This paper analyses Brazil's experience with biofuels, focusing on the central role of the federal government as the main force driving the implementation of alternative locally produced ethanol (ethyl alcohol) and biodiesel. The pioneering, large scale ethanol programme that started over 30 years ago can be considered the most successful experience with the use of biofuels to date, as the government was able to rapidly implement the use of ethanol (ethyl alcohol) as a substitute for petrol in the 1970s and 1980s. The work contributes to the general discussion of sustainable and renewable energy sources and sets out the key policy mechanisms used. The paper also innovatively looks at the second large governmental intervention in the renewable fuels market – the biodiesel programme. In addition to the contribution to the debate surrounding command-and-control measures and economic incentive instruments, the paper analyses how lessons learned from the ethanol experiment were taken into consideration in the design and implementation of the biodiesel mandate, including social and environmental facets. It emphasizes the uniqueness of producing sugarcane ethanol in the Brazilian context and how attempts to carry out similar fast growing biofuels programmes may not be possible in other parts of the world.

Abstract: Alongside with biofuel development, social acceptance issues have been underestimated. While social acceptance can emerge as powerful barrier for biofuel development, this article provides discussion on social acceptance in biofuel context. An acceptance framework based on life cycle biofuel production had been referred for a better understanding on social acceptance issues. Malaysia has been referred for the discussion as the country has faced with acceptance issue in their biofuel program. The discussion point out different societal groups will demand specific consideration for either support or oppose biofuel. This paper concludes that biofuel development will be constraint if social acceptance issues remain neglect. [Copyright &y& Elsevier]

Traditional biomass remains the dominant contributor to the energy supply of a large number of developing countries, where it serves the household energy needs of over a third of humanity in traditional cookstoves or open fires. Efforts to reduce the enormous human health, socioeconomic, and environmental impacts by shifting to cleaner cookstoves and cleaner biomass-derived fuels have had some success, but much more needs to be done, possibly including the expanded use of fossil-derived fuels. Concurrently, biomass is rapidly expanding as a commercial energy source, especially for transport fuels. Bioenergy can positively contribute to climate goals and rural livelihoods; however, if not implemented carefully, it could exacerbate degradation of land, water bodies, and ecosystems; reduce food security; and increase greenhouse gas (GHG) emissions. For large-scale commercial biofuels to contribute to sustainable development will require agriculturally sustainable methods and markets that provide enhanced livelihood opportunities and equitable terms of trade. The challenge lies in translating the opportunity into reality. [ABSTRACT FROM AUTHOR]
