Is the oil-palm industry using global warming to mislead the public?
(11/23/2007) Members of the Indonesian Palm Oil Commission are distributing materials that misrepresent the carbon balance of oil-palm plantations, according to accounts from people who have seen presentations by commission members. These officials are apparently arguing that oil-palm plantations store and sequester many times the amount of CO2 as natural forests, and therefore that converting forests for plantations is the best way to fight climate change. In making such claims, these Indonesian representatives evidently are ignoring data that show the opposite, putting the credibility of the oil-palm industry at risk, and undermining efforts to slow deforestation and rein in greenhouse gas emissions.

Planned logging of Woodlark Island for biofuels opposed by islanders and scientists
(11/12/2007) On Woodlark Island, one-hundred and seventy miles from Papua New Guinea, a struggle is occurring between islanders and biofuel company Vitroplant Ltd. The company is planning to clear much of the island's forest for oil palm plantations to produce biofuels. Vitorplant Ltd.'s contract specifies that they would deforest 60,000 hectares of land for plantations; Woodlark Island is 85,000 hectares in total, meaning over 70% of the island would be converted. Last week, one hundred islanders (out of a total population of 6,000) traveled to the capital of Milne Bay Province, Alotau, to voice their concern over the plans to turn their forested island into plantations.
Greenwashing the palm oil industry

Oil palm does not store more carbon than forests
(11/08/2007) Officials from the Indonesian ministry of agriculture and the palm oil industry are distributing materials that misrepresent the carbon balance oil palm plantations, according to accounts from people who have seen presentations by members of the Indonesian Palm Oil Commission. Ministry of agricultural officials are apparently arguing that oil palm plantations store and sequester many times the amount of CO2 as natural forests and therefore converting forests for plantations is the best way to fight climate change. In making such claims, these Indonesian officials are ignoring data that show the opposite, putting the credibility of the oil palm industry at risk, and undermining efforts to slow deforestation and reign in greenhouse gas emissions.
Carbon-negative bioenergy to cut global warming could drive deforestation

China's coal pollutes the U.S.
(11/04/2007) It takes five to 10 days for the pollution from China's coal-fired plants to make its way to the United States, like a slow-moving storm. It shows up as mercury in the bass and trout caught in Oregon's Willamette River. It increases cloud cover and raises ozone levels. And along the way, it contributes to acid rain in Japan and South Korea and health problems everywhere from Taiyuan to the United States. This is the dark side of the world's growing use of coal.

Guidelines to ensure biofuels production won't hurt the environment
(08/30/2007) Environmentalists have long seen biofuels as a means to improve the sustainability of transportation and energy use since they are a renewable source of energy that can be replenished on an ongoing basis. Further, because biofuels are generally derived from plants, which absorb carbon from the atmosphere as they grow, biofuel production offers the potential to help offset carbon dioxide emissions and mitigate climate change. Nonetheless, in recent years, there has been considerable backlash against biofuels, which are increasingly viewed as a threat to the environment. Green groups now point to large-scale land conversion for energy crops, higher food prices, and a spate to studies that suggest net emissions from corn ethanol are little better than those from fossil fuels, to caution that biofuels can cause more problems than they address.

Economics of next generation biofuels
(08/08/2007) 'Second generation' biorefineries -- those making biofuel from lignocellulosic feedstocks like straw, grasses and wood -- have long been touted as the successor to today's grain ethanol plants, but until now the technology has been considered too expensive to compete. However, recent increases in grain prices mean that production costs are now similar for grain ethanol and second generation biofuels, according to a paper published in the first edition of Biofuels, Bioproducts & Biorefining.
100 years ago: oil shortages spur need for alternative fuels
(08/08/2007) The fuels committee of the Motor Union of Great Britain and Ireland has issued a valuable report on motor-car fuels... a famine in petrol appears to be inevitable in the near future, owing to the fact that demand is increasing at a rate much greater than the rate of increase of the supply. In 1904 the consumption of petrol in the United Kingdom was 12,000,000 gallons; in 1907 it had risen to 27,000,000 gallons... the committee discusses in the report other possible fuels. The supply is divided into two parts. The first includes all fuels limited in quantity...The second group contains one item only - alcohol - and it is evident from the whole tone of the report that the committee expects to find in denatured vegetable spirits the fuel of the future.
