What is HVO?
HVO is a renewable, biodegradable alternative to Diesel. It’s made from certified waste materials meaning net CO2 emissions are reduced by up to 90%1. HVO also has approval from sustainability schemes2.
A seamless transition
Our teams worked closely with vehicle manufacturers and our chosen supplier, Crown Oil3. Working together ensured a smooth rollout across our fleet with minimal operational impacts.
Coryton was the first filling plant to switch over to HVO, which marked the beginning of a nationwide rollout. And today, 12 of our sites – from Inverness to Newbury, Grangemouth, and Plymouth are now running eligible vehicles on HVO.
Already making a difference
Switching to HVO is already delivering tangible benefits:
- Lower carbon footprint – estimated 9,500-tonne carbon reduction in 20251.
- Reduced environmental risks - easier to clean up in the event of a spill compared to Diesel.
- No vehicle modifications needed – refuelling is no different to using Diesel.
A commitment beyond today...
As we continue to invest in sustainable solutions we will ensure a lasting impact for our customers, and the planet. At Calor, we're driving our sustainability goal forward.
