Are sustainable aviation fuels truly sustainable?

24-Jul-2024 - A new IIASA-led study offers the first detailed estimates of land use change emissions for six sustainable aviation fuel production pathways. The authors focused on both food and non-food raw materials used to produce biofuels, using trusted global data sources to provide fine-scale emissions ...

Affordable and available technologies can curb rising nitrous oxide emissions

07-Jul-2023 - Researchers from IIASA and the University of Maryland in the US have found that nitrous oxide, a potent greenhouse gas and stratospheric ozone-depleting substance, could be readily abated with existing technology applied to industrial sources. When greenhouse gases are released into the ...

Turning abandoned mines into batteries

A novel technique turns decommissioned mines into long-term energy storage solutions, thereby supporting the sustainable energy transition

16-Jan-2023 - Renewable energy sources are central to the energy transition toward a more sustainable future. However, as sources like sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. While there are many effective solutions ...

Lazy microbes are key for soil carbon and nitrogen sequestration

03-Dec-2015 - The world's soils store on the order of 2500 gigatons of carbon, which is three times the amount in the atmosphere (or equivalent to 9170 gigatons of CO2). Yet the mechanisms behind this storage are not completely understood. A new study, published in the journal Nature Communications, shows that ...

Carbon sequestration in soil

The potential underfoot

21-Oct-2015 - A new study projects that carbon sequestration in European cropland could store between 9 and 38 megatons of carbon dioxide (Mt CO2) per year in the soil, or as much as 7% of the annual greenhouse gas emissions from agriculture in the European Union, at a price of carbon of 100 $/tCO2. “However, ...
