Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST research team recalculated climate change and nitrogen pollution using the same standard and found that current carbon emissions already exceed the planet's sustainable limit by more than double.

New Battery Recycling with Carbon Capture Could Make Clean Energy Even Cleaner | Happy Eco News
A new method for battery recycling with carbon capture recovers lithium using carbon dioxide and water while trapping CO₂ and converting leftover metals into catalysts for clean energy technologies.

Direct air capture has substantial health and climate opportunity costs - Communications Sustainability
Renewable energy remains more cost effective for climate and health outcomes than direct air capture except under highly optimistic technology improvements, according to cost equivalent modeling across twenty two United States grid regions

Rising carbon dioxide levels now detected in human blood
Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially relevant for children and adolescents, whose developing bodies will experience the longest cumulative exposure to rising atmospheric CO₂.

Keeping an eagle eye on carbon stored in the ocean
Geologic reservoirs that trapped petroleum for millions of years are now being repurposed to store the greenhouse gas carbon dioxide. New research is improving how we monitor this storage and verify how much CO2 these reservoirs have stored.

Turning CO₂ from urban waste into useful consumer products
EU researchers are turning carbon emissions from urban waste into everyday household products—from cleaning liquids to leather. Europe's cities emit huge amounts of greenhouse gases into the atmosphere. Two essential urban services—waste incineration and wastewater treatment—are among the biggest contributors to municipal CO2 emissions in the EU.

University of Houston’s Carbon Capture Breakthrough Cuts Costs, but Scale Remains Uncertain | Happy Eco News
The University of Houston’s carbon capture researchers achieved 90% CO2 removal at $70 per ton using membraneless technology; however, scaling faces challenges related to cost, policy, and infrastructure.
