Kyoto Protocol

An international treaty intended to combat global warming that limits the amount of greenhouse gases that nations may emit. Every major country in the world has ratified the Kyoto Protocol except the United States (which never ratified it) and Canada (which withdrew in 2011). The treaty was signed in 1997 and came into effect in 2005.
