Although the European Union has legislated, set targets, and negotiated internationally in the area of energy policy for many years, and evolved out of the European Coal and Steel Community, the concept of introducing a mandatory common European Union energy policy was only approved at the meeting of the European Council on October 27, 2005 in London. Following this the first policy proposals, Energy for a Changing World, were published by the European Commission, on January 10, 2007. The most well known energy policy objectives in the EU are 20/20/20 objectives, binding for all EU Member States. The EU is planning to increase the share of renewable energy in its final energy use to 20%, reduce greenhouse gases by 20% and increase energy efficiency by 20%. The EU Treaty of Lisbon of 2007 legally includes solidarity in matters of energy supply and changes to the energy policy within the EU. Prior to the Treaty of Lisbon, EU energy legislation has been based on the EU authority in the area of the common market and environment. However, in practice many policy competencies in relation to energy remain at national member state level, and progress in policy at European level requires voluntary cooperation by members states. In 2007, the EU was importing 82% of its oil and 57% of its gas, which then made it the world's leading importer of these fuels. Only 3% of the uranium used in European nuclear reactors was mined in Europe. Russia, Canada, Australia, Niger and Kazakhstan were the five largest suppliers of nuclear materials to the EU, supplying more than 75% of the total needs in 2009. In 2015, the EU imports 53% of the energy it consumes. In January 2014, the EU agreed to a 40% emissions reduction by 2030, compared to 1990 levels, and a 27% renewable energy target, which is expected to provide 70,000 full-time jobs and cut €33bn in fossil fuel imports. The target is ambitious compared to other advanced economies but insufficient to limit warming to well below 2 °C, let alone 1.5 °C, and align with the Paris Agreement. In 2015, the Framework Strategy for Energy Union is launched as one of the European Commission's 10 Priorities. Energy Union The Energy Union Strategy is a project of the European Commission to coordinate the transformation of European energy supply. It was launched in February 2015, with the aim of providing secure,
