VTT performs varied research into the characterization and control of emissions originating from different sources, such as power plants, industrial processes and traffic. For this purpose, VTT has diverse measurement techniques and we also develop new innovations with industry and analyser manufacturers for the determination of emissions together.
Concern about environmental issues is increasing rapidly due to global environmental challenges, such as climate change and global warming, health risks caused by fine particulates etc. This growing demand in environmental monitoring issues (from individuals, companies, politicians and researchers) is creating an urgent need to characterize the emissions, including from those sources which have not been monitored until now. Only then can the cost-effective measurers that are needed (abatement, process optimisation, control, surveillance), be focused on those sources which are the most critical ones.
