The EU has proposed four flexibility mechanisms for the regulation of greenhouse gas emissions in the period 2013-2020: (1) the Emissions Trade Scheme (ETS), a permit market between selected companies; (2) trade in non-ETS allotments between Member States; (3) the Clean Development Mechanism...

The current EU proposal on greenhouse gas emission reduction has 28 targets for 2020: an EU-wide one for carbon dioxide emissions covered by the European Trading System, and one target for non-ETS emission per Member State. Implementation is necessarily more expensive than needed. I consider...

Carbon dioxide emissions are a major force driving climate change. We construct scenarios of CO2 emissions from fossil energy until 2100 in Europe. Major innovations are first that economic growth is based on an endogenous economic growth model and second that we calibrate our model to...

We use a model of international and domestic tourist numbers and flows to investigate the effect of various climate policy instruments implemented in Europe on arrivals and emissions for the countries concerned. We find that these schemes do not fulfil their desired effects. The introduction of...

We examine the impacts of the EU-US Open Skies agreement on the environment, in particular looking at the effect of the agreement on emissions from the aviation sector. We use the Hamburg Tourism Model, a model of domestic and international tourist numbers and flows, to estimate these impacts....

A simulation model of international tourist flows is used to estimate the impact of including carbon dioxide emissions from aviation fuels in the European Trading System. The effect on global carbon dioxide emissions from international aviation is minimal: -0.01% at current permit prices, and...
