此前,船舶经纪公司Braemar ACM Shipbroking珀斯分部的分析师阿比那·古普塔(Abhinav Gupta)向ABC确认,42万吨澳大利亚煤碳在今年7月、8月卸货,另外5.5万吨在今年5月装船的煤碳在7月清仓,但他无法确认这些煤炭的用途。
中国今年前三季度对澳洲进口额突飞猛进意味着什么?

Sometimes I encounter 煤炭 = "coal" whereas sometimes I encounter 煤碳 (such as in the above), and I'm not sure if there's a subtle difference here. I don't see 煤碳 in Pleco, so perhaps it's just a typo.

Question: Are 煤碳 and 煤炭 the same thing ("coal")?

Yes, it is a typo. Usually 碳 means chemical element C.

According to《现代汉语规范词典》:

非金属元素,符号C。有两种同素异形体,即晶质碳和非晶质碳。晶质碳有石墨和金刚石,非晶质碳有木炭、煤、焦炭等。化学性质稳定,在空气中不起变化,是构成有机物的主要成分。在工业和医药上用途很广。

You can say that 煤炭 or 煤 is composed of 碳. So It's a typo.
