SCA is the first company in the world to equip its entire fleet of vessels with catalytic converter cleaning. For an investment of SEK 20 million (around $2.5 million) they claim to be able to reduce NOX (oxides of nitrogen) emissions by 90%, 1400 tonnes per year in all. "That's equivalent to the NOX emissions for all our truck haulage operations, both of timber and of finished products", says Rolf Johannesson, CEO at SCA Transforest.
