Poland remains one of Europe’s most coal-dependent economies and opposes stricter green policies and emissions trading. Warsaw is counting on Hungary’s support in these matters, but Hungary’s domestic green policies could overshadow efforts to revitalize the Visegrád Group (V4). A diplomatic breakthrough will be required for Péter Magyar to maintain a green stance and avoid conflict with Poland. The diverging interests present a challenge to regional cooperation on climate issues. Hungary’s internal environmental policies are gaining prominence, potentially shifting its alignment within the V4 framework. This situation necessitates careful negotiation to balance national agendas with broader European environmental goals, particularly concerning emissions reductions.
