问题 China is confident of meeting its 2030 goals for a peak in carbon dioxide______and lifting the share of non-fossil fuel to around 20 percent of energy use.

选项 A、ejections
B、disposals
C、emissions
D、eruption

答案C

解析 句意:中国有信心在二氧化碳排放量达到峰值时,即2030年,实现目标,将非化石燃料能源消耗的比例提高到20%左右。carbon dioxide emission是固定短语,表示“二氧化碳排放”。因此本题应选C项。ejection喷出;排出物。disposal处置,处理,安排。eruption爆发,喷发。
