After ten years of promises, the authorities of Bosnia and Herzegovina still don't tell the people who pollutes the air in their towns

17.6.2021 - ZENICA / PRAGUE

The air in Bosnia and Herzegovina belongs among the dirtiest in Europe (1) and in 2020, it was ranked tenth for PM2.5 pollution worldwide (2). Despite that, citizens still have a hard time trying to understand who is responsible. Although the state authorities have been obliged to collect and publish the data on pollution since 2003, they have not been able to launch an adequate system so far. The non-governmental organizations Arnika (Czechia) and Eko forum Zenica (Bosnia and Herzegovina) published top ten largest polluters for 2018 (3) based on the available data. They urge the governments to ensure access to information from all large industries.

Not surprisingly, large factories that are usually considered as the culprits of pollution lead  the top tens for 2018: ArcelorMittal Zenica, the Tuzla, Ugljevik, and Gacko thermal power plants, the Lukavac and Kakanj cement kilns, the GIKIL coke plant, and the refinery in Slavonski Brod. Arnika and Eko forum Zenica have been publishing the data collected from the state authorities since 2011. For the first time, the alternative database shows industries from both entities of the country.

“There was a slight improvement in the data transparency by 2019, as the annual emission reports are finally publicly available online (4). However, the official websites are not user-friendly and only experts can understand what the numbers represent. That is why we interpret the data and believe that the public will use it to act against the polluters and the authorities. Without public demand, the environmental conditions will never improve,” Samir Lemeš from Eko forum Zenica explains.

A comparison of the data from the last decade enables us to recognise which companies invest in modernization and technologies to protect the environment and human health. A decrease in the pollution from the Ugljevik coal power plant was caused by investment into desulphurization in 2019. The emissions of ArcelorMittal Zenica also decreased, but it was caused by the drop in production related to the global economic crisis; the citizens of Zenica are still waiting for modernization. 

Some of the largest polluters are still hiding their environmental footprint – such as the coal power plant in Kakanj. While in the EU, coal power plants report emissions of about 15 pollutants, Bosnian plants – such as the Gacko coal power plant – publish data only on three to five basic chemicals. For example, information on releases of heavy metals, which represent serious threats to human health, is missing entirely.

The analysis of Arnika and Eko forum Zenica shows that the data submitted by the Industrial companies is not reliable and contains a huge amount of errors; almost 90% of the data is irrelevant. Moreover, the entities of Bosnia and Herzegovina operate different systems using different methodologies. 

“Although Bosnia and Herzegovina signed the PRTR Protocol (5) in 2003, the parliaments did not ratify it till today. Thus, the system is not obligatory for industries. Transparency of data on pollution is a key step on the way to cleaner air. Without access to information, the state authorities cannot act. The public and the media are not able to control the situation, and the polluters can continue with business as usual at the expense of the environment and public health,” Martin Skalsky, an expert on public participation from Arnika, says.

For comparison, in Czechia, 1,334 facilities reported emissions in 2018 and the reports included 35 pollutants into air and others into soil, wastewater, and waste, while in the Federation of Bosnia and Herzegovina it was only 19 air-polluting substances (6) and in the Republika Srpska only six chemicals. The situation is not improving and the number of substances reported is basically the same today as it was back in 2011.
