IEA finds CO2 emissions flat for third straight year even as global economy grew in 2016

Green Car Congress

Global energy-related carbon dioxide emissions were flat for a third straight year in 2016 even as the global economy grew, according to the International Energy Agency. The biggest drop came from the United States, where carbon dioxide emissions fell 3%, or 160 million tonnes, while the economy grew by 1.6%.

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.

Carbon emissions associated with increased exports from China (left), as part of a more systematic view of increased national emissions (right), 2002 to 2005. Researchers from Norway, the United Kingdom, and the United States, estimated in the study that China’s 2005 carbon emissions were 80.59% or more higher than 2002 emissions. “

In addition, global carbon dioxide emissions have been increasing. The past decade was the first in two centuries with increasing CO2 emissions intensities, owing to a “coal revival”, in contrast with the rapid conversion to natural gas in the 1990s.

Shown are fossil CO2 emissions (top panel) and corresponding global warming (bottom panel). The researchers, involving scientists from Germany, the United Kingdom and Switzerland, concluded that the limit is 1,000 billion tonnes of carbon dioxide between the years 2000 and 2050.

IEA World Energy Outlook view on the transport sector to 2035; passenger car fleet doubling to almost 1.7B units, driving oil demand up to 99 mb/d; reconfirming the end of cheap oil

Green Car Congress

Without a bold change of policy direction, the IEA warned at the launch, the world will lock itself into an insecure, inefficient and high-carbon energy system. The use of coal—which met almost half of the increase in global energy demand over the last decade—rises 65% by 2035. Other Findings from WEO 2011.
