Carbon capture and conversion must not rely on rare metals

Last year, humans emitted approximately 37 billion tonnes of carbon dioxide into the atmosphere – a disastrous and unsustainable figure. To avoid the worst effects of climate change we could capture some of that carbon ...

Scientists turn carbon emissions into usable energy

A recent study affiliated with UNIST has developed a system that produces electricity and hydrogen (H2) while eliminating carbon dioxide (CO2), the main contributor of global warming. This breakthrough has been led by Professor ...

Sewers could help clean the atmosphere

Sewage treatment—an unglamorous backbone of urban living—could offer a cost-effective way to combat climate change by flushing greenhouse gases from the atmosphere.

New report examines key steps in removing carbon dioxide from air

Peter Kelemen is a geologist and the Arthur D. Storke Memorial Professor at Lamont-Doherty Earth Observatory. A member of the National Academy of Sciences (NAS) and an expert in carbonation of rock from Earth's mantle, Kelemen ...

Powder could help cut CO2 emissions

Scientists at the University of Waterloo have created a powder that can capture CO2 from factories and power plants.
