Tab. 28 > Emission factors of appliances with 2-stroke petrol engines (in g per kWh)
For appliances put into circulation before 2004, the emission factors are based on the
corresponding assumptions (Pre-EU) instead of on emission limit values. The year of
introduction is shown in parentheses.Figures in italics: assumption concerning future
development of emission factors.
