“We are the first generation to know we are undermining the life-support systems of our planet—and the last that can still do something about it.”

Current Role
Director of the Potsdam Institute for Climate Impact Research (PIK), professor in Earth System Science, and one of the world’s leading sustainability scientists.

Notable Achievement
Rockström is co-creator of the “planetary boundaries” framework, which defines nine critical Earth system processes that regulate the stability of our planet. This concept has become one of the most influential scientific models for understanding the limits of human activity.

His view on what is happening now
Johan Rockström warns that humanity is already transgressing several of the nine planetary boundaries, including climate, biodiversity, and land use. In his analysis, this puts us at risk of destabilizing the Earth system itself, moving us away from the safe operating space in which civilizations have thrived for 10,000 years. He describes our current trajectory as a “planetary emergency” driven by fossil fuel dependence, deforestation, and the relentless overuse of natural resources.

According to Rockström, the failure of political and economic systems to act with the necessary speed and scale has made the 2020s the decisive decade. Without urgent transformation, feedback loops—such as ice sheet melting, forest dieback, or ocean acidification—could trigger irreversible shifts in the Earth system.

His long-term solutions
Rockström calls for a global transformation that respects planetary boundaries while ensuring human well-being. This means decarbonizing energy systems, restoring ecosystems, redesigning food production, and embedding sustainability into economic and political decision-making. He emphasizes the need for science-based targets for companies, nations, and institutions, aligned with the resilience of the Earth system.

In the long term, his vision is one of a regenerative, carbon-neutral global economy operating within safe ecological limits. He stresses that the challenge is not only technical but deeply political: societies must reframe prosperity away from short-term growth and toward stability, resilience, and fairness.
