Year 7 final emissions based on burning a totoal of 162,663 acres of cereal grain. Fall: 92,212 acresSpring: 70,451 acres
Emissions of 1906 tons in year 7 is equal to 69% of the baseline emission level of 2884 tons. The total reduction is 31%. The target was a 50% reduction in PM emissions which was achieved in Year 3 and 4.
