Greenhouse emissions
-
Researchers have found a way to take waste concrete from demolition sites and turn it into fresh new concrete that has a strength not seen before from such a product. The breakthrough could lead to significant emissions reductions in the building sector.
-
In the latest bid to greenify ammonia production, researchers have built a portable device to cheaply produce ammonia wherever it's needed by simply using air at room temperature and standard atmospheric pressure.
-
Taking a leaf out of the plant book, scientists have used a method not unlike photosynthesis to harness the power of sunlight and turn two destructive greenhouse gases into useful, prized chemicals for renewable fuel and greener manufacturing.
-
Bill Gates has thrown his weight – and his money – behind a startup making a rich, fatty spread akin to butter, using just carbon dioxide and hydrogen. And this is just the start, with milk, ice-cream, cheese, meat and plant oils also in development.
-
Methane has a greenhouse effect 80 times worse than carbon dioxide over a 20-year period, and emissions are skyrocketing even as we start reducing CO2. That makes UCF's new hydrocarbon-capturing, sunlight-powered catalyst a very compelling idea.
-
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.
-
Despite its many advantages, glass has one major Achilles' heel – it’s brittle. Now, engineers at Penn State have developed LionGlass, a new form that's not only 10 times more damage resistant, but requires significantly less energy to manufacture.
-
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.
-
Climate change can feel inevitable, but we’ve stepped up to the challenge before. New modeling shows how bad things would be if CFCs hadn’t been banned decades ago – depleted ozone would've increased UV exposure and stopped plants capturing carbon.
-
The UK government has announced a legally binding commitment to hit a 78 percent emissions reduction target by 2035, as compared to 1990 levels, on the way to net zero emissions by 2050. For the first time, this target includes aviation and shipping.
-
Cattle are a major source of greenhouse gas emissions, mainly due to their methane-loaded burps. A detailed new study has found more evidence that feeding cows a small seaweed supplement can greatly reduce their methane emissions.
-
New analysis has revealed that emissions of methane, a particularly potent greenhouse gas, have now hit record highs, with the surge being driven in large part by increases in the burning of fossil fuels and increasing agricultural activity.
