Anti-smog resolution

1. It limits the generation of new sources of pollutant emissions

Since July 1, 2017, it will not be possible in the Malopolska Region to exploit a new coal or wood fired boiler or a wood burning fireplace with emission parameters worse than those set in the EU Ecodesign Regulations:

  • People who are building new houses, renovating with replacing a boiler or a fireplace or just replacing a boiler or a fireplace will be required to install a modern ecodesign device.

  • For the residents who already use green heating – district heating, gas, oil, electric heating or heat pumps – the resolution will not introduce any new obligations or restrictions. However, if they want to abandon the current heating for coal or wood, they will have to immediately install a modern boiler that meets the ecodesign requirements of the EU regulations.


2. It sets long transition periods for the currently used coal and wood boilers

 obszar roboczy

  • By the end of 2022, it will be necessary to replace boilers with those using carbon or wood and not meeting any emission standards. Residents will have 6 years to exchange these boilers. At present it is possible to use the municipal funds from the available co-financing of the programs exchanging boilers from the funds of the Regional Operational Program of the Malopolska Region or the WFOŚiGW in Krakow. In the future – after the end of the co-financing programs – users will be obliged to replace them on their own.
  • By the end of 2026, the boilers that currently meet the basic emission requirements of Class 3 or Class 4 according to the PN-EN 303-5: 2012 standard will have to be replaced. Residents will have 10 years for the replacement. This is longer than the lifetime of the boilers, which in practice is usually 8-10 years.
  • Boilers meeting the requirements of Class 5 according to the PN-EN 303-5:2012 standard that are already in operation or will be installed by the end of June 2017 will be used up to the end of their service life.

3. It introduces requirements for the quality of the used fuels to eliminate carbon waste and wet wood

 obszar roboczy

  • Since 1 July 2017, the ban on the use of coal muds and concentration floatation will be imposed in the whole Malopolska Region. The fractions are actually coal waste – fine coal particulate matter of up to 3mm, containing large amounts of moisture, ash and other pollutants that contribute to large emissions when burning.
  • A ban on burning wood and biomass with a moisture content greater than 20% will be introduced. This means that the wood before the burning should be seasoned – its drying should last at least two seasons. Dry wood is characterized by significantly higher calorific value and lower pollutant emissions than raw wood.

4. It introduces the obligation to retrofit fireplaces with emission reduction devices

  • Since July 1, 2017, the newly installed fireplaces (also called room heaters, tiled stoves and popular “goats”) will have to meet the ecodesign requirements. This also applies to installing fireplaces in the existing buildings, e.g. when replacing with a new one.
  • Since 2023, only the fireplaces that meet ecodesign requirements or fireplaces with a heat efficiency of at least 80% will be permitted. The heat performance data should include the technical documentation or the fireplace instructions.
  • The fireplaces that do not meet ecodesign or heat efficiency requirements at the level of at least 80%,, since 2023, will need to be equipped with a device reducing particulate matter up to the ecodesign requirements.

5. Controlling adherence to the restrictions introduced

  • The resolution concerns the use of fuels and heating systems, it will not restrict trade in boilers, fireplaces or coal or wood, because the regional Sejmik does not have the power to introduce legislation in this area. Relevant regulations should be established at the national level.
  • Supervision of compliance with the requirements of the resolution will be carried out by authorized services (city guards and municipal police, authorized employees of municipalities, police) on the basis of documents provided by users – e.g. technical documentation, manuals, measurement results and certificates which will confirm compliance with the required levels of efficiency and emissions. If users do not have such documents, it will be assumed that the installation does not meet the requirements of the resolution. In case of a breach of the provisions of the resolution, residents can be fined up to PLN 500 or up to PLN 5 000.

What are the differences between boilers that meet the ecodesign requirements and Class 5 boilers?

In both cases, the maximum emission of particulate matter from a boiler during its operation with full power cannot be higher than 40 mg / m³. Eco-designed boilers, on the other hand, ensure that the same emissions are maintained even while operating at lower boiler loads. This is important because boilers seldom run at full power, and at lower loads, burning conditions are worse, resulting in higher particulate matter emissions. Ecodesign requirements also limit the emission of toxic nitrogen oxides from the boiler. It is important that ecodesign requirements have been introduced uniformly throughout the European Union and that since 2020, they will have applied to all of the EU approved boilers. In contrast, the PN-EN 303-5:2012 standard, which specifies the requirements for boilers Class 3, 4 and 5 is a voluntary standard used by some boiler manufacturers only.

Comparison of ecodesign requirements and class 5 according to the PN-EN 303-5:2012 standard

What are coal muds and floatation concentrates?

Coal muds and floatation concentrates are produced by the hard coal processing process through separating the waste rock and other pollutants from the coal mined. As a result, improved coal parameters are obtained, and the coal slurry and coal particles are about 1 mm in size (a limit of 3 mm is adopted in the resolution). This flotation slurry is used to obtain a concentrate with a higher carbon content – carbon floatation and partial evaporation of water produces coal mud. Combustion of both coal mud and floatation results in high emission of pollutants, especially particulate matter, as these are very fine particles, and domestic boilers are not designed to burn them. In addition, they have a high water content, which significantly aggravates the combustion conditions and thus increases the emission of pollutants into the air.

Since July 1, 2017, a resolution of the Sejmik of the Malopolska Region will come into force in the area of Krakow to prohibit the use of the following low-quality fuels (in boilers, stoves, fireplaces):

  • fuels in which the mass fraction of hard coal or lignite of particle size 0-5 mm is more than 5%,
  • fuels containing hard coal or lignite meeting at least one of the following parameters during operation: calorific value below 26 MJ / kg, ash content greater than 10%, sulfur content greater than 0.8%,
  • Fuels containing biomass with moisture content greater than 20%.

Resolution No. XXXV/527/17 of the Sejmik of the Malopolska Region of 24 April 2017 on the introduction in the area of Krakow municipality, in the period from 1 July 2017 to 31 August 2019, prohibitions concerning the scope of operation of installations burning fuel

Since September 1, 2019, only natural gas or light heating oil will be allowed to be used in fuel combustion installations (boilers, ovens, fireplaces). This means banning the use of solid fuels (coal and wood).

Resolution No. XVIII/243/16 of the Sejmik pf the Malopolska Region of 15 January 2016 on the introduction in the area of the municipality of Krakow of restrictions on the operation of installations in which fuel combustion takes place
