Gross carbon dioxide emissions from coal usage are slightly more than those from petroleum and about double the amount from natural gas.

One of the aims of this program is the goal of optimising coal usage to, amongst other things, accelerate development in the producing regions of Indonesia.

In 1999 world gross carbon dioxide emissions from coal usage were 8,666 million tonnes of carbon dioxide.

To a first approximation, the total emissions from oil and gas is fixed, and the total load of carbon in the atmosphere is determined by coal usage.

Between 2025 and 2050 it is assumed that both developed and developing countries will linearly phase out emissions of CO from coal usage.

In 2012 The German electricity sector increased its coal usage by 4.9 percent over its coal consumption value of 2011.

This increase in coal usage was largely due to a power gap in Germany created after the nation shutdown 8 of its 17 nuclear power plants.

Higher steam engine efficiency caused the number of steam engines to increase several fold, leading to an increase in coal usage, the phenomenon being called the Jevons paradox.

And it is unlikely that we will turn the clock back anywhere since China are ramping up their coal usage.

Future coal usage is highly dependent on legislative drivers on emissions and the need to have security of supply.
