The nations of the OECD—the Organization for Economic Cooperation and Development, who account for 56% of the planet’s energy consumption, are desperately in need of a liquid fuel replacement for oil. Worldwide petroleum extraction rates are expected to peak this year, and global supply will likely dwindle significantly in the next fifty years. There is also a great need to find substitutes for fossil fuels, which are one of the major contributors to global climate change through the emission of CO2 and other greenhouse gases.
Biofuels have been promoted as a promising alternative to petroleum. Industry, government and scientific proponents of biofuels claim that they will serve as an alternative to peaking oil, mitigate climate change by reducing greenhouse gas emissions, enhancing farmer incomes, and promoting rural development. But rigorous research and analysis conducted by respected ecologists and social scientists suggests that the large-scale industrial boom in biofuels will be disastrous for farmers, the environment, biodiversity preservation and consumers, particularly, the poor.
In this paper we address the ecological, social and economic implications of biofuel production. We argue that contrary to the false claims of corporations that promote these “green fuels,” the massive cultivation of corn, sugar cane, soybean, oil palm and other crops presently pushed by the fuel crops industry—all to be genetically engineered—will not reduce greenhouse gas emissions, but will displace tens of thousands of farmers, decrease food security in many countries, and accelerate the deforestation and environmental destruction of the Global South.
