Queens University Belfast's analysis of R100's CO2 savings has been calculated by using the Freemans Transport fleet’s Mercedes Fleetboard data:

 

R100 in a B60 blend achieves CO2 savings across the fleet 

​

• 1.6kg/lit relative to mineral diesel 

• 1.41kg/lit relative to B7 diesel

​

Relative to B7 that equates across the fleet to

 

• weekly savings of 64,000 kgCO2 

• annual savings of over 3,300 MtCO2 

​

Queens University concluded

 

• further savings can be calculated as this is a waste-to-energy fuel​

• therefore the whole life factor would be 80-85% (rather than the 45-65% factor for vegetable oil biodiesel)
