Hu cites the EU as an example. When the Kyoto Protocol was adopted in 1997, signatory nations established carbon reduction targets for 2012. When the UK and Germany achieved their targets in 2005, they forged ahead, setting new, more stringent targets.
他以歐盟為例，1997 年京都議定書出爐後，各國就訂出 2012 年的減量目標，而英、德等國在 2005 年提早達成目標後，還再接再厲朝新訂目標持續衝刺。
