Iceland is also moving towards climate neutrality. Iceland generates over 99% of its electricity from renewable sources, namely hydroelectricity (approximately 80%) and geothermal (approximately 20%). No other nation uses such a high proportion of renewable energy resources. Over 99% of electricity production and almost 80% of total energy production comes from hydropower and geothermal. In February 2008, Costa Rica, Iceland, New Zealand and Norway were the first four countries to join the Climate Neutral Network, an initiative led by the United Nations Environment Programme (UNEP) to catalyze global action towards low carbon economies and societies.
