Biofuels: The Climate-Related Threats and Opportunities, and the Need to Develop Policies Based on a Comprehensive Assessment of Their Direct and Indirect Impacts

The Clean Air Task Force warns that the climate benefits of replacing fossil fuels with biofuels are often negated by indirect effects, specifically the release of carbon dioxide when forests and wetlands are cleared to meet increased agricultural demand. The report highlights how the EU's 2003 Biofuel Directive inadvertently drove the destruction of Indonesian peatlands for palm oil, releasing approximately two billion metric tons of CO2 annually. It notes that direct benefits are further undermined by the use of nitrogen-based fertilizers in crops like rapeseed. The author recommends slowing the rush toward production mandates, developing analytic tools over the next 2-3 years to quantify market-driven impacts, and focusing on niche policies for waste feedstocks, algae, and biomass from marginal lands.

• Indirect climate effects, particularly the conversion of forests and wetlands into farmland to meet food and feed demand displaced by biofuel crops, can outweigh the direct benefits of replacing fossil fuels.
• The EU's 2003 Biofuel Directive contributed to the destruction of Indonesian peatlands for palm oil production, which releases about two billion metric tons of CO2 annually, representing 8% of global fossil fuel CO2 emissions.
• Direct climate benefits of biofuels are often diminished by production-related emissions; for example, rapeseed-based biodiesel in Europe has a CO2-equivalent-per-kilometer similar to petroleum diesel due to nitrous oxide emissions from nitrogen-based fertilizers.
• Biofuel production has negatively impacted food security and prices, as seen in the 2006 corn price spike in the US and subsequent street protests in Mexico in January 2007.
• Current 'life-cycle' analyses are insufficient because they frequently ignore critical factors such as the nitrogen cycle, land-use changes, and market-driven indirect effects.
• The author suggests that for the next twenty years, biofuels are unlikely to significantly reduce domestic mobility climate impacts due to barriers including limited waste feedstocks and the high climate cost of land conversion.
