A regulation allowing for prolonged delays in the remediation of the former Óbuda Gas Factory has been deemed unconstitutional in Hungary. For thirty years, the extent of dangerous pollutants in the soil at the former gas factory site in Óbuda has been known. However, MVM Next, the current owner and legal successor, consistently postponed the removal of these hazardous materials. This protracted delay has raised concerns about potential environmental and health risks to the surrounding area. The recent ruling signifies a legal victory for those advocating for swift and comprehensive cleanup efforts. The decision now compels action to address the pollution at the Óbuda site, potentially setting a precedent for similar cases involving environmental contamination across Hungary. It remains to be seen how quickly MVM Next will proceed with the necessary remediation work.
