Madrid city council has ratified a 55-point plan to combat greenhouse gas emissions and promote sustainable energy usage. Approved measures include the establishment of an alternative fuel network, an energy efficiency rating for businesses and buildings and the planting of 1.5 million trees. The initiative should reduce greenhouse gases by 14 per cent compared to 2004 levels over the next five years, with Madrid emitting just over 13 million tons of polluting gases in 2012, nearly two million below the Kyoto Treaty target of 15 million tons.
