What nations has been condemned for its failure to ratify the Kyoto protocol on global warning?

The United States has faced significant criticism for its failure to ratify the Kyoto Protocol, which aimed to reduce greenhouse gas emissions. Critics argue that this decision undermined global efforts to combat climate change, as the U.S. is one of the largest emitters of carbon dioxide. Other nations, particularly those within the European Union, have also expressed disappointment over the U.S. stance, highlighting the need for collective international action on climate issues. Additionally, some developing countries have condemned industrialized nations for not taking adequate responsibility in addressing global warming.
