Brazil is the world’s biofuel leader, with half of its sugar cane crop providing more than 40 percent of its non-diesel transport fuel. In the United States, where 15 percent of the corn crop provides about 2 percent of the non-diesel transport fuel, ethanol production is growing even more rapidly. This surging growth may allow the U.S. to overtake Brazil as the world’s biofuel leader this year. Both countries are now estimated to be producing ethanol at less than the current cost of gasoline.
As the first-ever global assessment of the potential social and environmental impacts of biofuels, Biofuels for Transportation warns that the large-scale use of biofuels carries significant agricultural and ecological risks. “It is essential that government incentives be used to minimize competition between food and fuel crops and to discourage expansion onto ecologically valuable lands,” says Worldwatch Biofuels Project Manager Suzanne Hunt. However, the report also finds that biofuels have the potential to increase energy security, create new economic opportunities in rural areas, and reduce local pollution and emissions of greenhouse gases.
The report recommends policies to accelerate the development of biofuels, while maximizing the benefits and minimizing the risks. Recommendations include:
- Strengthen the Market. Biofuel policies should focus on market development, based on sound fiscal incentives and support for private investment, infrastructure development, and the building of transportation fleets that are able to use the new fuels.
- Speed the Transition to Next-Generation Technologies. It is critical to expedite the transition to the next generation of biofuel feedstock and technologies, which will allow for dramatically increased production at lower cost, while minimizing environmental impacts.
- Protect the Resource Base. Maintaining soil productivity, water quality, and myriad other ecosystem services is essential. National and international environmental sustainability principles and certification systems are important for protecting resources as well as maintaining public trust in the merits of biofuels.
- Facilitate Sustainable International Biofuel Trade. Continued rapid growth of biofuels will require the development of a true international market in these fuels, unimpeded by the trade restrictions in place today. Freer movement of biofuels around the world should be coupled with social and environmental standards and a credible system to certify compliance.
The report’s findings were discussed today at a conference on Capitol Hill hosted by Worldwatch President Christopher Flavin and GTZ Director General Peter Conze. Participants included policymakers and representatives of the private sector, governments, international agencies, and nongovernmental organizations.
Speakers at the opening session included World Bank President Paul Wolfowitz; Thomas Dorr, Under Secretary at the U.S. Department of Agriculture; and German Ambassador to the United States, Klaus Scharioth. Other conference speakers include R. James Woolsey, Vice President of Booz Allen Hamilton and former Director of Central Intelligence; John Podesta, President and CEO of the Center for American Progress; and representatives from DaimlerChrysler AG, Iogen Corporation, and CHOREN Industries, as well as Suzanne Hunt and other contributors to the biofuels report.
