REPORT FROM THE COMMISSION TO THE EUROPEAN PARLIAMENT AND  

THE COUNCIL  

on the exercise of the power to adopt delegated acts conferred on the Commission 
pursuant to Directive (EU) 2015/2193 of the European Parliament and of the Council on 
the limitation of emissions of certain pollutants into the air from medium combustion 
plants 

1.  INTRODUCTION  

Directive (EU) 2015/2193 (1) of the European Parliament and of the Council of 25 November 
2015 put in place a regulatory framework to limit emissions of sulphur dioxide (SO2), nitrogen 
oxides (NOx) and dust into the air from medium combustion plants. The aim is to reduce the 
related  risks  to  human  health  and  the  environment.  That  Directive  also  lays  down  rules  to 
monitor  emissions  of  carbon  monoxide  (CO).  Article  13  of  that  Directive  allows  the 
Commission  to  adopt  delegated  acts  in  order  to  adapt  the  provisions  on  assessment  of 
compliance set out in point 2 of Part 2 of Annex III to scientific and technical progress. Article 
14 addresses the procedure and conditions under which the Commission is granted the authority 
to adopt delegated acts. 

2.  LEGAL BASIS  

This report is required under Article 14(2) of Directive (EU) 2015/2193, whereby the power to 
adopt  delegated  acts  is  conferred  on  the  Commission  for  a  period  of  five  years  from  18 
December  2015  and  that  requires  the  Commission  to  draw  up  a  report  in  respect  of  that 
delegation of power. The delegation of power is tacitly extended for periods of an identical 
duration, unless the European Parliament or the Council oppose such an extension no later than 
three months before the end of each period. Article 14(3) states that the delegation of power 
may be revoked at any time by the European Parliament or the Council. 

The Commission adopted the previous report (2) on the exercise of the delegation of power 
conferred on it with regard to Directive (EU) 2015/2193 on 3 August 2020. It reported that it 
had not adopted any delegated acts and invited the European Parliament and the Council to 
take note of that report. 

3.  EXERCISE OF THE DELEGATION  

The  Commission  reports  that  over  the  past  five  years  (2020  –  2025),  it  has  not  adopted 
delegated acts given (i) the recent dates of application of Directive (EU) 2015/2193 for some 
of its provisions (3); and (ii) the absence of information on technical and scientific progress 
linked to the provisions laid down in point 2 of Part 2 of Annex III related to the assessment of 

(1) OJ L 313, 28.11.2015, p.1. 
(2) eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:52020DC0351. 
(3) Emission limit values laid down in Annex II of the Directive are to be complied with from 1 January 2025 for 
existing plants with a rated thermal input greater than 5 MW and from 1 January 2030 for plants with a rated 
thermal input equal to or greater than 1 MW and less than or equal to 5 MW.

compliance of measured emission values with emission limit values in the case of continuous 
measurements. 

4.  CONCLUSION  

Over the past five years (2020 – 2025), the Commission has not exercised the delegated powers 
conferred on it under Directive (EU) 2015/2193. It invites the European Parliament and the 
Council to take note of this report.
