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 aviation into the European Trading system results in a fall in the number of tourists travelling into the EU in favour of other destinations. It also causes a significant welfare loss with only a small reduction in emissions. The flight taxes in the Netherlands and the United Kingdom result in different substitution effects across destinations (depending on the zones being taxed) but both policies do have the same consequence of inducing welfare losses and also reducing visitor numbers to the countries. We find that when these policies are combined their effects are additive. Welfare impacts are robust to variations in the underlying assumptions and changes in the scope of the taxes examined have the expected effects.

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. The Open Aviation Area will result in increased competition between carriers and consequently falls in the cost of transatlantic flights. This will not only have implications for the size and structure of the industry but also for climate policy. The objectives of this paper are (1) to assess what effects the expected increases in passenger numbers will have on CO2 emissions and (2) to test whether this increase in travel will result in a corresponding rise in emissions. Model simulations show that passenger numbers arriving from the US to the EU will increase by between 1% and 14% depending on the magnitude of the price reductions. We find that because of substitution between destinations, the percentage increase in global emissions is much smaller (max. 1%) than the increase in cross-Atlantic traffic. In the current context of greenhouse gas control policies, any increase in emissions will make climate policy objectives more difficult to achieve and will attract more attention to aviation's contribution to climate change.

We use a model of domestic and international tourist numbers and flows to estimate the impact of the EU-US Open Skies agreement that is to take effect in March 2008. The Open Aviation Area will result in increased competition between transatlantic carriers and consequently falls in the cost of flights, therefore we look at the change in visitor numbers from the US into the EU and corresponding CO2 emissions. We find that passenger numbers arriving from the US to the EU will increase by approximately 1% and 14% depending on the magnitude of the price reductions. This increase in passenger numbers does not however result in a corresponding rise in emissions as arrivals into other countries from the US fall by a comparable amount. The number of tourist arrivals from the US to countries outside of the EU will fall and overall emissions would then increase by a maximum of 0.7%. If we assume that domestic holidays and foreign holidays are close substitutes these effects are strengthened and US passengers switch from domestic trips to foreign destinations as airfares converge.

The purpose of this study is to check the monetary value of the recreational use of Irish forests using two different valuation methods on the one dataset - the Travel Cost Method and the Contingent Valuation Technique - and in doing so test convergent validity, i.e. whether they are consistent with each other. It is found that convergence cannot be established with this data. The Willingness-to-Pay for entrance responses are stationary and tend to cluster around IR£1 per adult equivalent per trip. The TCM results of consumer surplus, which should be the same as WTP, are more variable depending on which sample is analysed and range between IR£2.38 and IR£5.95 per adult equivalent per trip. No correlation between these two variables was found. It seems that there are problems in getting people to state their true WTP. This is possibly due to a misinterpretation of the question by respondents as well as a tendency to revert to a common number. It is also likely that respondents used their WTP answers to make a political statement against the expansion of forestland using agricultural land. Finally, forests in Ireland are regarded as public goods and consequently there exists a stance among users that access to them should be free of charge, which might explain the large number of protest bids.
