Abstract: Based on the present international situation that the EU’s policy for imposing carbon emission tax on international aviation will take effect formally, the evolution and specific policies are introduced, and methods for monitoring carbon emissions as well as the international influences are discussed. EU aviation carbon tax might increase the costs of global aviation, and ultimately will be transferred to consumers. EU aviation carbon tax will have little effect on the airline companies of developed countries, but much effect on those of developing countries. It is recommended that China should develop related standards for carbon emissions as soon as possible, so as to safeguard the rights of development and speaking.

Key words: EU, aviation carbon tax, carbon emissions, emission allowance
