Life cycle assessment integration into energy system models: An application for Power-to-Methane in the EU

François Maréchal, Victor Codina Gironès

As the EU energy system transitions to low carbon, the technology choices should consider a broader set of criteria. The use of Life Cycle Assessment (LCA) prevents burden shift across life cycle stages or impact categories, while the use of Energy System ...

Dissolved major and trace geochemical dynamics in Antarctic lacustrine systems

Tyler Joe Kohler

Clearwater Mesa Uames Ross Island, northeast Antarctic Peninsula) provides a unique opportunity to study solute dynamics and geochemical weathering in the pristine lacustrine systems of a high latitude environment. In order to determine major controls on t ...

Des contingents flexibles pour le transport aérien

Philippe Thalmann

L'avion fait croître les émissions de CO2 imputables aux Suisses. La politique envisage une taxe sur les billets. Cet article documente l'évolution des émissions, examine les solutions envisagées et en propose une autre: l'attribution d'un budget à chaque ...

Spatiotemporal Drivers of CO2 Dynamics and Evasion Fluxes from Mountain Streams

Asa Lovisa Viktoria Horgby

Inland waters are key components of the global carbon cycle, emitting a substantial amount of carbon dioxide (CO2) to the atmosphere. Climate change and global warming affect mountain catchments significantly, leading to glacier retreat and changing precip ...

Dynamics and potential drivers of CO2 concentration and evasion across temporal scales in high-alpine streams

Tom Ian Battin, Asa Lovisa Viktoria Horgby, Nicolas Thomas Georges Escoffier, Luis Gómez Gener

Carbon dioxide (CO2) evasion from streams greatly contributes to global carbon fluxes. Despite this, the temporal dynamics of CO2 and its drivers remain poorly understood to date. This is particularly true for high-altitude streams. Using high-resolution t ...

Development of heterogeneous catalytic systems for the transformation of carbon dioxide to methanol under mild conditions

Aswin Gopakumar

Rising level of carbon dioxide (CO2) is a significant contributor to global warming and poses a major concern in modern society and environment. Anthropogenic activities such as fossil fuel combustion, cement production and deforestation are the primary ca ...

Solar-driven reduction of CO₂ : from homogeneous to heterogeneous catalytic systems

Marcel Roland Schreier

Rapidly increasing levels of atmospheric carbon dioxide and their damaging impact on the global climate system raise doubts about the sustainability of the fossil resource based energy system. Meanwhile, raising living standards and increasing global popul ...

How green are British cities? Scaling relations and CO2 emissions

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni

How green or environmentally friendly urban areas are in comparison with rural areas is a topic that has received much attention in recent years. This is understandable because urban areas already emit around 70% of the global greenhouse gases. This percen ...

Direct synthesis of formic acid from carbon dioxide by hydrogenation in acidic media

Paul Joseph Dyson, Gabor Laurenczy, Séverine Joëlle Moret

The chemical transformation of carbon dioxide into useful products becomes increasingly important as CO2 levels in the atmosphere continue to rise as a consequence of human activities. In this article we describe the direct hydrogenation of CO2 into formic ...

The effects of land use and climate change on the carbon cycle of Europe over the past 500 years

Jed Oliver Kaplan, Kristen Marie Krumhardt

The long residence time of carbon in forests and soils means that both the current state and future behavior of the terrestrial biosphere are influenced by past variability in climate and anthropogenic land use. Over the last half-millennium, European terr ...

Impacts of changes in land use and land cover on atmospheric chemistry and air quality over the 21st century

Songmei Wu, Jed Oliver Kaplan

The effects of future land use and land cover change on the chemical composition of the atmosphere and air quality are largely unknown. To investigate the potential effects associated with future changes in vegetation driven by atmospheric CO2 concentratio ...

The prehistoric and preindustrial deforestation of Europe

Jed Oliver Kaplan, Kristen Marie Krumhardt

Humans have transformed Europe’s landscapes since the establishment of the first agricultural societies in the mid-Holocene. The most important anthropogenic alteration of the natural environment was the clearing of forests to establish cropland and pastur ...
