Addressing the Concerns About Carbon Leakage in the Implementation of Carbon Pricing Policies : a Focus on the Issue of Competitiveness

Rey, Florian ; Madiès, Thierry

In: Journal of Industrial and Business Economics, 2021, vol. 48, p. 53-75

This article investigates whether the implementation of asymmetric carbon pricing policies leads to carbon leakage. We first present the theoretical mechanisms behind carbon leakage. Secondly, we conduct a review of the existing empirical results of carbon leakage. We focus on the competitiveness channel and therefore rely on papers analysing the effects of asymmetric carbon prices on both...

Spatial and temporal analysis of meso- and microplastic pollution in the Ligurian and Tyrrhenian Seas

Caldwell, Jessica ; Muff, Livius F. ; Pham, Christopher K. ; Petri-Fink, Alke ; Rothen-Rutishauser, Barbara ; Lehner, Roman

In: Marine Pollution Bulletin, 2020, vol. 159, p. 111515

Areas like the Mediterranean coastlines, which have high population density, represent locations of high pollution risk for surrounding environments. Thus, this study aims to compare data on the abundance, size, and composition of buoyant plastic particles collected during two weeks in 2019 in the Ligurian and Tyrrhenian Seas with data from 2018. The results from 2019 show average meso- and ...

Rapid genomic and phenotypic change in response to climate warming in a widespread plant invader

Sun, Yan ; Bossdorf, Oliver ; Grados, Ramon D. ; Liao, Zhi, Yong ; Müller‐Schärer, Heinz

In: Global Change Biology, 2020//n/a/-

Predicting plant distributions under climate change is constrained by our limited understanding of potential rapid adaptive evolution. In an experimental evolution study with the invasive common ragweed (Ambrosia artemisiifolia L.) we subjected replicated populations of the same initial genetic composition to simulated climate warming. Pooled DNA sequencing of parental and offspring...

Genetic structure of the endemic Papaver occidentale indicates survival and immigration in the Western Prealps

Pittet, Loïc ; Fragnière, Yann ; Grünig, Sandra ; Bétrisey, Sébastien ; Clément, Benoît ; Gerber, Emanuel ; Ronikier, Michał ; Kozlowski, Gregor ; Parisod, Christian

In: Alpine Botany, 2020, p. -

Climatic oscillations of the Quaternary rapidly compelled plant species to shift their geographical range. How alpine plant species responded to climate change, however, remains elusive and remnants of the cold-adapted flora that currently strive in restricted ranges as small, isolated populations have been particularly overlooked. To address the evolutionary history of such a ‘glacial...

Cold-water coral mound archive provides unique insights into intermediate water mass dynamics in the alboran sea during the last deglaciation

Fentimen, Robin ; Feenstra, Eline ; Rüggeberg, Andres ; Vennemann, Torsten ; Hajdas, Irka ; Adatte, Thierry ; Van Rooij, David ; Foubert, Anneleen

In: Frontiers in Marine Science, 2020, vol. 7, p. -

The Alboran Sea is widely recognized to host numerous cold-water coral ecosystems, including the East Melilla Coral Province. Yet, their development through time and response to climatic variability has still to be fully understood. Based on a combined investigation of benthic foraminiferal assemblages, foraminiferal stable isotope compositions, grain size analysis, sediment geochemistry, and...
