Carbon flows at neighborhood scale Case study in Geneva, Switzerland

Sophie Lufkin, Ulrich Joseph Jacques Liman

In a context of political commitment targeting net zero in 2050, controlling carbon flows is an essential operational imperative. The LOCUS methodology (Low carbon urban strategy) makes it possible to establish an exhaustive vision of carbon flows at neigh ...

Net Zero and Carbon Removal without Greenwashing

Sascha Nick

What happens when companies falsely make climate action claims? The best way to avoid litigation risks is genuine climate action, but does it mean in practice? What is the link of avoidance and removal offsets, voluntary and compliance markets, and net zer ...

The mesoglea buffers the physico-chemical microenvironment of photosymbionts in the upside-down jellyfish Cassiopea sp.

Anders Meibom, Niclas Heidelberg Lyndby, Michael Kühl

IntroductionThe jellyfish Cassiopea has a conspicuous lifestyle, positioning itself upside-down on sediments in shallow waters thereby exposing its photosynthetic endosymbionts (Symbiodiniaceae) to light. Several studies have shown how the photosymbionts b ...

Paying for negative emissions

Philippe Thalmann

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. ...

Swiss Negative Emissions Fund - paying for Net Zero

Sascha Nick

We propose setting up a public polluter-financed fund to pay for the removal of all Swiss territorial GHG (greenhouse gas) emissions from 2030. The fund will accelerate decarbonization and help reach annual net zero emissions around 2040, and then progress ...

Carbon removal, net zero, and implications for Switzerland

Philippe Thalmann, Sascha Nick

Carbon removal, including carbon capture, utilization and storage (CCUS) and negative emission technologies (NET), is an important but small part of climate action, unlikely to scale beyond 5-10% percent of current emissions, in the 2-3 critical decades we ...

Flexibility for large-scale deployment of PV systems in low-voltage grids

Jordan Holweger

To meet the net-zero emission target by 2050, Switzerland must install between 34 and 50 GW of distributed photovoltaic (PV). The inherent challenge with such an extensive integration of stochastic generation is to provide the flexibility for balancing sup ...

High‐resolution spatial sampling identifies groundwater as driver of CO 2 dynamics in an Alpine stream network

Tom Ian Battin, Amber Joy Ulseth, Asa Lovisa Viktoria Horgby, Marta Boix Canadell

Inland waters are major sources of CO2 to the atmosphere. The origin of this CO2 is often elusive, especially in high‐altitude streams that remain poorly studied at present. Here we study the spatial and seasonal variations in streamwater CO2, its potentia ...

Non-ablative femtosecond laser exposure of fused silica in the sub-50 fs regime (Conference Presentation)

Yves Bellouard, Erica Kathleen Block

In the non-ablative regime, femtosecond laser pulse duration is known to affect the nature of the modification induced in the microstructure of fused silica. It has been demonstrated than below 200 fs, two different regimes are found, one at low energy, le ...

Decentralized clustering over adaptive networks

Ali H. Sayed, Ali Zoubir

Cooperation among agents across the network leads to better estimation accuracy. However, in many network applications the agents infer and track different models of interest in an environment where agents do not know beforehand which models are being obse ...
