《碳通訊》的目標是成為一本全面涵蓋碳材料和富碳分子的雜志。這些材料的范圍從金剛石和石墨到焦碳、半焦碳、中間相物質、碳纖維、碳納米管、石墨烯、炭黑、活性炭、熱解碳、玻璃狀碳等。利用上述各種碳材料二次生產新型碳及復合材料的論文屬于該期刊的研究范圍。只有當研究與生成的碳材料密切相關時，才會考慮有關有機物(包括煤)的論文。《碳通訊》還力求跟上其專業領域的新發展，并聯合起來為當前的問題，如溫室效應和臭氧層損耗，尋找替代能源的解決辦法。可再生能源基礎、能源儲存與轉化、太陽能、風能、水能、核能、生物質能源、制氫技術等清潔能源技術也在該期刊的范圍內。《碳通訊》誠邀各界人士就碳科學與技術的理論與實踐領域的基礎研究發表原創報告。

Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
