The Kyoto Protocol is an international agreement linked to the United Nations Framework Convention on Climate Change, with the goal of achieving stabilization of greenhouse gas concentrations in the atmosphere. It commits state parties to reduce greenhouse gas emissions to levels below 1990 emissions between 2008-2012. Key sectors of concern are energy supply, industrial processes, waste management, and land use. The Protocol calls for domestic policies and measures like improving energy efficiency and promoting renewable energy to achieve emission reduction targets, though some issues around developing nation commitments and funding remain unresolved.
