The Headquarters of Greenpeace International is located in

Static-GK ‘headquarters’ questions test the city that hosts an organisation's central secretariat or registered international office — this is a fixed factual detail, separate from where a body was originally founded or where it runs the most field operations.

Greenpeace International, the coordinating body for the worldwide Greenpeace network, has its global secretariat based in Amsterdam, Netherlands. (Note: Greenpeace itself was founded in Vancouver, Canada, in 1971, but the International's headquarters/secretariat is in Amsterdam — founding city and headquarters city are not always the same.)

• New York hosts the headquarters of several major global bodies, most notably the United Nations — a frequent source of confusion, but Greenpeace International's own secretariat is not based there.

• Sydney is home to a national/regional Greenpeace office (Greenpeace Australia Pacific), which coordinates work within that region rather than serving as the International's global secretariat.

• Nagasaki is historically significant as the site of the 1945 atomic bombing and features in anti-nuclear discourse that Greenpeace often campaigns on, but the city itself hosts no Greenpeace organisational headquarters.
