Fossil fuel combustion accounts for about 90% of total global CO2 emissions, excluding those from forest fires and the use of wood fuel (EDGAR 4.2, JRC/PBL, 2011).
As the global economy continued to grow (3.5%) in most countries in 2012, global energy consumption saw an actual growth of 1.5% (1.2% after leap year correction), which represents half the average growth over the last decade (BP, 2013; NBSC, 2013).
The CO2 emission trends in OECD and non-OECD countries are diverging, with a 1.4% decline in OECD countries, the fifth decrease in the past seven years, versus a 2.7% increase in non-OECD countries.
