Driving lower emissions with UPM BioVerno

​UPM BioVerno is a fuel that significantly reduces both CO2 emissions and tailpipe emissions that harm the local environment. The low tailpipe emissions make UPM BioVerno diesel an even more sustainable choice for drivers.
​UPM BioVerno has been tested in a number of engines and car makes and models across several research institutes such as VTT Technical Research Centre of Finland Ltd, University of Vaasa in Finland and FEV, an internationally recognised vehicle engineering company based in Germany.

​UPM BioVerno reduces tailpipe emissions

​Using wood-based UPM BioVerno diesel significantly reduces road traffic tailpipe emissions. All the emission tests carried out on UPM BioVerno are done using conventional fossil diesel as a reference fuel. According to several studies, UPM BioVerno reduces tailpipe emissions, such as particle mass, hydrocarbon, carbon dioxide, nitrogen oxide and carbon monoxide emissions, by up to dozens of percent compared to conventional diesel fuel, depending on vehicle technology.

All the tests showed similar or improved efficiency of the engine, without compromising the engine power, when UPM BioVerno was introduced to the fuel blend. In addition, it could be shown that by using 100% UPM BioVerno diesel fuel consumption decreased.

UPM BioVerno also reduces road traffic emissions as a blend


FEV Germany carried out a series of tests on UPM BioVerno's effect on engine functionality and emissions with both a diesel blend containing 30% UPM BioVerno and 100% UPM BioVerno diesel. In addition to measuring engine power and fuel consumption, the tests focused on exhaust gas emissions and the performance of UPM BioVerno compared with conventional diesel.

The high level of quality and higher cetane number offered by UPM BioVerno provide cleaner combustion in the engine and thus help to achieve considerably lower exhaust gas emissions. Clear differences compared to conventional diesel were gained even with a 30% diesel blend.

“The tests performed on renewable UPM BioVerno showed that even as a 30% blending component, the accumulated hydrocarbon (HC) emissions were reduced by more than 50% and the carbon monoxide (CO) emissions by more than 40% compared to reference fossil diesel. Our tests also showed good results in NOx emissions and efficiency", says Thorsten Schnorbus, Manager Passenger Car Diesel, FEV Germany.

Heavy-duty vehicle tests:UPM BioVerno bus tests

UPM BioVerno has been tested in Euro III class bus engines at VTT and in field tests carried out on Volvo Euro VI class buses in collaboration with Helsinki Region Transport (HSL) and VTT. The field tests are also supported by St1, Volvo and the bus operator Transdev Finland.

In the tests carried out at VTT, the tailpipe emissions of UPM BioVerno were compared with the emissions of other paraffinic fuels on the market and with the emissions produced when using regular fossil diesel.

Compared to regular diesel, all the paraffinic fuels, including UPM BioVerno, clearly reduced the amount of nitrogen oxides (NOx) and particle mass (PM), which are the worst pollutants in exhaust gases. The reductions in NOx and PM emissions (g/km) achieved using UPM BioVerno were at the same level as the reductions achieved using other paraffinic fuels.

​Heavy-duty vehicle tests: UPM BioVerno in off-road engines

​UPM BioVerno has also been tested in heavy-duty engines at the University of Vaasa, Finland.

The engine experiments with modern Finnish off-road engines showed that the more UPM BioVerno there was in the fuel blend, the lower were the CO and HC emissions of the engine. For all studied fuels and fuel blends, the smoke readings were very low.

Master's degree student Nelli Vanhala (on the left) and Laboratory Engineer Olav Nilsson are studying UPM BioVerno diesel at the University of Vaasa Faculty of Technology.

"The lowest CO and HC emissions were recorded when running the engines with 100% BioVerno. Neat UPM BioVerno also resulted in the lowest particulate matter emissions at idle."

​UPM BioVerno is a stable fuel that functions well in passenger car fuel systems

​The chemical structure of wood-based, renewable UPM BioVerno diesel is similar to the chemical structure of regular diesel as it is a pure hydrocarbon. Its performance in passenger car engines is at the same level as that of the best commercial diesels, and it has good storage stability properties.

VTT carried out long-term tests to examine the stability of UPM BioVerno and to evaluate the effects the fuel would have on passenger car engines and fuel systems. Various plastic, rubber and metal parts typically found in diesel-powered passenger car fuel systems were exposed to UPM BioVerno for 12 months. Other fuels were also tested simultaneously.
The stability of UPM BioVerno was good in the 12-month storage stability test that was implemented at room temperature and without adding any preservatives to the fuel. The colour of the fuel remained clear, and screening tests did not reveal any bacteria, moulds or yeasts in the fuel.

No significant changes were identified in the materials of the engines or fuel systems. Additionally, UPM BioVerno did not cause any corrosion of metal parts. Corrosion could not be identified even when the metal parts exposed to the fuel were examined using a scanning electron microscope.
