What specific environmental violations are Chinese EV and battery companies like CATL and BYD accused of in Hungary?

CATL is under investigation for a suspected pollution incident in May when a greenish liquid bubbled up around its Debrecen plant; the company acknowledged its contractor improperly discharged water colored with a non-toxic substance during a storage tank leak test into the sewer system. BYD is facing a police probe for allegedly illegally moving toxic soil from its Szeged construction site to an outside location—a breach of its environmental permit, according to Environment Minister Laszlo Gajdos.

How has Hungary’s policy shift toward Chinese EV investments changed under Prime Minister Peter Magyar compared to Viktor Orban’s administration?

Under Magyar, Hungary is introducing the strictest environmental rules in the EU, ending lavish tax breaks for multinationals and hiking levies on polluters—marking a sharp departure from Orban’s 16-year rule, which included scrapping the environment ministry in 2010 and enabling lax enforcement that allowed Chinese firms like CATL and BYD to benefit from generous subsidies; Magyar explicitly stated there is 'no compromise' on environmental compliance, even for Chinese industrial interests.
