Klemeš’s name appeared in the prestigious Highly Cited Researchers ranking last year, as well as in 2018 and 2020. The ranking is created by analysts selecting one percent of the most cited scientific articles in individual fields over the last ten years from the Web of Science database. For the year 2022, ten researchers who belong to Czech institutions appeared in the list.

Klemeš had extensive foreign experience, spending years at universities in Great Britain, Hungary or China. In 2017, he returned to the Brno technical school, which he once studied, and built his own team focused on sustainability. People with various specializations were represented in it.

“Whatever you do, you must always consider energy, water, emissions, waste and the impact on society. That is why we also have experts in geography or history in our team. An exceptional scientific article then provides a certain overlap and is interesting both for the broad scientific community and for society,” said Klemeš last year.

One of his successful professional texts was an article on the effects of the covid-19 pandemic on the environment. “I realized how huge the amount of single-use plastics and waste is related to healthcare. And the pandemic has increased this burden even more. My colleagues and I calculated the impact the pandemic had on our waste management, and we proposed six possible directions of research aimed at mitigating the potential impact of covid on this area,” said Klemeš at the time.
