At the meetings of the International Civil Aviation Organization in Montreal on October 4, the ICAO approved what they called an historic framework agreement, authorizing the development of global market-based measures to curb greenhouse gas emissions over the next three years, for implementation in 2020. The resolution encourages nations to develop new aircraft technology, adopt carbon-dioxide standards and use sustainable alternatives to jet fuels. By rejecting a European Union proposal to include aviation in the EU emissions trading system immediately, the ICAO drew criticism from green groups who criticize the slowness of the 2020 start date.
