Strategies for the Evaluation and Assessment Of Ocean based Carbon Dioxide Removal

SEAO2-CDR是一个雄心勃勃的多学科项目，将科学、经济、法律、政治、社会和伦理方面的专家研究人员与行业领袖和监管机构联合起来，建立和评估可持续和有效运作海洋二氧化碳清除(OCDR)所需的评估路径和方法。实施适当的CDR战略被认为是大多数净零排放路径的重要组成部分，但促进这些战略部署所需的机制和进程在很大程度上仍未得到探索。值得注意的是，与地面CDR技术相比，OCDR方法通常受到的关注较少，尽管提供了同等或更大的封存潜力。SEAO2-CDR解决了我们对典型的OCDR方法的技术经济理解方面的关键空白，以确定它们在环境和经济上可行的作业空间，并将使用最先进的地球系统模型(ESM)和自主传感器技术为不同的方法建立强大的监测、报告和核查(MRV)战略。将制定以利益攸关方为导向的治理框架，确定多层面的互动点，通过这些互动点，可以对对外合作伙伴进行负责任和有效的治理，并支持扩大对外合作伙伴关系所需的业务发展和投资。最后，生态协同效应的参数化和系统层面的权衡将使OCDR能够被纳入综合评估模型(IAM)，该模型确定哪些技术最适合支持向气候中立和有弹性的社会的过渡。这些活动将使SEAO2-CDR能够通过支持环境安全、社会可接受和经济上可行的有助于实现全球气候政策的方法的特征和开发，来推进OCDR的实施潜力。

SEAO2-CDR is an ambitious multidisciplinary project that unites expert scientific, economic, legal, political, social and ethical researchers with industry leaders and regulators to establish and assess the evaluation pathways and methodologies required for sustainable and effective operationalisation of Ocean-based Carbon Dioxide Removal (OCDR). The implementation of appropriate CDR strategies is regarded as an essential component of most Net Zero emission pathways, yet the mechanisms and processes needed to facilitate their deployment remain largely unexplored. Notably OCDR approaches have generally received less attention than terrestrial CDR technologies despite offering equivalent, or greater, sequestration potential. SEAO2-CDR addresses critical gaps in our technoeconomic understanding of archetypal OCDR approaches in order to define the operational spaces in which they are environmentally and economically viable, and will establish robust Monitoring, Reporting and Verification (MRV) strategies for different approaches using state-of-the-art Earth System Models (ESMs) and autonomous sensor technologies. Stakeholder-oriented governance frameworks will be developed that define the multi-dimensional interaction points through which responsible and effective governance of OCDR could be implemented and support the business development and investment needed to scale up OCDR. Finally, the parameterisation of ecological synergies and system-level trade-offs will enable OCDR to be incorporated into Integrated Assessment Models (IAMs) that identify which techniques are best positioned to support the transition to a climate-neutral and resilient society. Together these activities will enable SEAO2-CDR to advance the implementation potential of OCDR by supporting the characterisation and development of environmentally safe, socially acceptable, and economically viable approaches that can help realise global climate policies.
