The ocean serves as a vital ecosystem for sustaining life on earth and ensuring human well-being. Presently, there is a significant surge in global demand for various ocean-based economic activities, including fishing, shipping, offshore wind energy production, maritime tourism, and so on. However, this growth has also resulted in an increase in emissions from marine sectors, which have not been thoroughly evaluated or analyzed. It is therefore necessary to conduct comprehensive evaluations of the current emissions, covering marine sectors. To address this need, through this Perspective, we have globally analyzed and discussed carbon emissions linked to maritime transportation, marine capture fisheries, marine aquaculture, offshore wind, ocean renewables, and crude oil production. Additionally, we explored country-specific scales for these emissions and discussed points for future research to address the existing gaps. By gaining a better understanding of emissions over the oceans, policymakers could prioritize policy measures for achieving emission reduction goals and promote sustainable ocean development.
海洋是维持地球生命和确保人类福祉的重要生态系统。目前，全球对各种海洋经济活动的需求显著增长，包括渔业、航运、海上风能生产、海洋旅游等。然而，这种增长也导致了海洋部门排放的增加，而这些排放尚未得到充分的评估或分析。因此，有必要对海洋部门的当前排放进行全面评估。为了满足这一需求，通过本观点，我们对与海上运输、海洋捕捞渔业、海水养殖、海上风力发电、海洋可再生能源和原油生产相关的碳排放进行了全球分析和讨论。此外，我们还探讨了这些排放的国家特定规模，并讨论了未来研究的要点，以解决现有差距。通过更好地了解海洋上的排放，政策制定者可以优先考虑采取政策措施来实现减排目标，促进海洋的可持续发展。
