Environmental protection, sustainability, and the fight against climate change are 'vital' topics in this early part of the Third Millennium. People are becoming increasingly interested in issues related to the future of the Earth, particularly the younger generations. Attitudes and choices that impact, inevitably, on companies. Without respect for the planet, the management of its resources, and attention to future generations, it is not possible to imagine a sustainable tomorrow. In this scenario, if it is true that the Earth is not an inheritance received from our ancestors but a loan to be returned to our children, companies too are called upon to make their contribution, promoting virtuous, responsible, sustainable behaviour. It must be said that general attention to the environment, from this point of view, is increasing and companies, in the wake of Agenda 2030 and the 17 Sustainable Development Goals, are doing their part. The PNRR itself goes in this direction: 59.47 billion (about 37% of the total funds) have been allocated to the green revolution and ecological transition.
