Novel Carbon Dioxide Removal Approaches Emerge as Key to Achieving Paris Agreement Temperature Targets

Strategic Insights -

Research funded by Csiro's Carbonlock Future Science Platform and Csiro's Responsible Innovation Future Science Platform has been undertaken to develop novel carbon dioxide removal (CDR) approaches that can assist in achieving the Paris Agreement temperature targets. The study, conducted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), has identified the importance of considering local stakeholders' perspectives when deploying these technologies, particularly in specific locations. The researchers employed a bottom-up engagement approach, interviewing 23 stakeholders in Tasmania, Australia, and found that local stakeholders are concerned with impacts beyond their immediate area.

Key Takeaways:

  • The study identified the need for more information regarding technological feasibility, environmental and community impacts, governance, and the role of ocean alkalinity enhancement (OAE) in climate policy.
  • Stakeholders expressed a need for knowledge priorities to be addressed before social acceptance consultations, highlighting concerns beyond local impacts.
  • The research concluded with four guiding principles for responsible CDR innovation and deployment: accountability, sustainable resource management, transparent governance, and inclusive values and ethics.
  • The study emphasizes the importance of involving local stakeholders in the decision-making process and considering their perspectives when deploying CDR technologies.
  • The qualitative analysis conducted by the researchers aimed to provide a deeper understanding of stakeholders' perspectives and knowledge priorities.

Statistics:

  • 23 stakeholders were interviewed in Tasmania, Australia, as part of the research.
  • Four guiding principles for responsible CDR innovation and deployment were identified: accountability, sustainable resource management, transparent governance, and inclusive values and ethics.
  • The study found that stakeholders' knowledge priorities should be addressed before social acceptance consultations.
