5. No reduction in fossil fuel share of
world energy mix
‘ Fossil fuels still account for most – over 80% – of the world energy supply.
Since 1870, CO2 emissions from fuel combustion have risen exponentially.
The 2012 concentration of CO2 (394 ppmv) was about 40% higher than in the mid1800s, with an average growth of 2 ppmv/year in the last ten years.
Significant increases have also occurred in levels of methane (CH4) and nitrous oxide
(N2O).
Despite the growth of non-fossil energy (such as nuclear and hydropower), considered
as non-emitting, the share of fossil fuels within the world energy supply is relatively
unchanged over the past 40 years.
In 2011, fossil sources accounted for 82% of the global energy supply.’

11. Fossil-fuel subsidies increased to $544 billion in 2012
Estimates of ultimately recoverable resources of oil continue to increase as technologies unlock
types of resources, such as light tight oil, that were not considered recoverable only a few
years ago.
Our latest estimates for remaining recoverable resources show 2 670 billion barrels of
conventional oil (including NGLs), 345 billion of light tight oil, 1 880 billion of extra-heavy oil
and bitumen, and 1 070 billion of kerogen oil.
Fossil fuels continue to dominate the power sector, although their share of
generation declines from 68% in 2011 to 57% in 2035.
Coal remains the largest source of generation

19. CO2 emissions from the power sector rise from
13.0 gigatonnes (Gt) in 2011 to
15.2 Gt in 2035,
retaining a share of around 40% of global emissions
over the period.
