Volvo, a prestigious automobile manufacturer, has recently united with Saint Gobain. Through this agreement, a fleet of Saint-Gobain delivery trucks that transport Celotex goods across the UK were designed, ultimately reducing carbon emissions by up to 1,300 tonnes annually. This is another example of how Saint-Gobain are constantly innovating in their fight against climate change.

High-pressure direct ignition (HPDI), a technology used in the new vehicles, enables performance-preserving carbon emission reductions. By initiating an ignition cycle, Volvo's HPDI technology uses less fuel than a gas-only spark ignition system. Comparing this to a typical diesel system, the emissions are reduced by up to 20%. Compared to diesel-powered engines, LNG engines release far less CO2 per mile. The automobiles are fueled by renewable-source LNG made from biomethane.
