Hailed until only months ago as a silver bullet in the fight against global warming, biofuels are now accused of snatching food out of the mouths of the poor.
Billions have been poured into developing sugar and grain-based ethanol and biodiesel to help wean rich economies from their addiction to carbon-belching fossil fuels, the overwhelming source of man-made global warming.
Heading the rush are the US, Brazil and Canada, which are eagerly transforming corn, wheat, soybeans and sugarcane into cleaner-burning fuel and the EU is to launch its own ambitious program.
But as soaring prices for staples bring more of the planet’s most vulnerable people face-to-face with starvation, the image of biofuels has suddenly changed from climate savior to a horribly misguided experiment.
On Friday, the head of the IMF said biofuels “posed a real moral problem” and called for a moratorium on using food crops to power cars, trucks and buses.
The vital problem of global warming “has to be balanced with the fact that there are people who are going to starve to death,” Dominique Strauss-Kahn said.
“Producing biofuels is a crime against humanity,” the UN’s special rapporteur for the right to food, Jean Ziegler of Switzerland, had said earlier.
Biofuels may still be in their infancy but they are growing rapidly, with annual production leaping by double-digit percentages.
In a speech on Wednesday that set down a target for reducing US carbon emissions, US President George W. Bush pointed to legislation requiring US producers to supply at least 136 billion liters of renewable fuel by 2020.
Last year, 20 percent of grain — 81 million tonnes — produced in the US was used to make ethanol, according to US think tank the Earth Policy Institute, which said the percentage will jump to nearly a quarter this year.
“We are looking at a five-fold increase in renewable fuel,” Bush’s top climate change adviser, Jim Connaughton, said in Paris on Thursday at a meeting of the world’s major greenhouse-gas polluters.
But more than half of that legislatively-mandated production would come from the “second-generation” biofuels that are made from non-food sources such as switchgrass and wood byproducts, he said.
The EU’s and the Brazilian delegates in Paris contested the link between biofuels and the world food crisis.
“This is highly exaggerated,” said Sergio Serra, Brazil’s ambassador for climate change.
“There is no real relation of cause and effect between the expansion of the production of biofuels and the raising of food prices. At least it is not happening in Brazil,” he said.
EU Environment Commissioner Stavros Dimas said experts would report back by the end of next month on how to guarantee that Europe’s planned biofuel boost would not impinge on the environment or the poor.
“There are a lot of concerns about social impacts, rising food prices and environment issues, and for all those reasons we want to insist on sustainability criteria in our legislation,” he said.
Defenders of biofuels say food shortfalls have multiple causes, including a growing appetite for meat among the burgeoning middle class in China and India.
A Chinese freighter that allegedly snapped an undersea cable linking Taiwan proper to Penghu County is suspected of being owned by a Chinese state-run company and had docked at the ports of Kaohsiung and Keelung for three months using different names. On Tuesday last week, the Togo-flagged freighter Hong Tai 58 (宏泰58號) and its Chinese crew were detained after the Taipei-Penghu No. 3 submarine cable was severed. When the Coast Guard Administration (CGA) first attempted to detain the ship on grounds of possible sabotage, its crew said the ship’s name was Hong Tai 168, although the Automatic Identification System (AIS)
An Akizuki-class destroyer last month made the first-ever solo transit of a Japan Maritime Self-Defense Force ship through the Taiwan Strait, Japanese government officials with knowledge of the matter said yesterday. The JS Akizuki carried out a north-to-south transit through the Taiwan Strait on Feb. 5 as it sailed to the South China Sea to participate in a joint exercise with US, Australian and Philippine forces that day. The Japanese destroyer JS Sazanami in September last year made the Japan Maritime Self-Defense Force’s first-ever transit through the Taiwan Strait, but it was joined by vessels from New Zealand and Australia,
SECURITY: The purpose for giving Hong Kong and Macau residents more lenient paths to permanent residency no longer applies due to China’s policies, a source said The government is considering removing an optional path to citizenship for residents from Hong Kong and Macau, and lengthening the terms for permanent residence eligibility, a source said yesterday. In a bid to prevent the Chinese Communist Party (CCP) from infiltrating Taiwan through immigration from Hong Kong and Macau, the government could amend immigration laws for residents of the territories who currently receive preferential treatment, an official familiar with the matter speaking on condition of anonymity said. The move was part of “national security-related legislative reform,” they added. Under the amendments, arrivals from the Chinese territories would have to reside in Taiwan for
CRITICAL MOVE: TSMC’s plan to invest another US$100 billion in US chipmaking would boost Taiwan’s competitive edge in the global market, the premier said The government would ensure that the most advanced chipmaking technology stays in Taiwan while assisting Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) in investing overseas, the Presidential Office said yesterday. The statement follows a joint announcement by the world’s largest contract chipmaker and US President Donald Trump on Monday that TSMC would invest an additional US$100 billion over the next four years to expand its semiconductor manufacturing operations in the US, which would include construction of three new chip fabrication plants, two advanced packaging facilities, and a research and development center. The government knew about the deal in advance and would assist, Presidential
