为了保证非能源消费导致的二氧化碳的排放量低于4000亿吨，减少森林砍伐和土地利用变化等因素导致的温室气体排放将很有必要。
To keep these emissions below 400bn tons, complementary reductions in emissions from deforestation and land use change, as well as other greenhouse gases, will also be necessary.
在这种情况下，2010年至2050年间，全球能源消费导致的二氧化碳排放总量累计将达到约12000亿吨，剩下约4000亿吨的指标用于非能源消费导致的温室气体排放。
In this scenario, cumulative energy-related carbon dioxide emissions between 2010 and 2050 would total about 1, 200bn tons, leaving about 400bn tons for non-energy-related greenhouse gas emissions.
要完成到2020年我国非化石能源在能源消费总量中所占比例达到15%的目标，任务非常艰巨。
China's objective is to raise the share of non-fossil energy in its energy mix to 15% by 2020. This objective is very difficult to achieve.
