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.
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.
