Which country did not ratify the Kyoto Protocol and was symbolically signatory as of 2005?

• A. Philippines
• B. United States of America
• C. Russia
• D. Australia

Answer: (B)

The key idea is the difference between signing a treaty and ratifying it. A signatory has expressed support, but only a ratifying country is legally bound by the treaty’s obligations. The Kyoto Protocol, adopted in 1997 and entering into force in 2005, required ratification by participating nations to become binding. The United States signed the treaty in 1998 but never ratified it, so it did not become a binding party and was considered a symbolically signatory rather than a full participant by 2005. Russia, by contrast, had ratified in time for the protocol to take effect, and other listed countries had completed their ratifications as well, placing them in the category of states bound by the protocol or no longer in the same non-ratified status. So, the United States fits the scenario of not ratifying while having signed earlier, making it the best answer.
