AMSTERDAM, Netherlands -- Once, palm oil was seen as an ideal biofuel, a cheap alternative to petroleum that would fight global warming. But second thoughts are wracking the power industry. Can the fruit of the palm tree help save the planet -- or contribute to its destruction?
Environmentalists have long warned that many plantations in Indonesia and Malaysia, where 85 percent of commercial palm oil is grown, were planted on cleared rain forest, threatening the home of endangered animals like the orangutan and the Sumatran tiger. Now, amid global efforts to curb emissions of greenhouse gases, power companies have joined conservationists in calculating the carbon count of producing palm oil fuel -- and found the balance increasingly negative. A few companies have put plans on hold to switch to palm oil.
A report late last year by a Netherlands-based research group claimed some plantations produce far more carbon dioxide than they save. Seeded on drained peat swamps, they unleash a warehouse of carbon from decomposed plants and animals that had been locked in the bogs for hundreds of million years, which one biologist described as "buried sunshine." "As a biofuel, it's a failure," said Marcel Silvius, a climate change expert for Wetlands International, the institute that led the research team.
The palm oil debate is just one example of cold realism dampening enthusiasm for vegetable oils as substitutes for the fossil fuels that are widely blamed for the gradual warming of the Earth and potentially disastrous changes in climate.
