CSG is committed to providing energy efficiency solutions for home and business owners globally with the goal of preventing dangerous anthropogenic (i.e., human-induced) interference of the climate system. We support the Kyoto project initiative and are proud members of the US Green Building Council. The Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) is an international treaty that sets binding obligations on industrialized countries to reduce emissions of greenhouse gases. According to the UNFCC website, the Protocol "recognizes that developed countries are principally responsible for the current high levels of GHG emissions in the atmosphere as a result of more than 150 years of industrial activity, and places a heavier burden on developed nations under the principle of 'common but differentiated responsibilities." There are 192 parties to the convention, including 191 states (all the UN members, except Andorra, Canada, South Sudan and the United States) and the European Union. The United States signed but did not ratify the Protocol and Canada withdrew from it in 2011.The Protocol was adopted by Parties to the UNFCCC in 1997, and entered into force in 2005.
