There are still 29 countries which have not yet adopted it. Croatia and Kazakhstan have signed the treaty, but have not ratified it (made it a law they have to follow). Donald Trump and The United States of America has signed it but said that they will not ratify it. Australia has only recently ratified the Kyoto Protocol under the previous Prime Minister, Kevin Rudd. Both of these countries have said that the fact that China and India are using exceptions to the treaty (those countries believe parts of the treaty do not apply to them and they will not follow those parts) in the name of industrialization is unfair and that they will not ratify because of this, although it is believed that the U.S. and Australia are protecting their economic interests by not ratifying. The countries' leaders say that changing their use of greenhouse gases will make their people lose jobs. The twenty four other countries have neither signed nor ratified the treaty.
