A policy of openess to drive improvement


We are open about the biofuels that we supply. Disclosing detailed information about the origin and carbon impact of our biofuels helps to keep us focused on the environmental and social impact of our sourcing operations, so we can strive to do better.

We are the only UK fuel supplier to make available such detailed information about the biofuels we use.

We provide information about our biofuels in the following formats:

We have mapped our supply chain on BioCarbon Tracker, a map global carbon reserves and the threats they face.

The map shows where our suppliers are located, and whether they are in an area where carbon reserves have been destroyed or at risk. By looking at our suppliers in the context of carbon reserves, we can evaluate risk and prioritise our actions more effectively.

Biofuel raw materials

Year to date (15 April 2013 to 14 Nov 2013)


We have made significant investments in our biodiesel manufacturing infrastructure in order to be able to increase our usage of waste based biodiesel, with technical enhancements to our manufacturing facility at Immingham and construction of a new biodiesel pre-processing facility giving us the ability us to process a broader range of waste oils and fats.

As a result, the vast majority of the biodiesel in Greenergy's diesel is now derived from waste products including:

  • Used cooking oil
  • Tallow, which is a by-product of the meat processing industry.


About half of the bioethanol in our petrol has been derived from corn. The remainder was produced from wheat and sugar beet grown in the UK and Europe, as well from Brazilian and Peruvian sugar cane, with a small proportion comprising a renewable petrol blend component made from crude glycerine.
