The aim of work is to ascertain the impact of changes in the regulations on atmospheric air protection from pollution on further exploitation of existing and construction of new energy plants, development of new processes and boiler equipment for biomass burning. Paper provides an analysis of changes in the international documents, standards and normative acts of Ukraine concerning limitation of pollutants emission from energy plants with biomass combustion. Recast EU directive provide environmental requirements for large combustion plants (above 50 MW) which are differentiated depending on their thermal input and valid for new plants since 2018, and for existing plants should be implemented in two stages  – since 2014 and 2028 years. For large combustion plants the regulations of Ukraine envisaged a gradual transition to EU environmental requirements till year 2033. Because of peculiarities of the modern environmental requirements introduction, biomass and coal co-firing at existing large power plants of Ukraine can become real close to the period of 2028-2033 years. In 2015 the EU adopted environmental requirements for medium-sized combustion plants (1-50 MW) which are valid for new plants since 2018, and for existing plants with a thermal input more than 5 MW they will enter into force in 2025, and at thermal input 1-5 MW – in 2030. In Ukraine as to medium-sized combustion plant the technological environmental requirements are accepted only for sunflower husks usage combustion, but for other solid fuels burning the requirements common for all stationary sources of emissions are valid. At reconstruction and extending operation of the existing medium-sized husks combustion plants one can focus on perspective technological emission limitations established in Ukraine. In Ukraine the common particulate emission limitations at solid fuels combustion are lower, than that of the standard EN 303-5:2012 for boilers (up to 500 kW) of third class especially at burning peat and straw, so there is a need to develop primary measures for particulate emission reduction to common limitations.
