The big problems, of course, are how we take account of past responsibility for the carbon in the atmosphere, how we balance aggregate national emissions and per capita figures – China leads in the first category; the US, Australia, and Canada are the biggest culprits in the second – and how we manage technology transfer from developed to emerging and poor economies. There will be plenty to moan about if we don’t solve these problems sooner rather than later.
而其中很明显存在几个重大问题，包括探讨各国如何为过去排放到大气中的碳负责，还有如何在国家总排放量和人均排放量间取得平衡——中国在总排放量方面占的比重很大；而美国，澳大利亚和加拿大则在人均排放量上成为了不好的榜样——以及如何去实现由发达国家向新兴及贫穷国家的技术转让。如果我们不尽快解决这些问题，那将来可就有足够多的东西要抱怨的了。
