In 2009, Portugal launched the Electric Mobility Plan to encourage large-scale use of electric vehicles by 2020. The increase in the share of electric vehicles in the fleet and the achievement of the expected reduction in oil imports will largely depend on timely development of the electricity network and metering infrastructure, as well as on further growth of renewable electricity production. Under the EU burden-sharing agreement to meet the EU Kyoto Protocol target, Portugal is committed to limit its GHG emissions to an average increase of 27% in 2008-12 compared with 1990 levels.
