At our mail sorting centres in the Netherlands, we have implemented electric hybrid heating and cooling systems, replacing the installations powered by gas, resulting in a reduction in gas consumption and increase in electricity consumption. The electricity consumption has been further optimised in line with volume developments. The share of renewable electricity remained stable in 2023. Our energy consumption per square meter decreased by 8% compared to 2022.
