8 gigatonne of oil equivalent (Gtoe), according to Gas Exporting Countries Forum (GECF).
8 gigatonne of oil equivalent (Gtoe), and by 2040, fossil fuels are expected to meet 75 percent of the world's energy demand.
5 billion barrels of oil equivalent (2015-2030), leading to overall savings of USD 55 billion to USD 87 billion and a reduction of carbon emissions around 1 gigatonne (Gt) by 2030, resulting in an 8% reduction in the region's per capita carbon footprint.
Government of Norway in 2014, recently found that implementing renewable energy and energy efficiency projects in developing countries from 2005 to 2015 will lead to a half gigatonne reduction in emissions by 2020.
One gigatonne is roughly equivalent to the emissions generated by transport in the European Union (including aviation) over a year.
But the Unep report finds that, on current trends, emissions are set to reach the equivalent of 54-56 gigatonnes (billion tonnes) of carbon dioxide by the end of the next decade - well above the 42 gigatonne maximum if warming is to be kept below 2degC.

One gigatonne of carbon corresponds to: 1E12 kg divided by 0.
The report said that the 90 companies on the list of top emitters produced 63 percent of the cumulative global emissions of industrial carbon dioxide and methane between 1751 and 2010, amounting to about 914 gigatonne CO2 emissions.
However, rapid action to cap and cut HFC emissions by 4 per cent annually, along with fostering readily available alternatives, could see them fall to under one gigatonne by 2050.
