We strive for continuous improvement of our environmental performance. We aim to minimize the environmental impact of our energy consumption, water use, and waste generation.
Our main environmental impacts are energy and carbon, water and waste. We consider our impacts principally within our own operations, but are increasingly focusing on the sustainability of our agricultural supply chain, particularly our principal raw material, corn. Our environmental performance in 2017 showed positive progress in our primary carbon footprint, waste to landfill and water usage. Our energy use remained largely unchanged.
Each year we publish in our Annual Report our key performance indicators and how we have performed.
