Panel II - Biofuels

Alfred Szwarc

IPC’s Fall Seminar “Sustainability in the Food & Agricultural Sector”

Stratford-Upon-Avon, October 15 – 16, 2007

slide2

UNICA is the leading Brazilian association of sugar & ethanol producers

  • Ethanol related UNICA’s goals:
  • structure an international fuel ethanol market
  • consolidate ethanol as a global energy commodity
  • develop new applications and markets
  • incentive adoption of best practices
slide3

Ethanol from Sugar Cane

  • The Industry in Brazil
  • Sustainability Issues
  • Trade Issues
  • Concluding Remarks
slide4

Sugar Cane

Sugar Cane is the prime ethanol feedstok in Brazil

Semi-perennial plant: lasts for about 5 crop seasons with high yields and has many benefits over traditional row crops:

less energy to plant & cultivate; root system reduces erosion & effective carbon uptake; relatively low defensive & fertilizer requirements; many varieties.

slide12

Water Consumption

  • In most of the Brazilian territory “Dry Farming” is the dominant practice because of sufficient rainfall.
  • Irrigation in Brazil’s crop areas has been required in less than 4 M ha (< 6% of present agriculture land).
  • Irrigation in sugar cane production is more widespread in the NE, however “Salvation Irrigation” and “Suplementary Irrigation” are adopted according to the need.
  • Rational use of water in the sugar cane industry has increased considerably with reuse and recycle practices.
  • Presently the average consumption of water in São Paulo State’s sugar cane industry is in the order of 1.8 m3/tonne of sugar cane (65% less than in 1997); ongoing efforts to reduce further this volume.

Ferti-irrigation

Ferti-Irrigation with stllage (vinasse) helps to reduce use of water & chemical fertilizers and is a good practice to recover soil fertility

Greenhouse Gas Emissions

  • Avoided GHG emissions in Brazil in 2003 due to the sugar cane industry are equivalent to the emission of GHG by Norway:
  • ethanol substituting for gasoline: 27,5 M t CO2 eq.bagasse in sugar production: 5,7 M t CO2 eq.

slide27

Agroenergy Dilemma

Energy X Food X Feed

  • Rapid demand growth for ethanol, dry climate and strong demand from Asia have all been contributing to grain prices increase;
  • While ethanol production has been increasing in Brazil sugar prices (sugar is food) have been low and stable;
  • Debate has been fueled by a campaign against biofuels and ethanol has become the preferred scapegoat to justify price increase;
  • Hunger has been due primarily to inadequate income distribution not food scarcity;
  • Agriculture productivity is increasing and there is considerable arable land to be used;
  • Cellulosic ethanol is a good promise;
slide28

Ethanol Sustainability

  • Based on the “Triple Bottom Line” requirements: SOCIAL, ECONOMICALandENVIRONMENTAL.
  • BENCHMARKED against fossil fuels.
  • UNIVERSAL: applied internationally to all producers, feedstocks & production processes.
  • Agreed within aMULTI-STAKEHOLDERnegotiation process.
  • Based on a transparent process defined byCLEAR PRINCIPLES, BALANCED CRITERIA and OBJECTIVE INDICATORS.
  • VOLUNTARY:to reward those who invest in the process.
  • Applied PROGRESSIVELY.

Ethanol International Trade

  • Energy Security
  • Diversification of Energy Sources & Energy Mix
  • Environmental Issues (global warming, urban pollution)
  • Rural Development

Drivers

Challenges

  • Doha ?
  • Reduction/Elimination of Trade Barriers
  • More Producers & Consumers
  • Harmonization of Product Quality Standards
  • Closer Relationship with Stakeholders (motor industry, oil industry, fuel distributors, governments, NGO’s etc.)
  • Wider Use of Futures Market Contracts (BM&F, NYBOT, CBOT etc.)
slide30

Concluding Remarks

Growing popularity of bioethanol has created momentum for the development of an international market.

Sound policies, environmental care, social responsibility, technological development, standards harmonization, trade barriers elimination and partnershipare key for the successful development of a well structured international market.
