The transport sector is the largest source of carbon dioxide emissions in the UK, accounting for approximately 29% of total emissions. Heavy goods vehicles (HGVs) produce 17% of road transport emissions, despite representing only around 1% of the UK road transport fleet.
HGVs fuelled by biomethane generated by anaerobic digestion plants are one of the only commercially available, scalable and cost-competitive solutions capable of materially reducing emissions from long-haul road transport today.
The take-up of Compressed Natural Gas (CNG) offers fleet operators the opportunity to significantly lower their emissions, whilst also providing a cheaper whole-life alternative to comparable diesel vehicles.
