On the issue of harmonization of domestic and foreign methods for estimating and forecasting emissions of small vessels

The paper presents a detailed analysis of some foreign methods for estimating and forecasting gross emissions from propulsion systems of motorized boats and small vessels. It also summarizes key input default data, incl. values of specific pollutant emissions for different types of engines, values of some correction factors (engine wear factor, engine load factor, average engine power, specific fuel consumption, average life of the engine, average annual engine operation hours). The results of the study may be useful for harmonizing domestic and foreign methods for inventorying emissions from mobile sources.
