- Plant-based food alternatives could support a shift to global sustainability
Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest an... - Affordable and available technologies can curb rising nitrous oxide emissions
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 exis... - Abandoned mines may be long-term energy storage solutions
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 ...
- Could we cool the Earth with an ice-free Arctic?
The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. IIASA researchers explored strategies for ... - Plants and fungi together could slow climate change
A new global assessment shows that human impacts have greatly reduced plant-fungus symbioses, which play a key role in sequestering carbon in soils. Restoring these ecosystems could be one strategy...
- Removing fossil fuel subsidies will not reduce CO2 emissions as much as hoped
Fossil fuel subsidies amount to hundreds of billions of dollars worldwide, and removing them has been held up as a key answer to climate change mitigation. Unfortunately it is not the silver bullet...
- The costs of phasing down hydrofluorocarbons
The Kigali Amendment of the Montreal Protocol aims to phase down the consumption of hydrofluorocarbons (HFCs), chemicals that have strong global warming impacts. IIASA research provides the first a... - Trade-off between reducing air pollution, but increasing greenhouse gas emissions
Severe air pollution has plagued China's industrial regions in recent decades, a situation that has received worldwide attention thanks to photos of Beijing and other smog-blanketed Chinese cities....
- Clean energy could stress global water resources
Efforts to reduce greenhouse gas emissions in the energy sector could lead to greater pressure on water resources, increasing water use and thermal water pollution. Dedicated adaptation measures wi...
