This book is devoted to the The Kyoto Protocol which is a significant protocol to the international Framework Convention on Climate Change with the objective of reducing greenhouse gases that cause climate change. It was adopted on 11 December 1997 by the 3rd Conference of the Parties, which was meeting in Kyoto, and it entered into force on 16 February 2005. As of June 2008, 182 parties have ratified the protocol. Of these, 36 developed cg countries (plus the EU as a party in its own right) are required to reduce greenhouse gas emissions to the levels specified for each of them in the treaty (representing over 61.6% of emissions from Annex I countries), with three more countries intending to participate. One hundred thirty-seven (137) developing countries have ratified the protocol, including Brazil, China and India, but have no obligation beyond monitoring and reporting emissions. "The Kyoto Protocol" separates countries into two groups. Annex I includes developed nations, while Non-Annex I refers to developing countries. Emission limitations are only placed on Annex I countries. Non-Annex I nations participate by investing in projects that lower emissions in their own countries. For these projects, they earn carbon credits. These credits can be traded or sold to Annex I countries, which allow them a higher level of maximum carbon emissions for that period.
