NESTE OIL AND STORA ENSO TO JOIN FORCES IN BIOFUEL DEVELOPMENT


Neste Oil signed an agreement today with Stora Enso, an integrated paper,       
packaging, and forest products company, to join forces to develop technology for
producing new-generation biofuels from wood residues to replace fossil fuels and
cut greenhouse gases. The first step will be to design and build a demonstration
plant at Stora Enso's Varkaus Mill in Finland. The plant, owned on a 50/50 basis
by the two companies, is expected to start up in 2008 and will produce heat and 
electricity for use locally and crude biodiesel to be refined into commercial   
fuel at Neste Oil's refinery in Porvoo.                                         

Expertise from Neste Oil, Stora Enso, and VTT Technical Research Centre of      
Finland will be utilized to implement the development phase and commercialize   
wood-based biofuel production. Neste Oil and Stora Enso see the growing biofuel 
market in Europe as a promising and sustainable business opportunity for meeting
the increasing demand for premium-quality products made from a wide variety of  
feedstocks. The challenges related to generation of clean synthesis gas from    
wood will need to be solved before wood-based biomass can be used in biofuel    
production. The project will also focus on using Fischer-Tropsch process to     
produce crude biodiesel from gas.                                               

The EUR 14 million demonstration plant will be integrated into the energy       
infrastructure of the Varkaus Mill, and the gas produced will equal the energy  
needed to heat 4,300 homes and cut local carbon dioxide emissions significantly.

Full-scale commercial production
                                                
Following the development phase and completion of the technical solutions, and  
after the partners have gained sufficient experience from the demonstration     
plant, the joint venture will build a full-scale commercial production plant at 
one of Stora Enso's mills. This facility will be owned on a 50/50 basis by the  
JV partners.                                                                    

Stora Enso will be responsible for supplying wood biomass and utilizing heat    
generated. Wood biomass will be supplied from forests according to ecological   
preconditions. Neste Oil's responsibility will final refining and marketing of  
the biofuel.                                                                    

A natural step forward in cutting greenhouse gases
                              
The European Union has set a target of replacing 5.75% (18 million tons) of the 
fossil fuels used in transportation with biofuels by 2010 and 10% by 2020, This 
will mean replacing 30 million tons of fossil fuels and will require significant
increases in biofuel production.                                                

Developing wood-based biofuels is a logical step for Neste Oil and underpins the
company's strategic goal of producing high-quality traffic fuels from a broad   
base of feedstocks. The project is designed to complement Neste Oil's biofuel   
portfolio. The company is currently commissioning its first plant to produce    
170,000 t/a of NExBTL Renewable Diesel, a high-quality fuel offering excellent  
engine performance and low tailpipe emissions, from vegetable oil and animal fat
at its Porvoo refinery in Finland. A second similar plant is also under         
construction at Porvoo.
