- •
An LCA approach was used to model energy and GHGs for sugarcane in South Africa.
- •
Effects of irrigation, cane burning, mechanized harvest, and regions were modeled.
- •
Irrigated cane requires more energy but has similar emissions to non-irrigated cane.
- •
Green cane harvesting reduces energy inputs (4%) and GHG emissions (16%).
- •
Mechanization reduces yields and thus increases energy inputs and GHG emissions.
