Putting climate-positive business ideas into practice

Start-ups made carbon-​neutral fuels and turning carbon dioxide into stone

14-Jan-2021

More and more ETH Zurich researchers are taking the plunge into entrepreneurship. By launching spin-​offs, they hope to turn their lab findings into solutions that can help stem the rise in atmospheric carbon dioxide. There is no shortage of evidence for what the Fifth Assessment Report of the ...

NIST Study Identifies Chemical Blends as Possible Alternative Refrigerants

31-May-2019

More than a dozen chemical blends could serve as alternative refrigerants that won’t heat the atmosphere as much as today’s refrigerants do, or catch fire, according to a new computational study by the National Institute of Standards and Technology (NIST). The NIST study identified the 22 “best” ...

Great strides for carbon capture using earth-abundant elements as photocatalytic system

04-Dec-2018

Researchers at Tokyo Institute of Technology have designed a CO2 reduction method based only on commonly occurring elements. Achieving a 57% overall quantum yield of CO2 reduction products, it is the highest performing system of its kind reported to date, raising prospects for cost-effective ...

How biofuels from plant fibers could combat global warming

28-Feb-2018

Scientists, companies and government agencies are hard at work on decreasing greenhouse gas emissions that cause climate change. In recent years, biofuels produced from corn have emerged as a fuel source to power motor vehicles and, perhaps, airplanes. But corn is problematic as a biofuel source ...

Coastal water absorbing more carbon dioxide

02-Feb-2018

As more carbon dioxide enters the atmosphere, the global ocean soaks up much of the excess, storing roughly 30 percent of the carbon dioxide emissions coming from human activities. In this sense, the ocean has acted as a buffer to slow down the greenhouse gas accumulation in the atmosphere and, ...

Measurement of noble gases in Antarctic ice cores

08-Jan-2018

The average sea temperature is an essential parameter of the global climate – but it is very difficult to measure. At least until now, because an international team of researchers including Empa scientists have now developed a novel method using the concentration of noble gases in the eternal ...

Carbon capture is helped by oil revenue, but it may not be enough

30-Nov-2017

The oil industry incentivises the development of carbon-capturing tech, but researchers say this will not reduce emissions to low enough levels. Carbon dioxide can be used to extract oil, accelerating the development carbon-capturing technologies and limiting climate change. However, in a new ...

Huge carbon sink in soil minerals

09-Nov-2017

A Washington State University researcher has discovered that vast amounts of carbon can be stored by soil minerals more than a foot below the surface. The finding could help offset the rising greenhouse-gas emissions helping warm the Earth's climate. Marc Kramer, an assistant professor of ...

The benefits of waste-to-energy technologies

30-Aug-2017

Instead of hauling food waste to landfills, we might want to use that organic waste to power garbage trucks, your car, truck or SUV while at the same time potentially helping the environment. Organic waste such as yard trimmings, paper, wood and food produces millions of tons of methane emissions ...
