The number of households projected to use charcoal as an energy source in Cambodia will rise to more than 1 million in 2015 from about 500,000 now, according to a 2008 study conducted jointly by Cambodia’s Ministry of Industry, Mines and Energy, the United Nations Development Program and the environmental group Geres.
That projected increase has raised concerns among environmentalists, who note that charcoal production entails the removal of vast quantities of woodland, often in naturally growing forests, as well as high levels of “black carbon” or soot — which scientists say plays a significant role in global warming.
The report values the current annual market for charcoal in the capital, Phnom Penh, at $25 million — a number that is expected to more than double during the next five years based on current trends.
And while the authors note a shift toward modern energy sources, they reported that “the demand for firewood, charcoal, kerosene and batteries will remain high over the next decades.”
Wood burners for cooking, which are used extensively in Asia and Africa, produce large quantities of soot particles, which scientists say are responsible for as much as 18 percent of global warming.
David Beritault, an energy expert at Geres, said much of the charcoal made in Cambodia had not been sufficiently burned to complete its transformation from wood, a phenomenon that leads to higher levels of black carbon in the atmosphere. Black carbon can travel long distances, warming the air and melting ice by absorbing the sun’s heat.
But charcoal, if produced correctly, can burn almost smokeless and is less polluting than wood — although it does emit greenhouse gases during its production. Geres is involved in a so-called green charcoal project that aims to make the material with more energy-efficient wood.
“If we can control the process, we can produce the same amount of charcoal but with less wood,” Mr Beritault said.
Environmentalists also say that water filters, which cost about $7.50, could be used instead of having to boil water to make it potable. Moreover, Biodigesters, which provide a cheap source of fuel by converting organic waste into biogas, are another option that could improve health conditions in households that cook with wood and charcoal.
Still, 27 percent of residents in Phnom Penh use charcoal as their main energy source, according to the Ministry of Industry, and urban demand for charcoal is expected to nearly triple over the next two decades.
Khiev Thim, a charcoal merchant in the Phnom Penh who, on a recent morning, sold roughly 1,300 pounds of charcoal to a variety of households and small businesses, said demand in the city was fierce.
“We sell it everywhere in the city,” he said, “except along the main roads.”

If the CPP cronies go into this market, you can kiss the remaining forests good bye.
China and the US use about 85% of all world coal, it is also pointless to speak about Cambodia's coal contribution to Global Warming.
