Although widely recognized as imperative for reducing global emissions and the amount of waste generated by the architecture, engineering, and construction (AEC) sector, a large-scale shift from a linear to a circular economy has not yet happened in practi ...
To curb the severe effects of climate change, our society needs to radically reduce its CO2 footprint. For the heavy-duty sector, where electrification is difficult, alternative fuels can be the solution. Methane-fueled engines have lower energy-specific C ...
Wildfires are a significant source of organic aerosol during summer, with major impacts on air quality and climate. However, studies in Europe suggest a surprisingly low (less than 10%) contribution of biomass burning organic aerosol to average summertime ...
Protozoa comprise a major fraction of the microbial biomass in the rumen microbiome, of which the entodiniomorphs (order: Entodiniomorphida) and holotrichs (order: Vestibuliferida) are consistently observed to be dominant across a diverse genetic and geogr ...
This commentary paper from the recently formed International Global Atmospheric Chemistry (IGAC) Southern Hemisphere Working Group outlines key issues in atmospheric composition research that particularly impact the Southern Hemisphere. In this article, we ...
Negative emissions are necessary on the path to net-zero. This short presentation shows how they contribute to climate neutrality and how that could be paid for. ...
How effective has past Swiss climate policy been in lowering CO2 emissions, in particular the CO2 levy? Finding that they have been little effective, what innovative instruments could be more effective, in particular for aviation? ...
Why focus on action levers? • Wellbeing with low energy demand is clearly defined in low energy scenarios like LED or DLS, but it is far from obvious how to get there, including even collectively deciding on what is a good transition. • Progressively chang ...
Aerosols play an important yet uncertain role in modulating the radiation balance of the sensitive Arctic atmosphere. Organic aerosol is one of the most abundant, yet least understood, fractions of the Arctic aerosol mass. Here we use data from eight obser ...
What would it take for aviation to become climate-neutral by 2050? We develop and model a trajectory for aviation to reduce its CO2 emissions by 90% by 2050, down to a level where all residual emissions can be removed from the atmosphere without crowding o ...
