The group’s primary source of energy is from the use of carbon-neutral bagasse which substantially decreases process GHG emissions at Illovo’s operations in comparison to the use of fossil fuel sources. Certain of our operations have adopted “green cane harvesting”, where feasible, which decreases agricultural emissions caused by the burning of sugar cane prior to harvesting. During “green cane harvesting”, green biomass is stripped off the cane, either mechanically or by hand, as an alternative to the traditional practice of burning. This trash removed from the cane is either left infield to render back into the soil, potentially improving soil moisture retention, nutrient levels and carbon sequestration, or used as a renewable boiler fuel. Green cane harvesting operations are currently being undertaken in Malawi, Swaziland and South Africa.
Our greenhouse gas inventory incorporates all operations over which we have direct operational control. GHG source categories covered in the inventory include the combustion of fossil fuels, infield cane burning and GHG emissions associated with the generation of purchased electricity and steam. The approach applied for calculating GHG emissions involves the use of emissions factors. Emission factors are representative values relating the quantity of an emission with an activity associated with the release of that emission. Country specific emission factors have been applied where available, otherwise accepted international proxy emission factors have been adopted from reputable sources such as the Intergovernmental Panel on Climate Change (IPCC), UK Department for Environment or US Energy Information Administration. The electricity grid emission factors applied to our areas of operation vary significantly as a result of the GHG emission intensity of the electricity generation technologies utilised by the countries within which we operate.
Illovo is committed to supporting global climate change mitigation. In terms of its strategy, the company aims to reduce greenhouse gas (GHG) emissions across the group by 10.7% on the 2010 emissions level by 2020.
We continue to respond to the Carbon Disclosure Project (CDP), demonstrating our commitment to transparency concerning our GHG emissions reduction initiatives at our operations and to supporting global climate change mitigation.
