presented at the IDB Conference “Sustainable Energy and Climate Change in Latin America and the Caribbean”, Washington DC, USA, November 28-29, 2006

Biofuels for Transport
Fuel Feedstock Regions where currently produced GHG reduction v. petroleum Production cost Biofuels yield per hectare

Deforestation ?

Food crops
competition for water ?

Protected & other reserved areas

Energy crops & plantations

Loss of biodiversity?

Sustainability Standards

Sustainable Biomass

“Sustainability Standards for Biomass” prepared for WWF, Nov. 2006

•
• •

Synopsis of sustainability concerns for biomass
Global review of existing sustainability criteria and certification systems Recommendation of „core“ standards, and for follow-up process

Standards: Summary

Sustainable Biomass

Only land use + GHG reduction have global scope Both could be implemented within a few years if resources are made available

Opportunities!
• Some biofuels competitive for heat/ electricity/transport (rural, Brazil)

Sustainable Biomass

• Biogas from residues + perennial crops
• 2nd generation biofuels for transport > 2010

• CDM could boost biofuels
• Employment, access to energy, income generation (food security)

Establish standards and best practise projects for sustainable biofuels!
