The February-March stay in Greece was an opportunity for me to delve into different approaches to environmental and energy regulation. I used the time in Greece for the needs of my research on the Industrial Emission Directive (Directive 2010/75/EU on industrial emissions (integrated pollution prevention and control)). Apart from it I had the interesting academic discussions on the EU energy and environmental law with the Greek colleagues and students as well as met the Polish exchange students at the National and Kapodistrian University of Athens.
