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