🗞️ Driving the news: French start-ups and researchers are testing the country’s first direct air capture (DAC) prototypes to remove CO₂ directly from the atmosphere
• Yama, a Paris-based start-up, has deployed a 3.5-meter-high pilot unit in Drancy, which has run for 1,500 hours and captured 1.3 metric tons of CO₂
• Although the technology is operational, the captured gas is currently released back into the air as the focus remains on validating safe and effective capture

🔭 The context: DAC technologies are part of “negative emissions” solutions intended to complement emissions reductions and help meet climate targets
• France is investing in early-stage pilots to test their viability
• Experts warn that DAC remains energy-intensive, costly, and unproven at scale, with questions over efficiency, long-term storage, and economic feasibility

🌍 Why it matters for the planet: If scaled effectively, DAC could remove greenhouse gases from the atmosphere, directly reducing net CO₂ concentrations and helping limit global warming
• However, current limitations mean its impact is modest, and it cannot replace immediate emissions cuts from energy, industry, and transport sectors

⏭️ What’s next: Researchers aim to refine chemical solvents, improve energy efficiency, and test permanent storage options
• Policymakers and investors are watching for cost reductions and scalable designs that could enable DAC to contribute meaningfully to France’s climate strategy and Europe’s broader negative emissions goals

💬 One quote:
“At this stage, the main goal is to demonstrate that it works safely.” — Valentin Fougerit, cofounder and CEO of Yama
