Greenhouse emissions
-
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.
-
Making cement is one of the biggest contributors of carbon emissions. Now MIT researchers have developed a new method that can clean up the process.
-
Livestock like sheep and cows are responsible for huge amounts of methane emissions. Now, an international team of researchers has analyzed the gut microbes of different sheep and found clues that may help us curb the problem.
-
A new study has independently measured methane emissions from a number of ammonia fertilizer plants. The startling results suggest methane emissions are 100 times higher than industry estimates, and three times higher than the EPA’s estimate for all industry methane emissions in the United States.

Do meal kits have a larger carbon footprint than regular grocery store shopping? A team of environmental researchers set out to crunch the numbers discovering that despite the extra plastic waste meal kits may produce less environmental emissions than conventional grocery shopping.
-
Bitcoin and other cryptocurrencies have promised a revolution in capital - but at what cost? The Bitcoin network alone is now burning a horrific 240 kilowatt-hours of electricity per transaction, using as much energy as the entire nation of Serbia, and heralding an environmental disaster.
-
Some of the excess carbon dioxide in the air is absorbed by “carbon sinks” like forests and oceans, which helps slow down, but not stop, the greenhouse effect. Unfortunately, a new study has found that oceans are gradually becoming less effective carbon sinks, thanks to rising global temperatures.
-
In the fight to cut greenhouse gas emissions, we tend to think of trees as our allies, but new research suggests they might not be as "green" as we think. Researchers have found that some types of trees emit methane through their trunks, partly countering their role as a greenhouse gas sink.
