China’s carbon dioxide (CO2) emissions fell by 1% in the final quarter of 2025, likely securing a decline of 0.3% for the full year as a whole. This extends a “flat or falling” trend in China’s CO2 ...

Chinese scientists have found a way to recycle lithium batteries using only carbon dioxide and water – eliminating the need for harsh, polluting chemicals to extract the lithium and upcycle cathode ...

One of the most important measurements we make while tuning an engine is finding out what the actual balance of air and fuel was inside the engine. It doesn’t matter if we have a carburetor, port ...

If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard the term “wideband O2 sensor” being thrown around at the track, dyno ...

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 ...

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 ...

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 ...

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 ...

Scientists have developed a material with photosynthetic bacteria that convert carbon dioxide into a mineral skeleton. The material hardens over time, so it could be used for buildings, they say. When ...

Earth’s atmosphere now has more carbon dioxide in it than it has in millions — and possibly tens of millions — of years, according to data released Thursday by the National Oceanic and Atmospheric ...

Atmospheric CO 2 levels have increased as a result of anthropogenic activities. This rise has contributed to global warming, ocean acidification, and the degradation of ecosystems. Addressing this ...
