Carbon counting
We have unique experience in measuring the carbon benefit of biofuels.
We have led the oil industry first with the launch of the first carbon-certified® fuel product in 2002 and more recently, as biofuel enters into a mainstream usage, by declaring the carbon savings achieved through all our UK biofuel sales. The lifecycle methodologies and verification processes that we have pioneered have formed the basis for much of the thinking behind the carbon reporting frameworks proposed by the UK Government and the European Commission.
The first low carbon fuel product
In 2002 we introduced the UK’s first “carbon-certified®” fuel - Greenergy GlobalDiesel, a blend of 5% biodiesel and 95% mineral diesel which delivered a guaranteed 5% reduction in greenhouse gas emissions. We certified this carbon reduction by quantifying the emissions throughout the lifecycle, quantifying the precise volumes blended with diesel and allocating emission reduction certificates to deliver the 5% CO2 emission reduction relative to conventional diesel.
Monthly carbon declaration
Within a few years we were routinely blending up to 5% biofuel into all the petrol and diesel we sold. From January 2006 therefore we began producing an independently audited declaration tracking the greenhouse gas emission savings resulting from all these biofuel sales. The monthly savings achieved are published below.
The level of CO2 saving is independently assessed by the Edinburgh Centre for Carbon Management, using a standard methodology published by BR&D Climate Registry. This looks at the whole-of life emissions of fuels from different origins and takes into account the varying carbon intensities of biofuels produced from different feedstocks and in different countries.
Over the last year (14 August 2006 to 14 August 2007), we supplied our customers with 196.8 million litres of biofuel. When compared with standard fuels this replaced in tank, the total avoided emissions for this period were 351,648 tonnes CO2. This is equivalent to taking more than 117,000 average family cars off the road over the same period.*
