Table 1. The burden of deforestation due to biodiesel in Mato Grosso


Factor Range of estimates Source/notes
A Forest clearance attributable to cultivation (remaining clearance is due to grazing) 16-20% Morton et al. (2006); Nepstad et al. (2009)
B Soy as percentage of total cultivation area (ignoring double cropping) 84% Wright (2009)
C Oil as percentage of soy crop, by weight 18%
D Oil as percentage of soy crop, by market value 42% Based on 3:1 ratio of $/tonne (World Bank 2008)
E Percentage of soy oil required to meet Brazil’s biofuel blending targets 35% Hall et al. (2009)
F Forest loss due to soy 13.4-16.8% A x B
G Forest loss due to soy oil, by weight 2.4-3.0% F x C
H Forest loss due to soy oil, by $ value 5.6-7.0% F x D
J Range of estimates of forest loss due to biodiesel based on weight and $ values 0.8-2.6% Min. G x E, max. H x E
K Alternative estimate of forest loss due to biodiesel, based on economic inseparability of soy oil and soy meal 4.6-5.9% F x E; burden calculated on total soy crop, not on oil only.
