The Kyoto Protocol is an international agreement signed by various countries and is associated with option 1 - Clean Environment and Climate Change. This protocol was established in 1997 as an addition to the United Nations Framework Convention on Climate Change (UNFCCC) and aimed to address the issue of greenhouse gas emissions. The goal of the Kyoto Protocol was to reduce the global emission of greenhouse gases, particularly carbon dioxide, in order to combat climate change. It set specific targets and commitments for participating countries to reduce their emissions. The protocol also established mechanisms such as emissions trading and clean development projects to assist countries in achieving their targets. It is important to note that while the Kyoto Protocol was an important step in addressing climate change, it has since been replaced by the Paris Agreement in 2015.
