Johan Rockström (born 31 December 1965) is a Swedish scientist, internationally recognized for his work on global sustainability issues.

He is joint director[1] of the Potsdam Institute for Climate Impact Research (PIK) in Germany, together with economist Ottmar Edenhofer.

The nine planetary boundaries presented in the framework, from climate to biodiversity, are argued to be fundamental in maintaining a "safe operating space for humanity.

[8] In 2010, the magazine Miljöaktuellt ranked him the second most influential person in Sweden on environmental issues, and Veckans Affärer gave him its "Social Capitalist Award".

In 2009, Rockström led an international group of 28 leading academics, who proposed a new Earth system framework for government and management agencies as a precondition for sustainable development.

[28] delimited by the planetary boundaries safeguards the stable environmental conditions that made the emergence of modern societies possible in the first place and will allow coming generations to develop and thrive.

They then estimated how much further we could go before the risk of "irreversible and abrupt environmental change" which could make Earth less habitable increases.
