metric tons per capita and decreased in the EU-27 from 9.2 to 8.1
metric tons per capita (in EU-15 from 9.1 to 7.9) and from 19.7 to 16.9
metric tons per capita in the USA, according to the report.
CO2 emissions rose in most of the world’s major economies despite the
slow and sputtering economic recovery of the past two-plus years.
Emissions increases were greatest in China (10%) and India (9%). They
increased four percent in the US and 3% in the 27-member European Union
(EU).
Man-Made Emissions
Measuring “non-biogenic,” or man-made CO2 emissions, the agency
researchers estimated that man-made emissions totaled 22.7 billion
metric tons in 1990 and 31.6 billion metric tons in 2008. A first
estimate puts the 2010 total at 33 billion metric tons, an increase of
45% in the past 20 years. That’s the same as were emitted in the prior
20-year period, according to the researchers. The non-biogenic total
excludes emissions from biomass burning, such as forest fires, for which
attribution of cause is uncertain.
The preliminary estimates of non-biogenic emissions were based on energy
consumption data for 2008 to 2010 recently published by BP, estimates
based on production of cement, lime, ammonia and steel, and emissions
per country from 1970-2008 from version 4.2 of the
Emissions Database for Global Atmospheric Research (EDGAR), a joint
PBL-JRC project.
