Accelerating the performance of our industrial customers - Conscious of the planet s limits, SUEZ has made a commitment to the circular economy, delivering solutions to reduce and recover its customers industrial waste, reuse treated water and reduce their carbon footprint.

The concept of planetary boundaries Formulated by an international team of 28 researchers led by Johan Rockström from the Stockholm Resilience Centre, the nine planetary boundaries are the thresholds that humanity must not exceed to avoid compromising the favour- able conditions under which it has devel- oped, and to be able to live sustainably within a safe ecosystem.

The authors consider that the thresholds have already been crossed for three of the seven boundaries for which they pro- pose limit values, in terms of volumes emitted or extracted from the environ- ment (climate change, biodiversity loss and disruption to the nitrogen and phos- phorus biochemical cycles).
