China has begun commercial operation of a power generation system that uses carbon dioxide instead of steam, marking the first real-world deployment of the technology. On Dec. 20, a supercritical CO2 ...

A joint research team has developed a highly efficient photocatalyst that can convert carbon dioxide into the high-value-added fuel, methane, using sunlight, while explaining its operating principles.

A laboratory setup shows yellowish and bluish light from two lamps shining on a metallic reactor. Deep-ultraviolet, infrared, and visible light shine on carbon dioxide and methane in a reactor, ...

China has launched the world’s first carbon dioxide–based power generator, using supercritical CO2 instead of steam to produce electricity with over 50% efficiency. The system harnesses industrial ...

The projected rise in CO2 emissions in 2025 is driven by growth in coal, like the coal-fired plant pictured, as well as oil and gas, according to the 2025 Global Carbon Budget Report. Global carbon ...

Surging emissions from wildfires may have been behind the increase, which was the largest since modern measurements began more than half a century ago. By Raymond Zhong and Sachi Kitajima Mulkey The ...

Greenhouse gas concentrations increased by a record amount in 2024 as more carbon dioxide, methane and nitrous oxide became locked in Earth's atmosphere, a World Meteorological Organization report ...

Atmospheric carbon dioxide levels jumped by a record amount in 2024 to push concentrations to their highest point since measurements began, the UN’s World Meteorological Organization (WMO) has ...

Not-so-fun fact: our oceans hold 150 times more carbon dioxide than the Earth's atmosphere. Adding to that causes ocean acidification, which can disrupt marine food chains and reduce biodiversity.

Experts estimate that the global production and disposal of plastics emits nearly 2 billion tons of greenhouse gases per year. The vast majority of these materials end up in landfills, but what if we ...

The award-winning science writer Peter Brannen makes the case for an often vilified compound in “The Story of CO2 Is the Story of Everything.” By Jaime Green Jaime Green is the author of “The ...

Is carbon dioxide a pollutant? A small but vocal group of researchers, authors and government officials say it is time to change the definition. Greenhouse gases including CO2 are considered air ...
