Air transport, like every economic branch, strives for development. Air traffic is growing dynamically, which means that the natural environment is increasingly being polluted each year. Therefore, entities operating in the air transport sector should care for the environment. One of these entities - airports - introduces many restrictions for aircraft with high CO2 (carbon dioxide) emissions. At the same time, they introduce many ecological activities. Every year, also at the largest Polish airports, managers carry out activities aimed at caring for the environment. The main goal of the article is to evaluate the implementation of ongoing projects related to environmental protection at selected Polish airports. For this purpose, a survey was conducted at Polish airports in March 2020. The main research thesis is that as a result of the development of air traffic, airports will start investing more in innovative solutions related to environmental protection, including solar panels. This issue is extremely important from the point of view of economic, environmental, and corporate social responsibility. The main problems of the environmental policy are areas related to waste, water, and energy management. Some airports take up challenges related to the implementation of innovative solutions, including sustainable energy management. Tasks related to reducing energy consumption and increasing the use of green energy at airports will be of key importance.
