Distribution:

Saint Gobain has partnered with Volvo, a leading automotive manufacturer. This partnership ensured a fleet of Saint-Gobain's delivery vehicles that deliver Celotex products throughout the UK were updated to help save up to 1,300 tonnes of carbon emission each year.

The new vehicles use a system called high-pressure direct ignition (HPDI), which allows them to reduce carbon emissions whilst maintaining performance. Volvo’s HPDI technology uses less fuel than a gas-only spark ignition system by creating an ignition cycle. This creates up to 20% fewer emissions than a standard diesel system. LNG engines emit significantly less CO2 per mile than the diesel equivalent. The vehicles are fuelled with bio-methane-based LNG from renewable sources making
