The EU's Carbon Border Adjustment Mechanism (CBAM) doesn't just curb carbon leakage. It may recruit other countries into carbon pricing!🤝 A new #JAERE paper finds the CBAM cuts EU leakage from 40% to 15%. 📊 #JaereFigureFriday 📈📉 #Econsky
A waterfall plot. It consists in a big black bar on the left side (initial emissions), with
smaller bars stacked side by side showing changes in emissions in each country compared to the baseline. The small bars cumulate to another bar on the right, which shows the emissions in the counterfactual emissions. A horizontal line shows how much emissions are reduced in the coalition countries (EU, Canada, Japan, Korea, Taiwan) compared to the baseline (953 MtCO2) and another line shows how much emissions are reduced in total (691 MtCO2). The difference between these two numbers correspond to the contribution of non-coalition countries to the change in emissions (691).

Russia acquired Western weapons components post-sanctions via 3 channels: gradual introduction of restrictions, goods transiting through Russia, or rerouted goods. L Scheckenhofer @feodorateti.bsky.social @torundavid.bsky.social @joschkawanner.bsky.social cepr.org/voxeu/column... #EconSky
The figure shows monthly Russian imports of 42 military-relevant product categories from the EU Common High-Priority list, total and decomposed by channel, using Russian customs transaction data and authors’ coding of EU export bans. Dark red: products not yet subject to any ban. Light red: partially banned products (some product variants are banned but others remain legal to export). Dark grey: in-transit flows with EU as both origin and dispatch country. Light grey: fully banned products rerouted via third countries (non-EU dispatch country).

Despite comprehensive export sanctions from Western allies against Russia, Western components continue to appear in Russian weapons. This column uses transaction-level Russian customs data combined with novel data on EU export bans to separate and quantify three distinct channels through which banned military-relevant goods reached Russia. Trade continued legally for nearly two years, as restrictions were gradually introduced. Furthermore, goods could claim to transit through Russia en route to other destinations or they were rerouted through intermediary countries. It argues that the design and implementation of export bans deserve at least as much attention as their announcement.

Die geplante Finanzierung der #Gasspeicherumlage aus dem #KTF (TSP Background) entspricht einer Senkung des effektiven CO2-Preises auf Gas um 16 Euro. Größte Ironie: mit Einnahmen aus CO2-Preis bzw. dem Sondervermögen (das in den KTF fließen soll) wird nun fossile Energie subventioniert.
