New Report Analyzes The Role Of Carbon Removal In Achieving Net Zero Emissions

New Report Analyses The Role Of Carbon Removal For Achieving Net Negative Emissions - Carbon Herald

A new report is kick-starting the new year with an investigation of applying carbon dioxide removal (CDR) to achieving the long-term goal of the Paris Agreement of limiting global warming. 

The report called The role of carbon dioxide removal in contributing to the long-term goal of the Paris Agreement examines best practices in implementing CDR and offers four scenarios contrasting carbon removals and emission reductions to demonstrate effects on net global emissions.

The analysis is commissioned by the Swedish Energy Agency and authored by Kenneth Möllersten (IVL), project leader, Johannes Bednar (International Institute for Applied Systems Analysis, IIASA), Eve Tamme (Climate Principles), Robert Höglund (Marginal Carbon), Michael Obersteiner (Environmental Change Institute at University of Oxford).

Via this report, the Swedish Energy Agency (SEA) aims to translate the Article 6 of the Paris Agreement into action. Achieving the long-term temperature target of the Paris Agreement requires the balancing of both greenhouse gas emissions reductions and carbon removals which combined should result in net zero or net negative emissions.

Carbon market instruments, including Article 6, have the potential to contribute to the development of carbon removal activities. The successful implementation and execution of a net zero or net negative emissions strategy requires careful planning and execution in terms of timing and the role these collaborative instruments will take. 

The report: 

  • Investigates best practices in the implementation of the collaborative instruments under Article 6 for the incentivization and scaling of carbon removal. 
  • Discusses the need to assign responsibility for climate overshoot reversal to guarantee the viability of a global net-negative GHG economy. 
  • Analyzes and proposes ways to address risks associated with carbon removal, including mitigation deterrence, re-released of CO2, carbon-leakage effects, and challenges related to monitoring mitigation outcomes. 
  • Proposes four illustrative climate mitigation scenarios that show the long-term effect on net global emissions under different combinations of implementation between CDR and emission reductions. 
  • Offers recommendations.

The least climate overshoot is achieved in the climate mitigation scenario called Proactive Transition. It includes reliance on primary energy substitutes like nuclear, non-biomass renewables and biomass to displace fossil fuels. Parallel to this, policies aiming to cut back on final energy consumption are assumed to deliver tangible results. 

The role of carbon removal is also recognized in the near-term to minimize short-term overshoots and the deployment of substantial amounts of carbon removal is implemented. However, the short-term push associated with building the CCS infrastructure integrates in the longer-term with bioenergy generation (resulting in BECCS), fossil fuel processes, and various hard-to-abate industrial applications, which also means prolonging their use.
