Aware of the urgency to act in the face of several issues, each more worrying than the last, we try to adopt the most holistic approaches possible so as not to neglect any aspect of the sustainable transition that we are calling for. For example, in the face of the global problem of climate change, it is essential, in addition to CO2 emissions, to take an interest in other no less important issues such as social justice and inequality, the erosion of biodiversity, the depletion of fresh water resources and the comfort of life.
