Sustainability is at the heart of ES Group’s philosophy and for EST this means regular assessment of their fleet thus enhancing its green credentials. The transfer to Euro 5 standard is the latest in a series of measures taken to reduce EST’s emissions, with their trucks now producing particle emissions 25% below the EEV (Enhanced Environmentally friendly Vehicles) standard. EST is setting up its own Environmental Management System in line with ISO14001 and hopes to achieve full accreditation shortly.
