🗞️ Driving the news: Scientists have developed a new method to remove carbon dioxide (CO2) from the air, which could aid in reducing atmospheric greenhouse gases. This method uses a CO2-permeable synthetic membrane to capture and concentrate CO2 without requiring significant external energy

🔭 The context: Current methods for CO2 capture are energy-intensive and primarily focus on capturing emissions at the source. The new membrane system leverages energy differences from humidity to drive CO2 capture, presenting a potentially more efficient solution

🌍 Why it matters for the planet: Efficiently removing CO2 from the atmosphere is critical for mitigating climate change impacts. This technology could help in reducing global carbon emissions, aligning with carbon neutrality goals

⏭️ What's next: Further development and testing are needed to evaluate the practicality of this membrane technology outside the laboratory environment. If scalable, it could be integrated into carbon capture and storage systems

💬 One quote: "Our research has shown that a membrane system can remove CO2 from the air, without the need for a large external energy source," said Professor Patricia Hunt

📈 One stat: More than 35 billion tonnes of CO2 are released into the atmosphere annually
