Swiss environmental protection expert Stefan Krammer died on Monday in a crash in Switzerland, officials said.
Krammer, 54, who worked for the Swiss Environmental Protection Agency (SEPA), was killed when his private plane crashed in Switzerland’s Languedoc-Roussillon region, the Swiss Federal Aviation Authority said in a statement.
The crash took place at about 11:45 a.m. local time, and Krammers family said he was survived by his wife, his son and his two grandchildren.
Kammer’s work had been crucial to the SEPA, a nonprofit agency tasked with fighting climate change and improving air quality, the agency said.
He was one of the first Swiss citizens to receive an award in 2007 for his work.
He also had been working with the environment and climate change, a Swiss newspaper reported.
Klimmer was a director of the International Institute for Air Transport in Zurich, a university, and also had a doctorate in air transport engineering from the University of Zurich.
He was also a founding member of the World Trade Organization.
He worked as a senior scientist at the Swiss National Institute for Meteorology and Atmospheric Sciences.
His colleagues in Switzerland said he had worked in Switzerland for 30 years, mostly for the SEAPA.
They did not give a reason for the crash.
