Which countries have NOT agreed to the Kyoto Accord and why they have declined to do so.?

Countries that have not agreed to the Kyoto Accord include the United States and Canada. The U.S. declined to ratify the treaty, citing concerns over its potential economic impact and the exclusion of developing nations from binding commitments. Canada, after initially signing, withdrew from the agreement in 2011, arguing that it would be too costly to meet its targets and that the accord did not adequately address climate change issues. Other nations, like China and India, were not bound by the same commitments due to their developing country status, which has been a point of contention in global climate negotiations.
