A new report published by Nature Communications, is underscoring the importance of a globally holistic approach to climate change mitigation by diving into the interplay between land-based carbon dioxide removal (CDR) technologies and international emissions trading. In researching this interaction — focusing specifically on bioenergy with carbon capture and storage (BECCS) and afforestation/reforestation (A/R) — the study found that these two strategies are mutually reinforcing, with international trading unlocking the geographic potential of CDR and vice versa.
Key points of the study include:
Mutual reinforcement of CDR and trading: CDR and international emissions trading complement each other; international emissions trading significantly increases CDR deployment, while CDR makes it easier for countries to engage in trade as they approach net-zero emissions targets. Regions that lack cost-effective CDR options can rely on emissions trading, while CDR enables some regions to retain positive emissions by offsetting them elsewhere.
Regional Differences: The availability and cost-effectiveness of CDR technologies vary widely by region, and trading allows regions with higher CDR potential to contribute more to global goals.
Economic Efficiency: When both CDR and emissions trading are utilized, the global economy performs better, with more efficient spending and higher GDP.
Technology Deployment: A/R typically deploys earlier due to lower costs but is limited by available land. BECCS, while more costly, offers indefinite CO2 removal over time, making it essential in the long run.
Impact on carbon markets: The presence of international trading expands the potential for CDR deployment and vice versa. Regions with cheaper CDR options can generate revenue by selling emissions permits, which further incentivizes investment in these technologies.
In summary, the report underscores the importance of integrating CDR and emissions trading in climate strategies, highlighting that a well-coordinated approach can optimize both economic and environmental outcomes in the pursuit of net-zero targets.

💡 The findings demonstrate that international carbon markets, including those under Article 6 of the Paris Agreement, are crucial for achieving climate targets. By allowing regions with higher CDR potential to sell into markets where either these solutions are more expensive or not possible, incentivizes greater deployment of CDRs than would have incurred otherwise at a lower overall cost.
💡 This analysis emphasizes the interconnectedness of climate strategies, showing that a holistic approach incorporating both CDR and emissions trading can drive more effective and sustainable decarbonization.
