Aviation industry already developing with globalization and as a result of increasing trade volume supports more than 87M jobs direct or indirectly and creates 3.5% of global GDP. Despite to the earnings of sector to economy and tourism annually 915M Tons of CO2 emtitted to nature as 2019. This value represents the 2.5% of total emissions worldwide. In addition to CO2, NOx gases which are also has great harmless effects to the nature also emitted by sector. In order to balance the gas emission rates within the European continent, the European Union Emission Trade Program (EU-ETS) was put into effect by the European Union in 2005, and the system took steps to reduce the carbon emissions of 12,000 energy and production facilities. In 2012, the aviation sector was also included in the program and required the aircraft flying to the European Union countries to enter the carbon commercial system under certain conditions. The International Civil Aviation Organization, alsa has announced a roadmap to keep the emission amounts produced by aviation activities at the international level within the scope of the International Aviation Carbon Equalization and Reduction Scheme (CORSIA) program, which it created in 2016, and it has 4 stages, namely reference determination, pilot implementation, first and second phases. He reported that the scheme will be implemented at the global level.As a result of the CORSIA put into effect by ICAO and the EU-ETS required by the EU, it becomes necessary to keep the carbon reduction or emission rate at a constant level for the continuation of the activities. However, some countries, especially IATA, make reservations for the conditions set and make attempts to postpone the deadline. Airlines, which lost most of their revenues due to the crisis in 2020, were able to receive government and bank aids in return for the support of the European Union Commission, provided that their CO2 rates were reduced. Developing countries object to the strict requirements to be imposed, as the introduction of the carbon reduction scheme will add additional costs for flights. Unlike developed countries such as North America and Europe, China, Middle East Countries, India and Russia argue that sanctions will lead to unfair competition. In order to reduce the emission levels, airlines and manufacturing companies have invested more than $ 1 trillion in more efficient aircraft in the last 10 years, and the industry International Symposium of Scientific Research and Innovative Studies, 22-25 February 2021 2587 has spent 150 billion dollars on R&D activities. The increase in CO2 emissions per kilometer per seat was 22.53%, and 10 new aircraft types were put into service in the past period. Over 270,000 flights have been made using sustainable aviation fuels. The first carbon market pricing mechanism for aviation has been negotiated by the International Aviation Organization (ICAO). In the study, information was given about the position of aviation in the global carbon and other harmful substances emission, the carbon market, the conditions to be put into effect and the measures and road maps that airlines take against these conditions were examined. For this, two carbon reduction programs in force were examined, and the obligations to be brought to aviation companies were included in the study. Finally, due to the low flight levels in 2020 due to the COVID-19 outbreak, the initiatives of Airlines and IATA were conveyed to not be accepted as a reference in carbon reduction rates, and information about the current conditions and future plans of the practices were compiled
