SEAO2-CDR

SEAO 2-CDR是一个雄心勃勃的多学科项目，将科学、经济、法律的、政治、社会和伦理方面的专家研究人员与行业领导者和监管机构联合起来，建立和评估可持续和有效实施海洋二氧化碳去除（OCDR）所需的评估途径和方法。实施适当的CDR战略被认为是大多数净零排放途径的重要组成部分，但促进其部署所需的机制和流程在很大程度上仍未得到探索。值得注意的是，尽管有机碳减排方法具有同等或更大的固碳潜力，但其受到的关注通常少于陆地碳减排技术。SEAO 2-CDR解决了我们对原型OCDR方法的技术经济理解方面的关键差距，以确定它们在环境和经济上可行的操作空间，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方法建立强大的监测，报告和验证（MRV）战略。将制定面向利益攸关方的治理框架，确定多层面互动点，通过这些互动点，可以对减灾办公室进行负责任和有效的治理，并支持扩大减灾办公室规模所需的业务发展和投资。最后，生态协同作用和系统级权衡的参数化将使OCDR能够被纳入综合评估模型（IAM），以确定哪些技术最适合支持向气候中立和有弹性的社会过渡。这些活动将使SEAO 2-CDR能够通过支持环境安全、社会可接受和经济上可行的方法的特点和发展来推动OCDR的实施潜力，这些方法可以帮助实现全球气候政策。

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 techno economic 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.
