Summary of the Final Report: "Current understanding of the potential impacts of Carbon Dioxide Removal approaches on the SDGs in selected countries in Latin America and the Caribbean"

Core Content

This report provides an analysis of the potential impacts of Carbon Dioxide Removal (CDR) approaches on the Sustainable Development Goals (SDGs) in selected countries in Latin America and the Caribbean (LAC), specifically focusing on Argentina and Colombia. It also includes a broader regional perspective on CDR technologies and their implications for climate change mitigation and sustainable development.

Main Viewpoints

The study aims to:

• Identify and characterize the current status of knowledge on CDR approaches and their impacts.
• Analyze the sequestration capacity and potential economic, social, and environmental impacts of CDR technologies in selected countries.
• Evaluate the compatibility of CDR approaches with the SDGs and national climate strategies.

The report outlines the following key CDR approaches:

1. Afforestation and Reforestation – Planting forests to store carbon in biomass.
2. Bioenergy with Carbon Capture and Storage (BECCS) – Using biomass for energy and capturing CO2 emissions.
3. Enhancing Soil Carbon Content with Biochar – Producing biochar from biomass and using it to enhance soil carbon.
4. Enhanced Weathering or Ocean Alkalinization – Accelerating the natural weathering of rocks or adding minerals to the ocean to absorb CO2.
5. Direct Air Carbon Dioxide Capture and Storage (DACCS) – Capturing CO2 directly from the atmosphere.
6. Ocean Fertilization – Adding nutrients to the ocean to stimulate phytoplankton growth, thereby removing CO2 from the atmosphere.

The report notes that while these approaches are considered in the analysis, CDR methods involving building materials or industrial processes are excluded.

Key Information

1. Current Status of Knowledge and Development

• Argentina:

  • A detailed review of the status of knowledge and development for each CDR approach is provided.
  • Data includes current projects, installed capacity, and trends in biomass and biogas.
  • Information on the legal and policy framework, including regulations and programs, is outlined.
  • Examples of initiatives like Renovar are highlighted, showing the scale of biomass and biogas projects.

• Colombia:

  • Similar analysis is conducted, with a focus on afforestation, mangrove restoration, and bioenergy projects.
  • The report includes data on mangrove areas, species composition, and restoration potential.
  • It also outlines current and projected bioenergy and biochar capacities, as well as employment and economic trends.

• LAC Countries:

  • The report includes a broader regional overview of CDR approaches, highlighting areas where research is more developed.
  • It provides insights into the potential for afforestation, bioenergy, biochar, and enhanced weathering across the region.

2. Impact Analysis

• Methodology:

  • The impact analysis is based on a set of key indicators: employment, GDP, costs, GHG emissions, and SDG achievement.
  • Scenarios are developed to project the future implications of CDR adoption, including growth rates, investment levels, and CO2 sequestration potential.

• Argentina:

  • Afforestation and Reforestation: Projected to increase cultivated forest area, with potential to reduce GHG emissions and support SDGs 1 (No Poverty), 8 (Decent Work and Economic Growth), and 13 (Climate Action).
  • BECCS: Expected to reduce emissions and contribute to SDG 13. It also has potential to support SDG 8 through job creation in the bioenergy sector.
  • Biochar: Can enhance soil carbon, support SDG 15 (Life on Land), and has potential to reduce emissions and improve agricultural productivity.

• Colombia:

  • Afforestation and Reforestation: Similar potential for GHG reduction and SDG 15 support.
  • Mangrove Restoration: Offers significant carbon sequestration potential, supports SDG 13 and 15, and could also help with coastal protection and biodiversity.
  • BECCS: Has the potential to reduce emissions and support SDG 13, with opportunities for integration with existing bioenergy infrastructure.
  • Biochar: Can improve soil quality, reduce emissions, and support SDG 15 and 8.

• LAC Countries:

  • The potential impacts of CDR approaches on the SDGs are summarized, with emphasis on the role of afforestation, bioenergy, and biochar in supporting sustainable development and climate mitigation.

3. Limitations of the Analysis

• The study acknowledges the uncertainty surrounding the efficacy and feasibility of many CDR technologies.
• There are knowledge gaps in understanding the long-term impacts and scalability of these approaches in the LAC region.
• The economic and social implications of CDR adoption require further research to fully assess.
• The geopolitical and regulatory challenges of implementing large-scale CDR projects are noted as potential barriers.

4. Recommendations

• Governments in the LAC region should prioritize research to better understand the impacts and feasibility of CDR approaches.
• Incentivize and govern the adoption of CDR technologies in national climate strategies.
• Integrate CDR approaches with existing sustainable development goals and NDCs.
• Support green recovery plans by incorporating CDR technologies as part of broader climate and development strategies.

Conclusion

The report highlights the potential of CDR approaches to contribute to climate change mitigation and the achievement of the SDGs in the LAC region. However, it also emphasizes the need for further research, policy development, and investment to ensure that these technologies are implemented in a way that is both effective and sustainable. The focus on Argentina and Colombia provides a detailed understanding of the current state of CDR knowledge and development, while the regional overview offers a broader context for future action.
