While the regulatory mechanisms of both Kyoto and the European Trading Scheme have contributed to the establishment of an emerging market for carbon trading, interested parties are now concerned about the immediate future. Without a regulatory framework beyond 2012, the window of opportunity for initiating project-based transactions will close by 2006/2007.
京都议定书和欧洲贸易计划的调节机制促进了日益兴起的碳贸易的确立，使得有兴趣的政党现在开始对不久的将来表示担忧。若2012年后还没有一个管理框架出台，那么创立一个项目式交易的机会之窗将在2006或2007年之前关闭。
