Greenhouse Gas Emissions

According to some estimates, the generation of the heat used to produce traditional portland cement is responsible for 5% to 8% of all human-made CO2 emissions. A new substance known as C-Crete, however, is claimed to be a much greener alternative.

Researchers have harvested hydrogen from waste plastics using a low-emissions method. They say it not only solves environmental problems, but the value of the graphene by-product could offset the costs of producing hydrogen.

Coming as no surprise to the millions who sweltered through a Northern Hemisphere summer, the season that has just passed was Earth’s hottest since records began in 1880. The steamy baton is expected to now be passed on to the Southern Hemisphere.

Move over, cow burps. A team of scientists has shifted gears from the front to the back end of these methane-production powerhouses, using algae to curb gas emanating from their poop. It's a crap gig, but nature's best methane inhibitor is on the job.

The health benefits of a meat-based versus a plant-based diet are often hotly debated. A new study adds another checkmark to the plant-based column though, as it loops in the environmental impacts of choosing paleo or keto diets over veganism.

While crops do sequester some atmospheric carbon dioxide (CO2) via photosynthesis, they could always use a bit of help. California startup Andes is aiming to provide that help, by putting carbon-capturing microbes in the soil of farmers' fields.

Researchers have identified 27 feedback loops demonstrating how one effect of climbing temperatures leads to events that further reinforce global warming and the initial event itself. The findings make immediate climate action even more crucial.

Make all the jokes you want, but the methane emitted in the form of cow burps and farts is actually a major source of greenhouse gas emissions. That could soon change, however, thanks to bacteria found in baby kangaroo feces.

Atmospheric dust can both cool and warm our planet. A new study shows that this dust could be masking the true impact of greenhouse gasses on climate change, and that a shift in the dust quantity could lead to a warming spike.

By using a labeling system, a research team found that it was possible to shift dining choices away from climate-straining red meat consumption and towards more eco-friendly plant-based options.

Hydrogen will be one of humanity's key weapons in the war against carbon dioxide emissions, but it must be treated with care. New reports show how fugitive hydrogen emissions can indirectly produce warming effects 11 times worse than those of CO2.

Carbon dioxide may hog headlines as a climate change villain, but methane is a far more potent greenhouse gas. MIT has now demonstrated a new way to remove methane from the air, even at low concentrations, with a common clay used to make cat litter.
