Löfstedt grew up in Los Angeles to parents who were professors of medieval languages.^[2] With Swedish and American nationality, he is also fluent in German. He worked as a lumberjack on the family farm in Sweden before attending UCLA. He has a doctorate from the Graduate School of Geography, Clark University, studying with Roger Kasperson (1988-1993).

Löfstedt teaches risk analysis at King's College London. Prior to this, he was a reader at the Centre for Environmental Strategy, University of Surrey where he worked with University of California at Berkeley academic David Vogel. Löfstedt also holds adjunct faculty status at Carnegie Mellon university in the US and Gothenburg in Sweden.^[3] He was at one time adjunct faculty at the Harvard Center for Risk Analysis where he teaches an executive education course.

He has worked mainly on risk communication and management. Studies have included renewable energy policy, transboundary environmental issues (acid rain and nuclear power), health and safety, telecommunications, biosafety, pharmaceuticals, the siting of waste incinerators, fuel policy, nuclear waste installations and railways. He aim is to strengthen proactive risk communication, arguing that high regulatory/industry trust results in low public perceived risk.

Professor Löfstedt was appointed by the UK Coalition Government to look at occupational safety and health and in particular, the bureaucracy faced by those self-employed whose work activities do not pose a risk to others.^[6] The review, officially entitled Reclaiming Health and Safety For All but often referred to as the Löfstedt Report, was published by the Department for Work and Pensions in 2011.^[7]
