T1 Involvement of Aviation Activities in the Scheme for Greenhouse Gas Emission Allowance Trading JF Transactions on Transport Sciences YR 2009 VO 2 IS 2 SP 42 OP 47 DO 10.5507/tots.2009.008 UL https://tots.upol.cz/artkey/tot-200902-0002.php AB The European Union includes the Environment as one of the four main target areas requiring greater effort. One pillar of EU environmental policy is the Greenhouse Gas Emission Trading System. In the EU directive 2008/101 it was held that aviation will be added to the system of greenhouse gases trading. Despite the relatively low volume of aviation emissions, the danger of aviation emissions emitted in the higher atmosphere tips the scales. Aviation will be part of the ETS from year 2012, but the most important decisions and customizations of the ETS system for aviation are to be done now. The involvement of aviation in the ETS presents many difficulties and problems, which need to be solved to allow the ETS to bring benefits to both aviation and the whole of society as well.
