The Kyoto Protocol is an international agreement to reduce greenhouse gas emissions. It set targets for industrialized countries to cut emissions by 5% below 1990 levels by 2008-2012. Each country agreed to its own target, such as an 8% cut for EU countries. The protocol went into legal effect in 2005 after Russia ratified it. However, countries are not on track to meet targets and the US withdrawal was a major setback. The Copenhagen Summit in 2009 aimed to forge a new agreement to replace Kyoto but only produced the non-binding Copenhagen Accord, continuing pressure for countries like the US to pass emissions legislation.
