Abstract. There is substantiated the need to modernize the transport area of Ukraine in the view of state obligations adopted during the signing of international environmental agreements. It is argued that the adoption of the United Nations Framework Convention on Climate Change and its further implementation by the Kyoto Protocol and the Paris Agreement require the signatory States to take measures to minimize the anthropogenic impact of CO2 emissions in the earth’s atmosphere. A comparative analysis of the qualitative and quantitative composition of the fleet of transport industries of European countries and Ukraine proves that the minimization of environmental pollution by Ukraine should be done by renewal the fleet. Based on the statistics of the quality fleet of transport industries of European countries that practice CO2 emissions and those that who does not tax harmful CO2 emissions, it is demonstrated the dependence of the age — related conditions of the fleet, where the taxation demonstrates its incentive properties to modernize transport industries and renew fleets to modern vehicles. The characterization of global trends in minimizing of harmful emissions into the atmosphere of greenhouse gases gave a reason to argue that the implementation of an environmental tax has a dual nature. On the one hand, the tax encourages owners of enterprises, institutions, organizations of transport industry to invest in environmentally friendly transport to minimize the tax burden, and on the other hand, the taxation influences on the environmental situation in the regions and on the planet as a whole. It is substantiated that regulations aimed at minimizing harmful emissions into the atmosphere allow at the state level to implement policies on the formation, distribution and use of tax revenues for fighting climate change. It is concluded that tax revenues from the taxation of CO2 emissions into the atmosphere can be used to support the transport industry through public-private partnerships. It also emphasizes that Ukraine should intensify international cooperation and agree with developed countries to support the modernization of the Ukrainian transport industry using financial mechanisms and technology transfer agreements to increase resistance to climate change and reduce greenhouse gas emissions enshrined in the Paris Agreement.
