The Finnish Terminology Centre TSK started a terminology project in September for the Statistics Finland. The aim of the project is to collect and harmonize or prepare definitions and notes for circa 30 central concepts related to energy and release statistics. Terms and concept descriptions are given in Finnish. The terminologist prepares material for work shops, where concepts are discussed and terms and concept descriptions are processed with the experts of the Statistics Finland. The terminology work should be ready by the end of the year.
