Cement built the modern world, but it also quietly helped heat the planet. As researchers race to cut emissions from ...

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 ...

A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of 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 ...

GENEVA (AP) — Heat-trapping carbon dioxide levels in the atmosphere jumped by the highest amount on record last year, soaring to a level not seen in human civilization and "turbo-charging" the Earth's ...

Carbon dioxide emissions from human activities and wildfires rose last year, while the land and oceans’ ability to absorb carbon diminished, leading to a record surge in the amount of the ...

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 ...
