🗞️ Driving the news: Experts warn that carbon dioxide removal (CDR) remains too slow to significantly offset global emissions
• Despite growing awareness, current CDR initiatives capture only about 5% of annual CO₂ emissions, mostly through natural methods like reforestation
• Advanced techniques such as biochar production, biomass capture, direct air capture (DAC), and ocean-based solutions are still in early, costly stages

🔭 The context: The third edition of “The State of Carbon Dioxide Removal” was presented in Milan by scientists from the U.S., Germany, China, and Australia
• CDR differs from conventional carbon capture at power plants by targeting CO₂ already in the atmosphere
• Growth is limited by high costs (often >$200 per ton), land competition, and insufficient investment
• Last year, only 2 million metric tons of CO₂ were removed out of over 40 billion tons emitted globally

🌍 Why it matters for the planet: Without scaling CDR, atmospheric CO₂ levels will continue rising, driving climate change impacts such as heatwaves, sea-level rise, and biodiversity loss
• While emission reductions remain the primary tool, carbon removal is essential for offsetting residual emissions, meeting net-zero targets, and avoiding the most severe climate consequences

⏭️ What’s next: Scientists urge immediate investment and government support to expand CDR technologies
• Early adoption by private companies can demonstrate viability, but large-scale deployment will require public funding and policy frameworks to treat carbon removal as a public good
• The coming years are critical for scaling these solutions to meaningful levels

💬 One quote: “We can have companies who are playing this important early role but in the long term we’re going to need governments to be buying this public good.” – Morgan Edwards, University of Wisconsin-Madison

📈 One stat: Current CDR initiatives remove 2 million metric tons of CO₂ annually, compared with over 40 billion tons emitted by humans
