Aviation carbon emissions are not too high, but the quantities grows fast and the emissions will conduct at high altitudes. Therefore, the aviation industry has become a key area of global carbon emission reduction. The EU Directive 2008/101/EC is one step ahead in aviation carbon emission reduction, but there are legal defects from the perspective of international conventions, thus the directive makes slow pro gress. ICAOs international aviation carbon offset and emission reduction plan also faces many obstacles. but it will be implemented in 2021.China should seize the opportunity to promote the development of do mestic legal system for aviation carbon emission reduction and strive for the say in the world. On the one hand,China should make basic laws on climate change, incorporate carbon tax into the scope of environ mental protection tax, and promote the legalization of carbon emissions trading, so as to lay the institu tional foundation for aviation carbon emission reduction legal system; on the other hand, China should fo cus on designing and promoting the development of aviation low-carbon technologies and operations, rea sonably allocating quotas for aviation carbon emissions and forming a legal framework for aviation energy prices based on carbon emissions trading.
