A unilateral tax on CO2 emissions may drive up indirect carbon imports from non-committed countries, leading to carbon leakage. Using a gravity model of carbon trade, we analyze the effect of the Kyoto Protocol on the carbon content of bilateral trade. We construct a novel data set of CO2...

So-called virtual water, the water "embedded" in internationally traded goods, has come under discussion. The amount of quantitative studies which attempt to estimate volumes and flows of virtual water in relation to agricultural trade is rising rapidly, while the concept has been recognized by...

The European Commission’s (EC) proposed Carbon Border Adjustment Mechanism (CBAM) is meant to mirror the carbon price of the EU Emissions Trading System (EU ETS) for several imported goods. While the CBAM can rely on certain aspects of the EU ETS regarding its costs and compliance obligations,...

The European Emissions Trading System (EU ETS) constitutes a central European climate policy instrument. Since its start of operation in 2005, the carbon market has grown considerably in terms of trading volume and also with regard to the various players being active. This report is part of the...

In addition to carbon dioxide, air traffic operation affects the climate through other emissions and atmospheric processes, such as the formation of ozone and contrail cirrus. The climate impact of these non-CO2 effects is strongly dependent on the emission location (in particular cruise...

For years, humans have been trying to stabilize the world's environment by lowering the amount of greenhouse gases that their societies pump into the air. In 1992, this approach was even incorporated into the UN Framework Convention on Climate Change. But because this strategy failed to produce...

Achieving the Paris Agreement Long-term temperature goal (PA LTTG) requires closing the 2030 ambition and action gap between emissions levels consistent with the Paris Agreement and emissions levels projected with current targets and policies. G20 countries have a crucial role to play in...

A broad range of mitigation options have been identified and assessed in the literature that enable countries to close the existing gap between 2030 emission projections resulting from the aggregate efforts of countries to achieve their Nationally Determined Contributions to the Paris Agreement...
