With a global policy framework adopted at the 37th ICAO Assembly in October 2010, international aviation is the first sector with a shared global agreement to environmental goals of increasing 2% annual fuel efficiency and stabilizing its global CO2 emissions at 2020 levels. ICAO and its 191 Member States, in cooperation with industry, have been making further progress on actions requested by the Assembly, in order to move international aviation closer to a sustainable future.
Greenhouse gas emission from international shipping is modest but steadily growing apace with globalization and world trade. Therefore, IMO has been energetically pursuing control of GHG emissions from international shipping through a global approach, in recognition of the magnitude of the climate change challenge. As a result, mandatory measures to reduce GHG emissions from international shipping were adopted at IMO, in July 2011, constituting the first global CO2 reduction regime for an international industry sector.
