Funding was also provided by Cornell University's Biogeochemistry and Biocomplexity Initiative and an endowment given to Cornell University by David R. Atkinson.

Project Overview

The worldwide use of liquid biofuels accelerated remarkably since the early part of the 21st Century. While most production today occurs in Brazil and the US, increased production is expected not only in these countries but throughout Europe, southeast Asia, and Africa in coming years. In response to environmental concerns over this expansion, the Scientific Committee on Problems of the Environment (SCOPE) of the International Council of Science (ICSU) commissioned the International SCOPE Biofuels Project (2007-2010).

Liquid biofuels have been heavily criticized for both as a fuel source and as a “greener” fuel alternative. Much of the criticism has focused on first-generation ethanol (i.e ethanol produced from corn) and many articles in both the scientific literature and the popular press have reported on a host of environmental problems associated with this technology. Potential issues with ethanol produced from sugarcane, biodiesel produced from oil palms, soya bean, and other crops, and with “second-generation” ethanol produced from cellulose, have received far less scrutiny and discussion so far. There are nonetheless potentially severe consequences on the environment from these technologies as well.

The charge of the International SCOPE Biofuels Project was to perform an objective, science-based assessment in order to provide a comprehensive, systematic, and comparative analysis of the environmental benefits and costs of biofuel technologies. The project was conducted both at the global and sub-global levels, so as to take into account specific physical and societal dimensions in the main regions of the world. The project evaluated both first and second-generation liquid fuels, including both ethanol and biodiesel. The project also evaluated gaseous biofuels (methane) and the use of solid biomass for energy (for example through pyrolysis and direct combustion).

The fundamental goal of the Project was to compile and synthesize the best available science-based objective information to address the question “what are the characteristics of an environmentally desirable and sustainable biofuel?” The Project held a planning meeting in Miami, Florida in 2007, held an international workshop in Gummersbach, Germany in 2008, and published a consensus report in 2009. Output from the Project also informed the 2009 report from UNEP on biofuels.

Rapid Assessment Process (RAP) on Biofuels and the Environment

Workshop held 22-25 September 2008
Grand City Hotel, Gummersbach, Germany

Co-Chaired by:
Robert W. Howarth, Cornell University
Stefan Bringezu, Wuppertal Institute

The SCOPE Rapid Assessment Process (RAP) workshop brought together a group of nearly 40 high calibre, international experts to deliberate on the key environmental impacts of biofuels production and expansion and future perspectives of more sustainable biofuel systems. Cross-cutting economic and social aspects were discussed as well. The results from the deliberations provided policy relevant information to support decision making by industry, national governments, international institutions and NGOs and was published in a SCOPE Policy Brief.

Prior to the workshop, expert authors were invited to provide papers (1 per author) on key issues as input to the meeting. Workshop participants discussed the various concerns from different perspectives, while focusing on three to four cross-cutting questions. The workshop was scheduled such that 2 working groups met at any given time, allowing participants to take part in at least 2 groups - a scheme similar to the proven Dahlem conferences. Session chairs and rapporteurs ensured a productive outcome, kept track of the record, and synthesised results in a well-balanced and thorough manner. At the end of the workshop the key content of the proceedings was drafted along with the SCOPE-UNESCO Policy Brief. The entire volume underwent subsequent review, refinement, and editing prior to publication of the final volume in April of 2009.
