Alaska: An Energy and Economic Analysis - IER

26/08/2013  Carbon dioxide, the largest occurring greenhouse gas, is a natural byproduct of the combustion of all carbon-containing fuels, such as natural gas, petroleum, coal, wood, and other organic materials, including biofuels. Today, there is no cost-effective way to capture the carbon dioxide output of the combustion of these fuels, so any regulations that limit carbon dioxide emissions will either ...

28/07/2008  Carbon dioxide (CO 2) emissions from combusting fossil fuels are the main driver of global warming. CO 2 is also the main byproduct of coal combustion: nearly 4 grams of CO2 are produced for every gram of carbon burnt (depending on its type, coal can contain as much as 60 to 80 percent carbon). Methane (CH4) often occurs in the same areas that coal is formed, and is released
