Lessons learned |

| Initiative |
Producing malt in a sustainable way requires a daily commitment to continuous improvement. Reducing energy consumption and emissions is one of Boortmalt’s four main objectives for sustainable development, along with water conservation, sustainable agriculture, and health and safety issues. “Our goal is to reduce CO2 emissions by at least 50% by 2030 across Boortmalt's activities worldwide, in line with the Paris climate agreements”, states Yvan Schaepman, Boortmalt CEO (malting subsidiary of the Axereal group). For several years, Boortmalt has been investing in alternative energy sources to reduce its carbon emissions and limit its consumption of fossil fuels. The Issoudun site is one of the most advanced malting plants in the carbon reduction process, as it is demonstrating once again with this latest development.
