Global Environmental Agreements and International Trade: Asymmetry of Countries Matters [PDF]

open access: yes, 2014
We investigate the formation of global climate agreements (= stable grand climate coalitions) in a model, in which climate policy takes the form of carbon emission taxation and fossil fuel and consumption goods are traded on world markets.

Spatial distribution of Δ14CO2 across Eurasia: measurements from the TROICA-8 expedition [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Because fossil fuel derived CO2 is the only source of atmospheric CO2 that is devoid of 14C, atmospheric measurements of Δ14CO2 can be used to constrain fossil fuel emission estimates at local and regional scales. However, at the continental scale,

Lewis‐Acid Engineering with Neodymium Promoters as Synergistic Nd‐Ni Dual Sites for Enhanced Urea Oxidation

open access: yesAdvanced Science, EarlyView.
The integration of rare‐metal neodymium centers to engineer Lewis acid sites with nickel centers is proposed as highly efficient UOR catalysts. ABSTRACT The sluggish kinetics of the urea oxidation reaction (UOR) are strongly associated with the high energy barriers required for the C‐N cleavage and N‐N coupling steps.

A Chinese Sky Trust? Distributional Impacts of Carbon charges and Revenue Recycling in China [PDF]

open access: yes
The introduction of carbon charges on the use of fossil fuels in China would have a progressive impact on income distribution. This outcome, which contrasts to the regressive distributional impact found in most studies of carbon charges in industrialized
