如果要实现到2020年将碳排放量减少70%的目标，我们可能还要关注以下三个方面：提高能源利用效率，减少森林砍伐和使用低碳能源，这包括核能源和可再生能源。
Perhaps the most interesting fact to emerge is that fully 70% of the reductions needed by 2020 can be achieved by investing in three areas: increasing energy efficiency, reducing deforestation, and use of lower-carbon energy sources, including nuclear and renewables.
