The bloc's environment ministers were meeting in Brussels to discuss deforestation-free imports.
Greenpeace often goes big when it comes to protests, and it was no different in Brussels on Thursday.
Climbers from the organisation scaled the EU Council's Europa building -- where environment ministers from the 27 member states were meeting to discuss deforestation-free imports -- placing a banner highlighting how many hectares of forest were destroyed as talks went on.
Greenpeace says Brussels is wasting time by talking and must act quicker.
